teristics are identified in this Service Manual.

Electrical components having such features are identified

by marking with a Axon the schematics and on the parts

PIONEER recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire,
or other hazards.

Product Safety is continuously under review and new
