may become distorted. To resolve this follow these steps:  
1. Make sure the ignition is turned to the “off” position.  
2. Disconnect both of the harnesses from the CHTO-013.  
3. Locate the potentiometer next to the 14-pin connector at  
the end of the CHTO-013.

potentiometer counter-clockwise to lower the input  
level going to the factory amplifier.
