6. Rotate the unit to the preplanned mounting angle and
t
ighten the two threaded knobs holding the charger to
the bracket.
7. Referring to Table 1 on page 2 and Figure 2, connect
the red (A+) wire (with the inline fuse) of the supplied
cable to either an unswitched terminal on the fuse box
of the vehicle or directly to the positive (+) terminal of
the battery of the vehicle. Always position the fuse as
close to the voltage source as possible.

8. There are two methods for Step 8:
• Standard wiring to vehicle Switched A+: Charging
OFF with vehicle OFF. For installations where the
radio may be left in the charger with the ignition of the
vehicle switched OFF and minimal vehicle battery cur-
rent drain is important, the standard wiring connection
of the yellow wire to vehicle switched A+ will disable
charging. Connect the yellow (ignition sense) wire (with
the inline fuse) to a switched terminal on the fuse box of
the vehicle. It is important not to connect the yellow wire
to the red lead.
• Note: The charger will remain ON for approximately 30
minutes after ignition is turned OFF.
• Optional wiring to vehicle A+: Charging ON with
vehicle OFF When the radio is left in the charger for
charging with the ignition of the vehicle switched off, the
optional wiring connection of the yellow wire to always
live vehicle A+ will keep the charger ON. The charger, in
this condition will not power down and will continue to
drain the vehicle battery.
9. Connect the black (ground) wire to any convenient vehi-
cle ground. DO NOT connect the black wire directly to
the vehicle battery negative terminal.
10. The white wire is for vehicle repeater operation only.
Please refer to installation instructions of the vehicle
repeater for instructions on the connection of this wire.

11. Recheck all wiring connections, cable routing, and all physical aspects of the installation. Carefully insert the connector on the
en
d of the cable into the mating connector on the back of the charger and test the charger for proper operation. Note that if a
vehicle repeater is installed, verify operation of the repeater before leaving the vicinity of the vehicle.
