4. After a user name is chosen, press SET button 3 seconds to store the setting.

Changing output power

Position (left) for low output power and (right) for high output power.
Low output power will reduce the RF transmission distance and high output power can extend the RF transmission distance.
IMPORTANT: The transmitter automatically enters power-saving mode after idling for about 5 minutes and the output level will be reduced. Its previous level will return right after the transmitter receives audio signal again.

Audio input and gain setting
There are two audio inputs with individual control on the rear panel. Each audio input has its own GAIN control to adjust the sensitivity level. Higher sensitivity will lower the dynamic range of input signals, which may result in more noise and feedback problem. Please set the sensitivity at a proper level.
