SETTING UP THE HANDHELD TRANSMITTER:

• Switch the receiver power on and check the frequency and volume level.

• Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.

• Test the microphone and adjust the levels on your mixer or amplifier.

• When using a standard audio cable with 1/4" phone plugs to plug into

the MIC IN on the audio mixer or on the amplifier, please turn the Volume

Level Control on the receiver to around 1 o'clock position, the output

level for balanced and unbalanced output is about at 77mV.

• When using a standard audio cable with 1/4" phone plugs to plug into

the LINE IN on the mixer, please turn the Volume Level Control on the

receiver to around MAX position, the output level for unbalanced and

balanced output is about at 770mV.

SETTING UP THE BODYPACK TRANSMITTER:

CONNECTING A MICROPHONE:

• Open the battery cover. Push the MIC/LINE switch to "MIC" and use the

supplied screwdriver to adjust the GAIN at appropriate position.

• Plug the mini XLR connector end of the microphone cable into the audio

input connector on the bodypack transmitter.

• Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.

• Test the microphone and adjust the levels on your mixer or amplifier.

CONNECTING AN INSTRUMENT

• Open the battery cover. Push the MIC/LINE switch to "LINE" and use the

supplied screwdriver to adjust the GAIN at appropriate position.

• Plug the 1/4" phone plug of the optional guitar cable to the output jack

on the instrument and the mini XLR plug into audio input connector on the

bodypack transmitter.

• Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.)

power on.

• Play the instrument for testing and adjust the levels on your mixer or

amplifier.

TROUBLESHOOTING:

NO SOUND:

Check the power supply of the microphone and receiver.

Check that the transmitter and receiver are tuned to the same frequency.

Check whether the hi-fi appliance is switched on and the receiver output

is connected to 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 volume level of the receiver is set too high or too low.

Check whether the interference comes from other wireless

microphones, TV, radio and etc.
