Thank you for choosing our UHF wireless microphone receiver system. Before use,
please read this manual carefully to know the right operation way in order to have the
best result and excitement. The receiver unit, features with quartz controlled fixed frequency
VHF high band, is compatible with our wireless microphone series for dual or multi channels use.
This series applies tone code squelch design to avoid interference from outside signal and noise.
Sound frequency signal is mixed from both channels,then output through AF output jack.
Remember to use different frequencies with no interference when assemble receivers for
application of multi channels.

2. Channel AVolume Control: control sound volume of CHA.
3. Channel B Volume Control: control sound volume of CH B.
4. Channel A Microphone Signal LED Indicator: when microphone is turned on, RF LED
Indicator will light. It means receiving signal.
5. Channel B Microphone Signal LED Indicator: when microphone is turned on, RF LED
Indicator will light. It means receiving signal.
6. Channel A Sound Signal Indicator: indicate signal from MICA.
7. Channel B Sound Signal Indicator: indicate signal from MIC B.
8. Charger left side LED Indicator: when rechargeable battery is inserted into left side of the
charge, LED indicator will light red, After the battery is fully recharged, LED becomes green
and charger stops charging.

1. Power Supply: Insert adapter DC plug into DC Input Jack at the back of the receiver. Insert
the other AC plug into AC power supply outlet.
2. For better receiving, extend both antennas.
3. Sound Signal Output Jack: Insert one end of the cable connector plug into the signal Output
Jack at the back of the receiver (AF OUT) and the other end of the plug into KTV or amplifier
MIC-IN Jack.
4. This product has to be used in a complete set. The wireless microphone is compatible only
with this unit’s receiver. (Not compatible with other brand’s receiver).
5. For better performance, receiver has to be placed at least 50CM from the ground to avoid
electric waves reflection. Transmitter also has to be placed at least l meter from receiver. If
external antenna is used, it has to be far away from source of noise.
6. If the RF LED indicator of receiver lights when approached by the microphone, it indicates
the system works normally. If the RF LED indicator dose not light, it indicates the system
dose not work normally and need to be examined.
7. When microphone is on, LED indicator will flash once then go off (with power saving circuit).
If LED indicator lights red, it indicates the battery has low power and need to be changed.
8. When microphone’s battery is low, LED indicator will become red. If 9V rechargeable battery
is used, take it out from the microphone and insert it into the battery charger. Full recharging
time is about 10 hours. (Standard battery cannot be recharged. Change with new battery ).
9. Caution: Take out battery from battery charger after full recharging in order to protect battery
life.
10. Distance between receiver and microphone has big influence on the performance of
microphone. During operation the nearer the distance, the better the performance.
11. Remember to turn off microphone then receiver after use to save power.
12. If microphone is not going to be used for a long period of time, take out battery to prevent
damage of PCB from leaking battery.
13. The internal parts and circuit of this product have gone through adjustment by comprehensive
instrument. User is not allowed to open the cover for adjustment, which may cause damage to
normal function.
14. One receiver cannot receiver signal from two same-frequency microphones. If more than 2
microphones are needed, user has to use at least 2 sets of microphones and receivers with
different frequencies to prevent interference. (Microphones with other brand or different
frequency are not compatible with this receiver).

Do not open this product by yourself for adjustment.
If water goes into this product, please turn off the power immediately and
send it to after-sale service department of our company for handling.
One receiver cannot receive signal from two same frequency microphones
simultaneously. Other microphone with different frequency or brand cannot
be used for this receiver.
CAUTION
