Frequency Agile UHF Ultra-Miniature Belt-Pack Transmitter

Rio Rancho, NM – USA

Before going through the following chart, be sure that you have a good battery in the transmitter.  It is important that
you follow these steps in the sequence listed.

1)  Battery is inserted backwards.
2)  Battery is dead.
3)  Transmitter not powered up. (See 

Operating Instructions, Power

UP and Boot Sequence.)

1)  Gain control set to minimum.
2)  Battery is in backwards.  Check PWR LED.
3)  Mic capsule is damaged or malfunctioning.
4)  Mic cable damaged or mis-wired.

1)  Transmitter not turned on.
2)  Transmitter battery is dead.
3)  Receiver antenna missing or improperly positioned.
4)  Transmitter and receiver not on same frequency.  Check

switches/display on transmitter and receiver.

5)  Transmitter and receiver not on same frequency block.
6)  Operating range is too great.
7)  Defective transmitter antenna.

1)  Receiver output level set too low.
2)  Receiver output disconnected, or cable defective or mis-wired.
3)  Sound system or recorder input is turned down.

1)  Transmitter gain (audio level) is far too high.  Check SM

Modulation LEDs and receiver audio levels as SM is being used.

2)  Receiver output may be mis-matched with the sound

system or recorder input.  Adjust output level on receiver
to the correct level for the recorder, mixer or sound
system.  (Use the receiver’s Tone function to check level
settings.)

3)  Excessive wind noise or breath “pops.”  Reposition

microphone and/or use a larger windscreen.

4)  Transmitter is not set to same frequency as receiver.

Check that operating frequency on receiver and
transmitter match.

5)  Receiver/Transmitter Compatibility Mode mismatched.

1)  Transmitter gain (audio level) far too low.
2)  Receiver antenna missing or obstructed.
3)  Transmitter antenna missing.
4)  Operating range too great.
5)  Signal interference.  Turn off transmitter.  If receiver’s signal

strength indicator does not drop to nearly zero, this indicates an
interferring signal may be the problem.  Try a different operating
frequency.

1)  Transmitter gain (audio level) too high.  Check gain

adjustment and/or reduce receiver output level.

2)  Talent standing too close to speaker system.
3)  Mic is too far from user’s mouth.

1)  Control Panel is locked.  (See 

Operating Instructions, Locking

and Unlocking the Control Panel.)
