Setup and Configuration
1. Turn the ignition on. Adjust the volume on the radio control panel. The red LED should flicker while the volume is changing.

refer to the MECP Advanced study guide (p. 360) if you are unfamiliar with this process.
3. Check volume, balance, fade and EQ settings.
4. If you would like to adjust the chime volume, center channel volume, or minimum volume, do so using one of the methods
outlined on the next page. If you are happy with the default levels, no adjustments are necessary.
Manually Setting the Chime Volume (optional)
You can manually set the level of the factory chime using the programming button on the side of the interface, or the radio dash
panel controls. If you would like to set the chime volume using the AmpPRO PC app please proceed to the AmpPRO PC app
