System settings

Transmitter

1. Turn on/off: Press and hold the button for 3 seconds.
2. Group selection: Press SET once, the group prompt light “b1” flashes, and then press the A or button to select the corresponding group.
3. Channel selection: Press SET button twice, the channel prompt light “CH01” flashes, and then press the or button to select the corresponding channel.
4. Setting Exit: During the setting process, stop pressing any button for 5 seconds and automatically exit the setting.

Receiver

1. Turn on/off: Press and hold the button for 3 seconds.
2. Group selection: Press SET once, the group prompt light “b1” flashes, and then the Aor button to select the corresponding group.
3. Channel selection: Press SET button twice, the channel prompt light “CH01” flashes, and then press the or button to select the corresponding channel.
4. Volume adjustment: The top knob key adjusts the appropriate volume level.
5. Setting Exit: During the setting process, stop pressing any button for 5 seconds and automatically exit the setting.
6. Screen lock: During normal operation of the device, after stopping pressing any button for 7 seconds, the screen will automatically dim.
7. Frequency indication: When the group and channel of the receiver are consistent with the group and channel of the transmitter, the RF signal bar of the receiver will change. The reception strength depends on the length of the signal bar. When there is inconsistency, the RF signal bar of the receiver will be blank.
