2. Put two new AA alkaline batteries on the 5th. Make sure that

the polarity of the battery install (Figure). Warning: Do
not install the wrong battery polarity, which may damage
electronic components within the transmitter.

3. Afresh spin on transmitter lower part case

☞Body Pack Transmitter Battery Instruction

1. Soft depress battery cover on both sides, can open the battery

warehouse.( following diagram)

2. Put two new AA alkaline batteries on the 5th. Make sure that the

polarity of the battery install(Follow the battery polarity

warehouses instructions)

3. Cover positions back to the battery cover

(Note:When system is not in application for a long period of
time,please turn the device off and take out the battery.)

Notes

＊Please choose non-intermodulation frequency setting.within 50 MHz

bandwidth,Usually 4-8 transmitters can be used at the same time.If more
sets of wireless microphones are needed,devices with other frequency
band should be applied.

＊There should be appropriate distance between the receiver and

transmitter,not too near,at least 1 meter distance.

＊If receiving condition seems not to be as good as expected,extended

cord,exterior high-gain antenna,and even antenna amplifier can be

applied.
＊The receiver and transmitter must be set the same frequency channel.
＊When several sets of receivers are used together,it is recommended to

use high-gain antenna,antenna amplifier and receive branch unit.
＊When receiver adopts the omni-directional antenna,please keep the

antenna away from the wall at least 0.5 mm,and also away from any other

metal objects.

＊The transmitter should at least 20cm apart when multiple transmitters

are used together,so as not to interfere each other

＊When you use Handheld Microphone,please hold the middle of the

mic.Body.If too close to the Microphone grille,it will affect the sound
pick-up;if too Close to the antenna (at the bottom of the
microphone),transmission efficiency and working distance may be
reduced.

＊Increase and reduce treble or bass by adjust the distance between

microphone and mouth.

＊The Body Pack Transmitter adopts 1/4 wavelength whip antenna,please

never let the antenna contact human body directly,nor tie with the
microphone caoble together,otherwise it will reduce the operation
effects.

＊To reduce the voice fluctuation when head moves,please keep the

collar-worn microphone as close as possible to the middle,and the
microphone connections should also be fixed tightly to avoid friction
noise.

＊When collarworn microphone is applied for live sound

reinforcement,directional microphone capsule should be used.Selection
and position arrangement of speakers should be made in consideration of
feedback elimination.When necessary,feedback destoryer should be
equipped.

Trouble Clearing

Problems Solutions

No indication on receiver Link the power supply cable well
