9. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location.
10. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder.
11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe
is avoided.
12. Label this power switch accordingly. For example: “RADIO ON/OFF.”
13. Continue with the speaker installation procedures presented in Section 9.1 on page 68.
7.2.2.3.3 Radio Is “Hot Wired”
In the “hot-wired” configuration, the radio (and its control head) is turned on and off only by the control
head’s on/off/volume control located on the front panel of the control head. In this configuration, the
white wire must be connected to unswitched and fused 12-volt
vehicle power. Follow the procedure
presented in Section 7.2.2.3.1, except connect the white wire to unswitched battery power
instead of
switched (“Accessory”) power. Be sure to fuse this connection with the provided in-line fuse holder and
3-amp AGC fuse.
7.3 TERMINATE CAN PORTS
Add a CAN Terminator to each CAN port connector on the rear of the radio. Two (2) CAN Terminators
are included in the installation kit for this purpose (item 3 in Table 4-3).
A front-mount Unity XG-100M mobile radio installation may be connected to additional
control heads to form a multi-head radio installation. In this case, refer to Section 8.3 for
control head installation procedures.
In a multi-head radio installation with a front-mount XG-100M mobile radio, at least one
CAN port connector on the rear of the radio will not have a CAN terminator mated to it.
Instead a CAN cable will be mated to it for linking to the additional control head(s).
The CH-100 control head cannot be mixed with the CH-721 control head within the same
multi-head radio installation. For example, a remote-mount CH-721 cannot be connected
to a front-mount XG-100M radio with a CH-100 control head.
