NotEs

1. Please choose non-intenn modulation frequency setting way. Within 25MHz bandwidth, 4 to 8 transmitters can be used at the same time commonly. If more than 8 transmitters would used together, other bandwidth should be applied
2. Appropriate distance should be ke1:p from the microphone to the receiver. At least t meter between them. Too far away or too near would affect the vocal performance ..
3. If signal receiving condition was :not as good as that expected. extended cord, exterior high-gain antenna or antenna amplifier can be used to enhance it.
4. When several sets of receivers are used together, high gain antenna, antenna amplifier and receive branch unit are advised to b,e used.
5. The receiver and transmitter must be set in the same frequency channe1.
6. Less signal interference between receiver and transmi1tter is much better. It is the best if signals from 1transmitter can reach receiver directly.
7.  If the a1rltenna of the receiver is omni–directional, the antenna should keep at least 0.5mm from the wall and keep away from the metal objects.
8. If several transmitter were used together, they should keep 20cm from each other to avoid interference.
9.  If the transmitters were set with small power, 100 transmitter at the same band can be used.
10. Hold the middle of microphone body when using. Too dose to the grill, the sound pickup would be affected. Too close to 1the cable at the bot1tom. transmission efficiency and working distance would be decreased.
11. The position of headset microphone is usually near to ·the mouth. You can adjust the distance between the microphone and mouth to increase the treble or bass.
12.  if the system would not be used for a long time, please turn off it and take th1e battery out.
