DTMF (TOUCH-TONE) FEATURES
DTMF (Dual-Tone, Multiple Frequency) is another term
for touch-tones
(the tones a telephone produces when you press a
digit). This standard
set of tones is used by many different amateur radio
systems for accessing
programmable features and dialing through autopatches.
Your HTX-212 produces all 16 standard DTMF tones (0-9,
Q, #, A, B, C,
and D). It has six DTMF memories which can each hold
up to 15 digits for
quick transmission. You can also set the HTX-212 to
listen for a specific
set of DTMF tones, and alert you when it detects them
(this feature is
called DTMF Paging). Until it hears the sequence, the
HTX-212 does not
pass any transmissions to the speaker.
Group Calling lets you DTMF page a single person or an
entire group of
people. To use group calling, every person in the
group selects the same
first three digits as their DTMF page sequence. They
then select up to four
additional digits unique to each person. To page an
individual, you transmit
their entire DTMF page sequence. To page the entire
group, you transmit
at least the first three digits of the sequence,
followed by the DTMF
tones for A, B, and C.
Note: Group Calling only works with the HTX-212 and
other transceivers
