8.1.2 Inserting the Radio into the Mounting Bracket
The radio should now be inserted into the bracket according to this procedure:
1. Lay the radio down into the mounting bracket with the front of the radio at the front of the mounting
bracket.
2. Attach the radio into the mounting bracket using the six (6) M5 x 10 mm stainless-steel hex-head
screws, and flatwashers and lockwashers included with the Mounting Bracket Kit (item 1 in the
respective remote-mount installation kit). Tighten all six screws using a
5
/
16
-inch wrench (or a ¼-inch-
drive ratchet with a
5
/
16
-inch socket) until each lockwasher is fully compressed and the radio is firm
and flush in between the brackets.
3. Check the mounting area for proper clearance for cable service looping and for air circulation, plus an
area for securing excess cable.
Proper mounting is one factor that ensures optimal radio performance. An improperly
mounted radio may experience degradation in the quality of voice and data
communications.
8.2 REMOTE-MOUNT RADIO’S DC POWER INSTALLATION
8.2.1 Overview of On/Off Power Wiring Configurations
Radio on/off power control is accomplished by the control head. In a standard installation, when the
control head is turned on, it “wakes-up” the radio via data activity on the CAN link. The following power
wiring configurations are supported:
• Radio turns on and off automatically with vehicle’s ignition switch/key — This configuration
allows the on/off state of the vehicle’s ignition switch/key to control the on/off power state of the
radio. The white wire of the control head’s
DC Power Cable is connected to a fused switched power
source, typically identified as vehicle “Accessory” power. This source must switch on (up to positive
(+) battery voltage potential) when the vehicle’s ignition switch/key turns on, and it must switch off
(to near zero volts) when the ignition switch/key turns off. The required fuse rating is 3 amperes.
When using this configuration, the on/off/volume control must be left in the on position
. Otherwise,
the radio will remain off when the ignition switch/key is on.
In a remote-mount radio installation, to fuse the white wire of the control head’s DC
Power Cable, a yellow waterproof (HFB type) fuse holder and a 3-amp AGC fuse are
included with the cable.
• Radio turns on and off with a manual switch — This configuration is used when, for example, the
radio must remain on even when the ignition key must be removed from the vehicle and
a separate
on/off switch is acceptable. The white wire of the control head’s
DC Power Cable is connected to one
side of a manually-controlled switch, and the other side of this switch is connected to unswitched and
fused vehicle power. The required fuse rating is 3 amperes. When using this configuration, the
on/off/volume control must be left in the on position.
Otherwise, the radio will remain off when the
switch is on.
• Radio turns on with control head’s on/off/volume control (“hot wired”) — This configuration
allows radio on/off power control only via the control head’s
on/off/volume control. It may be desired
if, for example, the radio must remain on even when the ignition key must be removed from the
vehicle and a separate on/off switch is not desired and/or not acceptable. The white wire of the
control head’s
DC Power Cable must be connected to unswitched and fused vehicle power. The
required fuse rating is 3 amperes.
