==========================================================================
Pro-60 (200-0309) Power Sources Faxback Doc. # 15352
You can power your scanner from any of the following:
Internal batteries (not supplied)
Standard AC power (using an optional AC adapter [273-1665])
Your vehicle's battery (using an optional DC auto adapter [270-1560])
Using Internal Battery Power
You can power your scanner from six AA batteries (not supplied). For the
longest battery life, we recommend alkaline batteries (such as Cat. No.
23-552). Or, you can use rechargeable nickel-cadmium batteries (such as
Cat. No. 23-125).
1. If the scanner is on, turn VOLUME OFF/MAX counterclockwise to turn it
off.
2. Press down OPEN on the center of the battery compartment cover and
slide the cover off in the direction of the arrow.
3. Remove the battery holder from the battery compartment.
4. Install six fresh batteries as indicated by the polarity symbols
(+ and -) marked on the battery holder and inside the battery
compartment.
CAUTION: Never mix rechargeable and non-rechargeable batteries.
Use only fresh batteries of the required size and type. Always
remove old or weak batteries. Batteries can leak chemicals that
can destroy electronic circuits.
5. Replace the battery holder in the compartment.
NOTE: The battery holder fits only one way in the compartment.
6. Replace the battery compartment cover.
When the batteries are low, the display flashes and the scanner beeps.
When this happens, replace all six non-rechargeable batteries or recharge
all six rechargeable nickel-cadmium batteries (see "Charging Nickel-
Cadmium Batteries").
Important Information about the External Power Jacks
The PWR jack lets you connect an external AC or DC adapter to operate the
scanner. Connecting an adapter to the PWR jack disconnects the internal
batteries.
NOTE: You can use the PWR jack when either chargeable or non-rechargeable
batteries are installed.
The CHG jack lets you connect an external AC or DC adapter to
operate the scanner. When you connect an adapter to the CHG jack,
the internal batteries remain connected and get recharged.
WARNING: Never use the CHG jack when non-chargeable batteries are
installed. If you try to recharge non-rechargeable batteries,
they could get very hot and might explode or leak acid.
CHARGING NICKEL-CADMIUM BATTERIES
The scanner has a built-in charging circuit that lets you recharge nickel-
cadmium batteries while they are in the scanner.
To recharge the batteries while they are in the scanner, simply connect
an AC or DC adapter into the scanner's CHG jack (see "Using Standard AC
Power" or "Using Vehicle Battery Power").
Charging Tips
It takes about 10 to 18 hours to recharge batteries that are fully
discharged. You can operate the scanner while recharging nickel-cadmium
batteries, but the charging time is lengthened.
Nickel-cadmium batteries last longer and deliver more power if you
regularly let them fully discharge. To do this, simply use the scanner
until the low battery indicator appears on the display. Then fully
charge the batteries.
IMPORTANT: This product is capable of using rechargeable nickel-cadmium
batteries. At the end of the batteries' useful life, they
must be recycled or disposed of properly. Contact your local,
county, or state hazardous waste management authorities for
information on recycling or disposal programs in your area.
Some options that might be available are: municipal curb-side
collection, drop-off boxes at retailers, recycling collection
centers, and mail-back programs.
Using Standard AC Power
You can power your scanner from a standard AC outlet using an optional
AC adapter, such as Cat. No. 273-1665 (not supplied).
WARNING: Do not use an AC adapter's polarized plug with an extension cord,
receptacle, or other outlet unless the blades can be fully
inserted to prevent blade exposure.
CAUTIONS: The recommended AC adapter supplies 9 volts and delivers at
least 300 milliamps. Also, its center tip is set to negative
and its plug properly fits the scanner's PWR and CHR jack.
Using an adapter that does not meet these specifications could
damage the scanner or the adapter.
Be sure you connect the AC adapter to the scanner before you
connect it to a standard AC outlet. Then disconnect the adapter
from the AC outlet before you disconnect it from the scanner.
1. Plug the adapter's barrel plug into PWR.
NOTE: If you installed rechargeable nickel-cadmium batteries in the
scanner, remove the cap from the CHG jack and connect the AC adapter
to the jack. This powers the scanner and recharges the batteries at
the same time (see "Charging Nickel-Cadmium Batteries").
2. Connect the adapter's power module to a standard AC outlet.
Using Vehicle Battery Power
You can power your scanner from your vehicle's battery power using an
optional DC auto adapter, such as Cat. No. 270-1560 (not supplied).
CAUTIONS: The scanner is designed to work in a vehicle that has a 12-volt
DC, negative-ground electrical system. If you are not sure
about your vehicle, check with your vehicle's dealer.
