POSSIBLE CAUSE
The operating frequency is not set to
a ham band.
Power is set to a lower power than
maximum.
Microphone gain is set too low.
The antenna is not connected properly.
The antenna feed line is cut or shorted.
The antenna is not properly tuned.
The transceiver turning ON the battery
operating mode.
RIT function is activated.
Split function is activated.
Split function is not activated.
An incorrect transmit frequency is set.
Subaudible tone encoder is OFF and
repeater requires a tone for access.
Programmed subaudible tone fre-
quency is wrong.
Microphone gain is set too high.
The compression level is set too high
with the speech compressor ON.
The dial lock function is activated.
The internal CPU has malfunctioned.
Squelch is open.
The same frequencies have been
programmed in scan edge memory
channels.
2 or more memory channels have not
been programmed.
2 or more memory channels have not
scan
been designated as select channels.
SOLUTION
Set the frequency to a ham band.
Set the output power in quick set
mode/initial set mode.
Set microphone gain to a suitable
position using quick set mode.
Reconnect the antenna connector.
Check the feed line and correct any
improper conditions.
Push [TUNE] to manually tune the
antenna.
Check the battery voltage with the
[POWER] pushed IN.
Push [RIT] to turn the function OFF.
Push [(F-1) ] in the display to turn
the function OFF.
Push [(F-1) ] in the
turn the function ON.
Set the proper frequencies into VFO
A and B or into one of the memory
channels.
Use [(F-2) ] in the display to se-
lect FM-T.
Program the required frequency using
FM tone set mode.
Set gain in quick set mode.
Set compression level to a suitable
position.
Push [LOCK] to deactivate the func-
tion.
Reset the CPU.
(While pushing [UP] and [DN] push [POW-
ER] to turn power ON.
Set squelch to the threshold position.
Programm different frequencies into
scan edge memory channels.
Program 2 or more memory chan-
nels.
Designate 2 or more memory chan-
nels as select channels for the scan.
