Assembly Instructions

CAUTION: The radio is sold with correct accessory cables and jumpers to have emergency
deactivated by default, regardless of the setting in Customer Programming Software (CPS).
However, if cables are not used, or if jumpers are removed without replacing with an emergency
accessory button/switch at one of the accessory ports, the radio powers up upon the application
of A+. The display may not show an indication that the radio is on, and this condition can result
in an incorrect operation of the radio and excessive current drain of the vehicles battery when
the engine is off.
