POSSIBLE CAUSE
1) Transmitter gain (audio level) far too low.
2) Receiver antenna missing or obstructed.
3) Operating range too great.
4) Signal interference. Turn off transmitter. If receiver's signal
strength indicator does not drop to nearly zero, this indicates an
interfering signal may be the problem.
Use a clear operating frequency.
1) Control Panel is locked. (See Operating Instructions, Locking
and Unlocking the Control Panel.)
Reminder that it is necessary to hold down the AUDIO or FREQ
button to make adjustments to the audio gain or frequency settings.
Indication that the PLL is not locked. This is a serious condition
that requires factory repair. It may be possible to operate on
another frequency far removed from the one that was selected
when the unlocked condition was indicated.
