>From P. 66 of the on-line manual: 

Parameter Initialization
Menu parameters are stored in non-volatile memory (EEPROM and/or FLASH). It
is possible, though rare, for
parameters to become altered in such a way as to prevent the firmware from
running correctly. If you suspect
this, you can reinitialize parameters to defaults, then restore a
previously-saved configuration (or re-do all
configuration steps manually; no test equipment is required).
• If you have a computer available to do configuration save and restore, run
the K3 Utility program, then use
the Configuration function to save your present firmware configuration.
• If you don’t have access to a computer, you should write down your menu
parameter settings. The most
important are CONFIG:FLx BW and CONFIG:FLx FRQ (for each installed filter ,
also tap SUB to
obtain sub receiver crystal filter settings, if applicable). You should also
note the settings of option module
enables (all CONFIG menu entries starting with ‘K’, e.g. CONFIG:KAT3) . If
you don’t record your crystal
filter and option settings, you may have to remove the K3’s top cover (and
sub receiver, if installed) to
verify which options as well as crystals filters are installed, as well as
the frequency offsets noted on the
crystal filters (depends on filter type).
• Turn the K3 OFF (using the K3’s POWER switch, not your power supply).
• While holding in the SHIFT/LO knob (which is also labeled NORM below),
turn power ON by tapping the
K3’s POWER switch. Let go of the SHIFT/LO knob after about 2 seconds. You
should now see EE INIT
on the LCD.
• When EE INIT completes after a few seconds, you may see ERR PL1 or other
error messages due to
initialization. Tap DISP to clear each message.
• If you have a computer, restore all parameters using the Configuration
function of the K3 Utility program.
• If you don’t have a computer, manually re-enter all menu parameters that
you wrote down, above, then redo
firmware configuration and calibration (starting on pg. 46). You can omit
any steps pertaining to
parameters you’ve already restored manually.
• See if the original problem has been resolved.
