8 CH-25 REMOTE CONTROL HEAD INSTALLATION
Procedures in this section must be performed only for a remote-mount radio installation.
For a front-mount radio installation, advance to Section 9 or 10 now.
8.1 APPLICATION OF THE REMOTE-CONTROL CONVERSION KIT
Before beginning vehicle installation of the CH-25 control head, the CH-25 Remote-Control Conversion
Kit must be applied to the front-mount radio to convert it to a remote-mount radio with a separate control
head. To accomplish this, complete the procedures presented in the kit’s Product Manual, publication
number 14221-1510-4450.
Instructions included in that manual include procedures on removing the control head from the existing
front-mount radio, attaching the radio’s remote interface to the front of the radio thus converting it to a
remote-mount radio, and attaching the control head’s remote interface to the back of the control head.
8.2 REFLASHING THE RADIO (IF REQUIRED)
It is critical that the correct minimum version of firmware is loaded into the front-mount
XG-25M mobile radio prior to starting the physical conversion/separation process. A
remote-mount XG-25M will not recognize the remote-control CH-25 head and the two
will be completely non-functional with an older firmware version. Refer to Product
Manual publication number 14221-1510-4450 for complete details. That manual is
included with CH-25 Remote-Control Conversion Kit DM-ZN9Z
8.3 INSTALLING THE REMOTE-MOUNT RADIO
After completing the procedures in Product Manual 14221-1510-4450, install the remote-mount radio
into its mounting bracket by following the procedure in Section 7.1.4 (page 37).
Also connect/re-connect the 3-pin connector of the DC Power Cable to the 3-pin power connector on the
rear of the radio. The respective cable installation procedure are included in Section 7.2 (page 38).
8.4 CONTROL HEAD MECHANICAL INSTALLATION
After the CH-25 Remote-Control Conversion Kit is applied and the radio is installed into its mounting
bracket, continue by installing the control head, as described in the following subsections:
8.4.1 Selecting the Mounting Location
When selecting a location for the control head, first review and observe the safety and operator-
convenience related information presented in Section 5.1 on page 17. Always consider and include
clearance for the microphone’s connector that must mate to the mic connector on the front panel of the
head, and clearance for the connector of the Remote Control Cable’s that mates to the connector on the
rear panel of the head. The control head can be mounted in, under, or on top of a mounting surface
(typically the vehicle’s dash) as space permits.
The size and weight of the control head necessitate less stringent mounting requirements than the radio.
However, like the radio, the control head must be mounted to a mechanically-rigid surface. It must not
vibrate when the vehicle is in motion and it must remain stable during normal operations by a radio
operator (i.e., button presses, knob rotation, excessive tugs on the mic cord, etc.). If the control head is
