User manual PIONEER FH-P4000R

[. . . ] Refer to the owner's manual for details on connecting the power amp and other units, then make connections correctly. To protect the wiring, wrap adhesive tape around them where they lie against metal parts. [. . . ] To avoid short-circuiting, cover the disconnected lead with insulating tape. Especially, insulate the unused speaker leads without fail. There is a possibility of short-circuiting if the leads are not insulated. If this unit is installed in a vehicle that does not have an ACC (accessory) position on the ignition switch, the red lead of the unit should be connected to a terminal coupled with ignition switch ON/OFF operations. If this is not done, the vehicle battery may be drained when you are away from the vehicle for several hours. Multi-CD player (sold separately) IP-BUS cable Note: Depending on the kind of vehicle, the function of 3* and 5* may be different. In this case, be sure to connect 2* to 5* and 4* to 3*. Before finally installing the unit, connect the wiring temporarily, making sure it is all connected up properly, and the unit and the system work properly. Use only the parts included with the unit to ensure proper installation. The use of unauthorized parts can cause malfunctions. Consult with your nearest dealer if installation requires the drilling of holes or other modifications of the vehicle. Install the unit where it does not get in the driver's way and cannot injure the passenger if there is a sudden stop, like an emergency stop. The semiconductor laser will be damaged if it overheats, so don't install the unit anywhere hot -- for instance, near a heater outlet. If installation angle exceeds 30° from horizontal, the unit might not give its optimum performance. [. . . ] ISO connector Note: In some vehicles, the ISO connector may be divided into two. In this case, be sure to connect to both connectors. [. . . ]
