Caution:
≥ This product is designed to operate with a 12 V
DC, negative ground battery system.
≥ To prevent damage to the unit, be sure to follow
the connection diagram below.
≥ Remove approximately 5 mm of protective
covering from the ends of the leads before
connecting.
≥ Do not insert the power connector into the unit
until the wiring is completed.
≥ Be sure to insulate any exposed wires from
a possible short-circuit from the car chassis.
Bundle all cables and keep cable terminals free
from touching any metal parts.
≥ Remember, if your car has a drive computer or
a navigation computer, the data of its memory
may be erased when the battery terminals are
disconnected.

Power connector 1
External amplifi er control power lead (max. 500 mA)
This lead is for connection to the power amplifi er.
Note:
≥ This lead is used for power control when an external power amplifi er
is connected. The power supply of a power amplifi er will be activated
when turning on the power of this unit.
Antenna control lead
(to motor antenna) (max.100 mA)
This lead is not intended for use with switch actuated power antenna.
ACC power lead
To ACC power, i12 V DC.
Battery lead
To the car battery, continuous i12 V DC.
Ground lead
To a clean, bare metallic part of the car chassis.
Note:
≥ The power antenna extends automatically when the AM/FM radio
mode is selected.