The recommended DC auto adapter supplies 9 volts and delivers
at least 300 milliamps. Also, its center tip is set to negative
and its plug properly fits the scanner's PWR and CHR jack.
Using an adapter that does not meet these specifications could
damage the scanner or the adapter.
To protect your vehicle's electrical system, be sure you connect
the adapter to the scanner before you connect it to the
cigarette-lighter socket. Then disconnect the adapter from the
cigarette-socket before you disconnect it from the scanner.
1. Set the adapter's voltage switch to 9V.
2. Connect the adapter's orange barrel plug to the adapter's cable with
the tip set to - (negative).
3. Plug the adapter's barrel plug into PWR.
NOTE: If you installed rechargeable nickel-cadmium batteries in the
scanner, remove the cap from the CHG jack and connect the DC auto
adapter to the jack. This powers the scanner and recharges the
batteries at the same time (see "Charging Nickel-Cadmium
Batteries").
4. Plug the other end of the adapter into your vehicle's cigarette-
lighter socket.
NOTE: If the scanner does not operate properly with a DC auto adapter
connected to your vehicle's cigarette-lighter socket, you might
need to unplug the adapter and clean the socket to remove ashes and
other debris.

Pro-60 (200-0309) Operation Faxback Doc. # 15354
SETTING THE VOLUME AND SQUELCH
1. Turn SQUELCH fully clockwise.
2. Turn VOLUME OFF/MAX clockwise to about half way. The scanner turns
off.
3. Turn SQUELCH counterclockwise until you hear a hissing noise.
4. Adjust VOLUME OFF/MAX to a comfortable level.
5. Slowly turn SQUELCH clockwise until the hissing noise stops.
NOTES: If squelch is set too low, the scanner can pick up unwanted or weak
transmissions. When this happens, slightly turn SQUELCH clockwise
to decrease the scanner's sensitivity to weaker signals.
If squelch is set too high, the scanner might not pick up any
transmissions. When this happens, slightly turn SQUELCH counter-
clockwise to increase the scanner's sensitivity.
SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES
You can set your scanner to search for:
Transmissions within a limited range of specified frequencies
(limit search).
Transmissions starting from a designated frequency (direct search).
When the scanner finds an active frequency, you can quickly store it in
one of the 10 monitor memories.
NOTE: Your scanner rounds down the entered frequency to the nearest valid
frequency. For example, if you try to enter 151.473, the scanner
accepts it as 151.470.
During a limit search, the scanner searches upward starting from a selected
lower frequency limit, or downward starting from a selected upper frequency
limit.
1. Press PGM, then LIMIT. Lo appears on the display.
2. Enter the lowest frequency in the desired frequency search range, then
press ENTER.
3. Press LIMIT, Hi appears on the display.
4. Enter the highest frequency in the desired frequency search range,
then press ENTER.
5. To search up or down:
One step (5, 12.5, or 50 kHz) at a time - quickly press and release up
or down.
Continuously, until the scanner finds an active frequency - press and
hold up or down for about a second.
- L - and SRCH appear on the display, an indicator flashes under the
next available monitor memory, and the scanner searches through the
specified frequency range either upward (from the lowest selected
frequency), or downward (from the highest selected frequency).
NOTE: While searching either upward or downward, when the scanner
reaches a specified limit (either upper or lower), it
automatically skips to the starting frequency and continues
searching.
6. When the scanner stops on an active frequency, you can either:
Press MON to store it in the next available monitor memory, or
Press and hold UP or DOWN for about a second to continue the search.
7. To stop continuous searching, while UP or DOWN SRCH appears on the
display, press UP or DOWN until the UP or DOWN symbol disappears.
DIRECT SEARCH
During a direct search, the scanner searches upward or downward, starting
from a specified frequency or stored channel.
NOTE: "PRIORITY" must be turned OFF in order to start a "Direct Search".
1. To start a direct search from a specified frequency:
a. Press PGM.
b. Enter the desired frequency.
NOTE: Do not omit digits (except the last zeros) after the decimal

Continuously until the scanner finds an active frequency - press
and hold up or down for about a second.
- d - and SRCH appear on the display, an indicator flashes under the
next available monitor memory, and the scanner searches either upward
or downward starting from the selected frequency.
NOTES: While searching either upward or downward, when the scanner:
Reaches the end of a band, it automatically skips to the
beginning of the next available band.
Reaches the end of the last available band, it automatically
skips to the beginning of the first.
3. When the scanner stops on an active frequency, you can:
Press MON to store it in the next available monitor memory, or
Press and hold UP or DOWN for about a second to continue the search.
4. To stop continuous searching, while UP or DOWN SRCH appears on the
display, press UP or DOWN until UP or DOWN disappears.
