Receiver and transmitter frequency locking and switching A/B transmitter microphone operation instructions:
①Frequency locking steps and methods:
1. Turn on the A/B microphone, press and hold the setting button for 4 seconds. After the LED display screen flashes, release the setting button
2. Turn on the receiver again, and the corresponding A/B indicator light of the receiver
3. Press the A/B microphone setting button again, and the A/B microphone display will flash rapidly screen will no longer flash at a fixed frequency. The corresponding indicator light of the receiver will stay on for use
②Switching A/B microphones:
After turning on the microphone, hold down the setting button for 8 seconds without letting go. If you hold down the setting button for 4 seconds,the LED display screen will flash. At this time, do not release the setting button. If you hold down the setting button for 8 seconds, the LED display screen will no longer flash. At this time,you will see the LED display screen jumping from CHA to CHB or from CHB to CHA, indicating a successful switch.
③Attention:
1. The same set of one to two microphones cannot use two CHA or CHB simultaneously (the microphone transmitter needs to be adjusted to one CHA and one CHB to be used simultaneously)
2. If the lock frequency does not lock for more than one minute or there is no response, please shut down and restart to pair the lock
3. If the A/B microphone has a lock frequency record and then switches to the A/B microphone, it needs to be paired again to use the lock frequency
