•HOW TO REPLACE THE BUILT-IN MIC
1. As shown illustration, the MIC has two solder points. One
point A is linked to the MIC CHASSIS and the other point B
is not.
Solder the GND wire (Black) to point A and the MIC wire
(Brown) to point B .
2. Place the MIC and CUSHION, MIC into the HLDR, MIC
make sure they are properly seated into the NET, MIC before
reassembling.
3. Arrange the MIC wires as shown so that it will not cause any
obstructions.
•REASSEMBLY OF MAIN BOARD
1. Slot in the MAIN C.B in the direction of the bold arrow.