LISTENING TO A MONITOR MEMORY
To listen to a monitor memory, press MANUAL, MON, then the number key of
the desired monitor memory.
NOTE: You cannot scan monitor memories.
STORING FREQUENCIES INTO CHANNELS
Your scanner has 10 channel storage banks, each with 20 storage areas
called channels, where you can permanently store a total of 200
frequencies. You can either move a monitor memory to a channel, or you
can manually enter a frequency to store it.
Moving a Frequency from a Monitor Memory to a Channel
Follow these steps to move a monitor memory to a channel.
1. Press MANUAL, enter the channel number you want to store frequency in,
then press PGM.
2. Press MON, then enter the number of the monitor memory that has the
frequency you want to store into the channel.
3. Press ENTER. The scanner stores the frequency into the selected
channel.
Manually Storing Frequencies into Channels
Good reference for active frequencies are Radio Shack's "Police Call Radio
Guide Including Fire and Emergency Services," "Official Aeronautical
Frequency Directory," and "Maritime Frequency Directory." We update these
directories every year, so be sure to get a current copy. See also "Guide
to the Action Bands" in the manual.
Follow these steps to manually store a frequency into a channel.
1. Press MANUAL. MAN appears on the display.
2. Enter a channel number then press PGM. The selected channel number
and PGM appear on the display.
3. To enter a frequency, enter the first digits (up to 3), press symbol,
enter the last digits (up to 4) then ENTER.
For example, to enter the frequency 166 MHz:
You Press You See
MANUAL (NN)CH 000.0000 MAN
8 (NN)CH 8
PGM 8CH 000,0000
166 8CH 166
[.] 8CH 166.
000 8CH 166.000
ENTER 8CH 166.0000 FM
NOTES: The scanner continuously monitors the most recently stored channel.
ERROR appears on the display when you enter a frequency not with-
in the scanner's bands (see "Specifications"). To erase an error,
press CLEAR then repeat Step 3.
4. To program the next channel in sequence, press PGM and repeat Step 3.
NOTE: To change the direction it sequences in, press UP or DOWN before
you press PGM.
To program more channels in any sequence, repeat Steps 2 and 3.
SCANNING THE STORED CHANNELS
1. Press UP or DOWN to select the scan direction.
NOTE: When you first turn on the scanner, the scan direction is always
UP.
2. Press SCAN.
The scanner scans through all non-locked channels in the activated banks
(see "Turning Channel-Storage Banks On and Off" and "Locking Out a
Channel").
NOTE: If the scanner does not scan, re-adjust SQUELCH.
TURNING CHANNEL-STORAGE BANKS ON AND OFF
A more efficient way to scan is to turn off storage banks you do not want
to scan. For example, if you wanted to scan only current police activity,
you would not want the scanner to scan, find, and waste time monitoring
channels in other banks that did not include police frequencies, Instead,
you can turn off the other nine channel-storage banks.
While scanning, press the number key for the bank you want to turn on or
off. The bank indicator turns on or off.
If the bank indicator is on, the scanner scans all channels within that
bank that are not individually locked out (see "Locking Out a Channel").
If the indicator is off, the scanner does not scan any of the 20 channels
within that bank.
NOTES: You can manually select any channel in a bank, even if the bank is
turned off.
You cannot turn off all banks. At least one bank must always
be active.
MANUALLY SELECTING A CHANNEL/FREQUENCY
Selecting a Channel
You can continuously monitor a specific channel without scanning. This is
useful if you want to hear a broadcast on a channel and do not want to miss
any details (even though there might be periods of silence) or if you want
to monitor a locked-out channel (see "Locking Out a Channel").
If the scanner is stopped at a channel you want to continue listening to,
quickly press MANUAL once before it continues scanning again.
NOTES: Pressing MANUAL additional times makes the scanner step through
the channels.
To change the channel step direction, press UP or DOWN before you
press MANUAL additional times.
If the scanner is scanning:
1. Press MANUAL to stop the scanning.
2. Enter the desired channel number
3. Press MANUAL again.
If the scanner is not scanning, enter the desired channel number then
press MANUAL.
Selecting a Frequency
You can manually select a desired frequency. This is useful if you want
to monitor a frequency you have not stored, or a frequency stored in a
locked-out channel (see "Locking Out a Channel").
1. If the scanner is scanning, press MANUAL to stop the scanning.
2. Enter the desired frequency.
3. Press DIRECT. The scanner continuously monitors the selected
frequency.
USING PRIORITY
The priority feature lets you scan through the programmed channels, and
still not miss an important or interesting call on a designated channel.
To use the priority feature, you need to designate a stored channel first
and then turn the priority feature on.
Designating a Channel
1. Press PGM.
2. Enter the desired channel number.
NOTES: You can designate any stored channel as the priority channel, but
you can have only one priority channel at a time.
