Radio Setup



RADIO SETUP

To setup a new radio for the vehicle, complete the setup procedure under the Special Functions menu of the scan tool.

If the new radio is not properly setup, the radio will display a locked message (LOC) or Calibrate.

IMPORTANT: The radio setup will configure the radio amplifier and internal equalization settings.

Without following the setup procedure, the radio will display a calibrate message (CALIBRATE), and the sound quality and volume may be degraded.
