to operate the device.
1. Introduction
Thank you for purchasing our product. This wireless microphone system operates in UHF
band frequency with synthesizer controlled. Thesystem with 16 or 64 selectablefrequencies
via PhaseLocked Loop (PLL) circuitry makes it easy to choosenon-interfered channels.
Pleaseread this instruction manual carefully before operating thesystem.This manual
covers the configurationand operation of thewireless microphone system.
2. Safety
ØDo not spillliquidon the applianceand do not drop it on ahard concrete floor.
ØDo not place the appliance near heat sources such as radiators, amplifier, oretc. Donot
expose it todirect sunlight, extremely dust, excessive moisture, or vibration.
ØTakeout the battery from transmitter, if the appliance has beennot used fora longer
period. This will avoid the damage resulting from a defective leaking battery
3. Environment
ØDo not throwused batteries into afire or garbage bin with domestic rubbish. Be sure to
disposeof usedbatteries inaccordance with local waste disposal rules.
ØWhen disposing the equipment, remove the batteries, separatethe case, circuit boards,
and cables, and dispose of all components inaccordancewith local waste disposal rules.
4. Wireless Note
ØBefore setting up, make sure that the transmitter and receiver are tuned to the same
frequency.
ØDo not use two transmitters inthe same frequency.
ØUse good quality batteries toavoid the damage resulting from adefective leakingbattery.
ØTo avoid interference, do not put the receiver toonear metal object and avoid obstructions
between transmitter and receiver.
ØAvoid theinterference fromTV, radio, otherwireless appliances and etc.

WIRELESS PRODUCT DESCRIPTION
5.2 HandheldMicrophone
The handheld microphone operates inUHF band frequency with PLL synthesized control. UHF
64 preprogrammedselectablefrequencies toavoid interference. Uni-directionaldynamic or
uni-directionalcondensercapsules with different characters for various choices. Use1.5V x2
AA size batteries for lowoperating cost.
1. Grille: Protects themicrophone capsule and helps reduce breathsounds and wind noise.
The grille for thevarious microphone capsules differ inappearance.
2. LowBatteryLED: LED indicates battery life status. Switching the power to "ON", theLED
flashing onceindicates that the transmitter has sufficient power. If the LED stayed on, it
indicates that the battery has insufficient power and shouldbe changed soon. If thestatus
LED fails to flash, the battery is either dead or not positioned correctly, and you shouldcorrect
the positioningor changethe battery.
3. On/off Switch: Turns transmitter power on and off.
4. BatteryCompartment: Insert two AA dry or rechargeable batteries into the compartment
and makesurethat thepolarity of batteries is correct.
5. Group Selector: Changes transmitter Group setting.
6. Channel Selector: Changes transmitter Channelsetting.
7. BatteryCover: Unscrewto expose battery compartment and Group/Channel selector.
8. Color Clip: This color cliphelps to mark the same frequency of receiver and transmitter.
9. ChargingInput: for charging rechargeable batteries insidethebattery compartment using
the using a supplied cablewith 1.5jDC plugs. It needs upto 10hours for charging.

5.3 Bodypack Transmitter
The bodypack transmitter operates inUHF band frequency with PLL synthesized control. UHF 64
preprogrammed selectablefrequencies toavoid interference. Uni-directionalcondenser capsules
with different characters forvarious choices. Use1.5V x2 AA size dry or rechargeable batteries
for lowoperating cost.
1.
On/Off Switch:
Turns transmitter power on and off.
2. Mini XLR /3.5jconnector: Theincluded electret lapelmicrophone is inserted into the
connector on transmitter.
3. LowBatteryLED: LED indicates battery life status. Switching the power to "ON", the
LED flashing once indicates that the transmitter has sufficient power. If the LED stayed on,
it indicates that thebattery has insufficient power and should be changed soon. If thestatus
LED fails to flash, the battery is either dead or not positioned correctly, and you should
correct thepositioning or change the battery.
4. Mic/LineSelector (optional foruse with mini XLR connector) : The switchsets the
audio input either to microphone level or line level.
5. Antenna: Permanently connected, helical antenna.
