Pioneer ANH-P9R-BK Installation Manual page 7

Connecting the Units
• 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 igni-
tion switch ON/OFF operations. If this is not
done, the vehicle battery may be drained
when you are away from the vehicle for sev-
eral hours. (Fig. 1)
ACC position
• The black lead is ground. Please ground this
lead separately from the ground of high-cur-
rent products such as power amps.
If you ground the products together and the
ground becomes detached, there is a risk of
damage to the products or fire.
• Cords for this product and those for other
products may be different colors even if they
have the same function. When connecting
this product to another product, refer to the
supplied Installation manuals of both prod-
ucts and connect cords that have the same
function.
