CONNECTING THE RECEIVER TO POWER:

Plug the antennas into the TNC socket on the receiver, if the antennas

are detachable. Point the antennas upward. Check that the voltage of

the supplied AC adapter conforms to the voltage available (AC110 or

AC220) in local area. Using the wrong AC adapter may cause irreparable

damage to the unit. Plug the feeder cable of the supplied AC adapter

into DC IN socket on the receiver. Then plug the AC adapter into a

power outlet.

TO A RECEIVER TO AN AUDIO MIXER OR
AN AMPLIFIER:

When using a standard audio cable with 3-pin XLR connectors or 1/8th”

phone plugs to plug into the MIC IN on the audio mixer or on the

amplifier, please push the Volume Button on the receiver to 20 (approx.) ,

the output level for balanced and unbalanced output is around at 77mV.

When using a standard audio cable with 3-pin XLR connectors or 1/8th”

phone plugs to plug into the LINE IN on the audio mixer or on the

amplifier, please push the Volume Button on the receiver to 32, the

output level for unbalanced and balanced output is about at 770mV.

Never use the balanced and unbalanced audio outputs at the same time!

This may cause signal loss or increased noise.

INSERTING BATTERIES INTO THE HANDHELD /

BODYPACK TRANSMITTER:

Open the battery cover and insert batteries into the battery compartment

conforming to the polarity (+)(-) marks. The transmitter can not work with

incorrectly inserted batteries. When push the ON/OFF switch to “ON” to

switch the power on, LCD shows battery power level. If it displays

insufficient power, the inserted rechargeable batteries can be charged

by using the supplied DC 1.5 plug cable directly connection to DC Out

on the receiver and charging input on the transmitter. It should take up to

10 hours for charging. Close the battery cover.

SETTING UP THE HANDHELD MICROPHONE 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 audio mixer or amplifier.

SETTING UP THE BODYPACK TRANSMITTER

A. 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 3-pin 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 audio mixer or amplifier.

B. 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 1/4th” phone plug of the optional guitar cable to the output jack

on the instrument and the 3-pin mini XLR 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 audio mixer or amplifier.

TROUBLE-SHOOTING:

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.
