PILOT TONE SQUELCH
Pilot Tone indicator (P) present, but no sound (Check audio meter first)
Pilot Tone Indicator (P) keeps flashing when transmitter turned on
Noise on audio and Pilot Tone Indicator is "b"
Rio Rancho, NM
Possible Cause
External power supply disconnected or inadequate.
Wrong polarity power source. The external power input jack requires
POSITIVE (+) to be on the center pin. Battery gets warm and doesn't
work.
Battery may be low. Try fresh batteries.
This indicates an internal error. Please contact the factory for
assistance.
This is a warning that a strong RF signal is present that is not
centered on the channel, and the audio is likely to be distorted.
There are three principal causes:
1) The transmitter is set to the wrong channel, but close to
the correct channel. Check frequency setting of transmitter.
2) A foreign signal is causing the condition, such as from a local
TV station or from intermodulation from another transmitter.
Retune the receiver and transmitter to a clear frequency.
3) The transmitter carrier frequency is not correct (rare occurrence).
Contact factory for repair.
If any of these solutions don't remove the warning message, the
transmitter or receiver may need repair.
This is a warning that Channel 2 frequency is set 4.3 to 4.7 MHz
below Channel 1 frequency. Solution is to move ONE of the Channel
frequencies at least 600 khz (six 100khz steps) either higher or lower.
Audio output cable bad or disconnected.
Audio Output level too low. Use the built-in test tone to verify levels.
Pilot tone detection can take several seconds. Turn on the transmitter
power (and the audio switch on some models) and wait 3 to 5 seconds
for the "P" to indicate steadily.
Transmitter and receiver not on same frequency.
Receiver compatibility mode does not match the transmitter in use.
(See SEL selections from Main Window, COMPAT Window.)
The pilot tone bypass has been activated. Hold SEL and press UP
to reset (works only from the Main Window).
