WIRELESS NOTE
1. Introduction
Thank you for purchasing our product. This PLL synthesized wireless microphone system
operates in UHF band frequency with 16 selectable channels. Please read this instruction
manual carefully before operating the system. This manual covers the function and
operation of the wireless microphone system.
1.1 FCC Statement
This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions: (1)This device may not cause harmful interference and (2) This device must
accept any interference received, including interference that may cause undesired operation
Notice : The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, no
change to the antenna or the device is permitted. Any change to the antenna or the device
could result in the device exceeding the RF exposure requirements and void user’s authority
to operate the device.
1.2 Safety
ž Do not spill liquid on the appliance and do not drop it on a hard concrete floor.
ž Do not place the appliance near heat sources such as radiators, amplifier, or etc.
ž Do not expose it to direct sunlight, extremely dust, excessive moisture, or vibration.
ž Take out the battery from transmitter, if the appliance has been not used for a longer
period. This will avoid the damage resulting from a defective leaking battery.
1.3 Environment
ž Do not throw used batteries into a fire or garbage bin with domestic rubbish. Be sure to
dispose of used batteries in accordance with local waste disposal rules.
ž When disposing the equipment, remove the batteries, separate the case, circuit boards,
and cables, and dispose of all components in accordance with local waste disposal rules.
1.4 Wireless Note
ž Before setting up, make sure that the transmitter and receiver are tuned to the same
frequency.
ž Do not use two or above transmitters operating in the same frequency.
ž Use good quality batteries to avoid the damage resulting from a defective leaking battery.
ž Turn the MIC/LINE switch on the rear of receiver to adjust receiver output level to match
input level requirements of an audio mixer or amplifier.
ž While checking sound, move the transmitter around the area where you use the system to
look for dead spots. If you find any dead spot, change the receiver position. If it does
not work, avoid such places.
ž To avoid interference, do not put the receiver too near metal object and avoid obstructions
between transmitter and receiver.
ž Avoid the interference from TV, radio, other wireless appliances and etc.
SYSTEM FEATURES

3.2 Handheld Microphone
The handheld microphone operates in UHF band frequency with PLL synthesized control. UHF
16 preprogrammed selectable frequencies to avoid interference. Uni-directional dynamic or
uni-directional condenser capsules with different characters for various choices. Use 2 x DC1.5V
AA size dry or rechargeable batteries for low operating cost.
1. Grille: Protects the microphone capsule and helps reduce breath sounds and wind noise. The
grille for the various microphone capsules differ in appearance.
2. Low Battery LED: LED indicates battery life status. When turn on the power, the LED will
stay on to indicate the batteries have sufficient power. Contrarily, if the LED fails to light, the
battery is either dead or not positioned correctly. If the LED stays flashing, it indicates that the
battery will out of power soon and should be changed.
3. Power: Press for 2 seconds to turn transmitter on or off.
4. Battery Compartment: Insert two AA dry or rechargeable batteries into the compartment and
make sure that the polarity of batteries is correct.
5. Channel Selector:
6. Battery Cover:
Changes transmitter Channel setting.
Unscrew to expose battery compartment and Channel selector.
7. Color Clip: This color clip helps to mark the same frequency of receiver and transmitter.
3.3 Bodypack Transmitter
The bodypack transmitter operates in UHF band frequency with PLL synthesized control. UHF
16 preprogrammed selectable frequencies to avoid interference. Uni-directional condenser
cartridges with different characters for various choices. Use 1.5V x 2 AA size dry or rechargeable
batteries for low operating cost.

1. Power: Press for 4 seconds to power the transmitter on or off.
2. Mini XLR Connector: The included electret lapel microphone is inserted into the connector
on transmitter.
3. Antenna: Permanently connected, helical antenna.
4. Low Battery LED: LED indicates battery life status. When turn on the power, the LED will
stay on to indicate the batteries have sufficient power. Contrarily, if the LED fails to light, the
battery is either dead or not positioned correctly. If the LED stays flashing, it indicates that the
battery will out of power soon and should be changed.
5. Channel Selector: Changes transmitter Channel setting.
6. Mic/Line Selector: The switch sets the audio input either to microphone level or line level.
7. Gain: The rotary control adjusts the input audio level of the transmitter. The gain adjustment
range is 10dB.
8. Mic Unit: The uni-directional electret condenser unit features the wide frequency response
for warm, rich bass and clear sound.
