Troubleshooting guidelines:
No Sound:
• Check the power supply of transmitter and receiver
• Check that transmitter and receiver are tuned to the same frequency
• Check that transmitter and receiver volume/gain knobs are turned up
• Verify that the transmitter is not too far away from receiver
(ALT-9000 = 500 ft. max/WB-9000 = 200 ft. max)
• Verify that receiver is not located near metal objects and that there are not too many
obstructions between transmitter and receiver
Sound Interference:
• Check antenna location on transmitter and verify the beltpack antennas are straight
• Make sure that the chosen frequencies are not experiencing interference
• Verify there are no other wireless devices on the same channel in a close proximity
Distortion:
• Check if the receiver volume level and/or power output levels are set too high
• Verify there are no other wireless devices on the same channel in a close proximity
Excessive Hissing:
• Adjust the AF input at the transmitter base station as low as possible
