PROBLEM
POSSIBLE CAUSE
No sound
1. AC adapter is not connected to receiver and/or power outlet.
2. Receiver is OFF.
3. Receiver is not connected to mixer or amplifier.
4. VOLUME control on receiver is at zero.
5. Instrument is not connected to pocket transmitter.
6. Transmitter has a different frequency range or is tuned to a different frequency
7. Transmitter on/off switch is at "OFF" or "MUTE".
8. Transmitter batteries are not inserted properly.
9. Transmitter batteries are flat.
10. Transmitter is too far away from receiver or squelch level set too high.
11. Obstructions between transmitter and receiver.
12. No line of sight between transmitter and receiver.
13. Receiver is too close to metal objects.

REMEDY
1. Connect AC adapter to receiver and/or power outlet.
2. Push ON/OFF switch to switch receiver ON.
3. Connect receiver output to mixer or amplifier input.
4. Turn up VOLUME control.
5. Connect instrument to audio input on the pocket transmitter.
6. Use a transmitter with the same frequency range as the receiver or tune
both to the same frequency.
7. Set transmitter on/off switch to "ON".
8. Insert batteries conforming to "+" and "-" marks.
9. Replace transmitter batteries.
10. Move closer to receiver or reduce squelch level.
11. Remove obstructions.
12. Avoid spots where you cannot see receiver.
13. Remove interfering objects or move receiver away from them.
1. Relocate receiver or antennas.
2. Switch off interference sources or defective appliances or tune transmitter
and receiver to a different frequency; have electrical installation checked.
1. Decrease or increase GAIN setting just enough to stop the distortion.
2. Switch off interference sources or defective appliances or tune transmitter
and receiver to a different frequency; have electrical installation checked.
3. Relocate receiver or antennas. If dead spots persist, mark and avoid them.
