1. Channel indicator
2. Diversity A/B indicator
3. Audio signal indicator
4. IR sensor area (SDR-5200M IrDA/SDR-5100M IrDA)

8. Power switch/volume control
First turn on the Power of the main unit. Then turn on the individual power of the receiver
module. Select a channel that corresponds to the transmitter. When transmitter is turned on,
either A or B diversity indicator will flash to indicate that signal has been received.
SQUELCH (SQ) setting
When a channel is in use and undesired interference signal is received, turn the SQ in
clockwise direction to make the receiver less sensitive and thus less susceptible to interference.
If this still does not solve the problem, it means this frequency is not applicable at current
position. Please switch over to the next channel.
Channel synchronizing of the receiver and microphone
(SDR-5200M IrDA/SDR-5100M IrDA)
1. Effective range between the receiver and transmitter is within 30cm
2. Point the transmitter sensor to align with the receiver sensor.

To change the receiver’s channel, please press the synchronizing button of the microphone.
The microphone will transmit synchronizing signal to the receiver and change its channel.
4.
To change the microphone’s channel, please press the synchronizing button of the receiver.
The receiver will transmit synchronizing signal to the microphone and change its channel.
