Some tips to improve the performance of the system
The transmitter and antenna should be kept in the relative position of accessibility of the
straight line
Don’t put the receiver close to the metal surface or near any digital device (such as CD players,
computer, etc.)
Try to place the receiver in height of 1.5 meters from the ground and the position of a distance
of 1 meter away from the wall
Operation of the microphone
1. Screw the battery box open anticlockwise, then put in battery. Attention: the polarity should
be right.
2. Turn on the microphone, if it does not twinkle or is always lighted you should check the bat-
tery – if the voltage is enough or the battery is well arranged.
Operation of the receiver
1. Pullout antenna a&b, make them perpendicular with the machine.
2. Connect one end to the local DC power socket and the other end to an power supplying
socket, be sure that the voltages are DC 12V/100mA.
3. Connect the audio output
4. Mix output: One end of the audio cable into “out mix” socket, and other end to audio amplifier
or mixer’s mic in or aux in socket.
Separate output: one end of the audio cable into “out.A” socket and other end to audio ampli-
fier or mixer’s mic in or aux in socket. Operation of channel B is the same.
5. Put on the power switch, the power indication light is lighted. When the microphone is work-
ing the signal light of the receiver is lighted. When the microphone is working the signal light
of the receiver is lighted. The receiver’s output voice volume can be controlled by adjusting
the volume knob.
Attention when you install the receiver
It should be 1m high from the floor
It should be more than 1m beyond the wall
Antennas should be put out fully, otherwise it’ll influence receiving signals
