When using the CHTO-013 with a radio that has a high audio
pre-out voltage, usually greater than 2 volts, the audio signal
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.
4. Taking a small flat headed screwdriver, turn the
potentiometer counter-clockwise to lower the input
level going to the factory amplifier.
5. After making the adjustment reconnect the wire harnesses.
