11. AUDIO LEVEL ADJUSTMENT (SENSITIVITY CONTROL)

To change the factory-preset level, follow the procedures below.
Step 1. Holding the microphone body, slide the battery cover
down to open it. The battery cover is designed not to be
removed from the body.
Step 2. Switch on the power of the tuner and microphone.
Step 3. Adjust the audio level control using the supplied
screwdriver. The microphone sensitivity increases as the
control is rotated clockwise, and decrease as rotated
counterclockwise.
Step 4. Adjust the corresponding tuner's volume control so that its knob points to the 2 o'clock position. If the
tuner's AF PEAK indicator remains lit, readjust the microphone's audio level control to the position
that causes the indicator to flash when the tuner output level reaches its peak. The AF PEAK indicator
lights when the output level reaches the point of about 3 dB below the clipping level.
Note
The AF PEAK indicator operates in response to the volume control position.
However, the AF LEVEL indicator (on the WT-4810) indicates the level regardless of the volume
control setting.
Step 5. Replace the battery cover.