To "undesignate" a priority channel, either designate another
channel or turn the priority feature off.
3. Press PRI.
Turning the Priority Feature On/Off
To turn on the priority feature, press PRI during scanning. PRI appears
on the display. The scanner checks the priority channel every 2 seconds
and stays on the channel if there is activity. P appears to the left
of the display whenever the scanner monitors the priority channel.
To turn off the priority feature, press PRI. PRI disappears from the
display.
USING DELAY
Many agencies use a two-way radio system that might have a pause between a
query and a reply. To avoid missing a reply, you can program a 2-second
delay into a channel or a frequency. When your scanner stops on a channel
or frequency with a programmed delay, it continues to monitor it for 2
seconds after every transmission before the scanner resumes scanning or
searching.
To program a 2-second delay:
If the scanner is in the scan mode and stopped on the desired channel,
quickly press DELAY before it continues scanning again. DLY appears on
the display.
If the scanner is not stopped on the desired channel, manually select the
desired channel, then press DELAY, DLY appears on the display.
If the scanner is in the search mode, press DELAY. DLY appears on the
display and the scanner programs a 2-second delay into all the frequencies
it finds.
To turn off the 2-second delay on any channel or frequency, press DELAY
while the scanner is monitoring the channel or frequency. DLY disappears
from the display.
LOCKING OUT A CHANNEL
You can scan channels faster by locking out specific channels you do not
want to monitor, such as a continuously active weather channel.
1. Press MANUAL. MAN appears on the display.
2. Enter the desired channel number.
3. Press MANUAL again.
4. Press L/OUT so L/O appears on the display.
When it scans, the scanner skips the locked out channel.
NOTES: There must be at least one active channel in each bank. You
cannot lock out all channels.
You can still manually select locked-out channels.
To unlock a channel, manually select the channel then press L/OUT so
L/O disappears from the display.
USING THE LIGHT
While the scanner is on, press LIGHT to light the display for 5 seconds.
Press any key other than LIGHT while the backlight is on to keep the
display lit for another 5 seconds. To turn off the backlight before it
automatically turns off, press LIGHT.
TURNING THE KEY TONE ON/OFF
Each time you press any of the scanner's keys a tone sounds to verify that
the scanner has correctly accepted your entry.
To turn the scanner's key tone on or off, first turn off the scanner. Then
while you press and hold 2 and ENTER, turn VOLUME OFF/MAX clockwise until
the display appears.
USING THE KEYLOCK
Once you program your scanner, you can protect it from accidental program
changes by sliding KEYLOCK to the right.
The only controls that operate in the keylock mode are SCAN, MANUAL, LIGHT,
VOLUME, and SQUELCH. When you want to change the scanner's programming,
slide KEYLOCK to the left.
CHANGING THE AM/FM/WFM RECEIVE MODE
The scanner scans in the following modes:
AM (amplitude modulation) - Used in aircraft bands and
amateur radio band.
FM (narrowband frequency modulation) - Used in action bands such as
police, fire, ambulance, amateur
radio, etc.
WFM (wideband frequency modulation) - Used in commercial FM broadcasts
and television sound.
The scanner is preset to the most common AM/FM/WFM receive mode for each
frequency range. The preset modes are:
FREQUENCY BAND (MHz) RECEIVE MODE
30.0000 - 87.4950 FM
87.50000 - 107.9500 WFM
108.0000 - 136.9750 AM
137.0000 - 224.9950 FM
225.0000 - 399.9875 AM
400.0000 - 512.000 FM
760.0000 - 999.9875 FM
The preset mode is correct in most cases. However, some ham radio and
military aircraft broadcasts do not operate in the preset mode. If you try
to listen to a broadcast when the scanner is not set to the correct receive
mode, the broadcast might sound weak or distorted.
To change the mode, press AM/FM/WFM. AM, FM, or WFM blinks on the display
to indicate that the displayed receive mode has been changed from the
preset mode.
NOTES: If you change any frequency band's receive mode during a limit or
direct search, the scanner no longer uses any of the preset receive
modes. Instead, the scanner searches for frequencies in all the
bands in the selected mode.
If you change the band mode to WFM during frequency search, your
scanner automatically searches frequencies at 50 kHz steps.
To return to the default settings, press and hold down CLEAR then press
AM/FM/WFM.
For more information, see "Specified Intervals" under "A General Guide to
Scanning."
A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly "line-of-
sight." This means you usually cannot hear stations that are beyond the
horizon.
During the summer months, you might be able to hear stations in the 30-50
MHz range located several hundred or even thousands of miles away. This
is because of summer atmosphere conditions. This type of reception is
unpredictable but often very interesting!
