TROUBLE SHOOTING
7.6 Setting up the bodypack transmitter
A. Connecting a microphone
}- Open the battery cover.
Push the MIC/L1NE switch to "MIC" and use the supplied screw-
driver to adjust the GAIN at appropriate position.
}- Plug the mini XLR connector of the microphone cable into the audio input connector on
the body pack transmitter.
}- Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.
}- Adjust the channel setting of the transmitter according to receiver's channel setting.
}- Test the microphone and adjust the levels on your audio mixer or amplifier.
B. Connecting an instrument
}- Open the battery cover.
Push the MIC/L1NE switch to "LINE" and use the supplied
screwdriver to adjust the GAIN at appropriate position.
}- Plug the 6.3<p phone plug of the optional guitar cable to the output jack on the instrument
and the mini XLR into audio input connector on the bodypack transmitter.
}- Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.
}- Adjust the channel setting of the transmitter according to receiver's channel setting.
}- Play the instrument for testing and adjust the levels on your audio mixer or amplifier.
8. Troubleshooting
Problem
No sound
Solution
}-
Check the power supply of the microphone and receiver.
}-
Check that the transmitter and receiver are tuned to the same
frequenc~.
}-
Check whether the hi-fi appliance is switched on and the receiver
output is connected to audio mixer or amplifier input.
".
Check whether transmitter is too far away from receiver or
SQUELCH control set too high.
}-
Check whether receiver is located too near metal object or there
are obstructions between transmitter and receiver.
Sound interference
>-
Check the antenna location.
}-
When using 2 or above microphone sets simultaneously, make
sure that the chosen frequencies are not interfered.
".
Check whether the interference comes from other wireless
microphones, TV, radio and etc.
Distortion
}-
Check the receiver volume level is set too high or too low.
}-
Check whether the interference comes from other wireless
microphones, TV, radio and etc.
