7 RADIO INSTALLATION
7.1 MOUNTING THE RADIO
7.1.1 General Information
The Mounting Bracket Kit for the radio includes a heavy-gauge steel U-shaped mounting bracket. The
radio should be attached to a mounting surface using this bracket. The bracket can be mounted above or
below the radio. Kit contents are shown in Figure 7-2, and bracket dimensions are shown in Figure 7-3.
Both the radio and the mounting bracket have multiple holes in both sides for adjusting the radio within
the bracket. The radio has four (4) threaded mounting holes, two (2) per side, and the mounting bracket
has twelve (12) corresponding holes, six (6) per side. The radio must be secured to the bracket using the
four M5 socket-head screws included in the Mounting Bracket Kit (2 screws per side). The radio can be
positioned straight in the bracket (i.e., parallel with the bottom surface of the bracket), or it can be tilted
up or down at an angle of approximately 15 degrees maximum. When positioned straight in the bracket,
the radio extends approximately 2 inches (5 centimeters) from the front and rear edges of the bracket. In
the rear, additional clearance must be included for cables.
• Front-Mount Radio:
For a front-mount radio installation, the design allows a front-to-rear tilting of
the radio within the bracket for the best viewing angle, and a front-to-rear position offset. Typically,
either titling, or offset, or both, may be applied to a front-mount radio installation to position the
front-mount radio for best operator viewing and control access.
• Remote-Mount Radio:
For a remote-mount radio installation, the radio bracket tilt and the offset
design are generally not put to use, as neither would be necessary. The radio is simply centered within
the bracket and parallel with the mounting surface.
The optional CH-25 Remote-Control Conversion Kit includes a mounting bracket for
the control head. That bracket allows the head’s tilt to be adjusted for best operator
viewing and control access. Control head insta
llation procedures are included in
Section 8 that begins on page 43.
Observe the follow with respect to clearances at the front of the radio:
• Front-Mount Radio:
For a front-mount radio, the area directly at the front of the radio must be
completely clear of all objects (e.g., gear shift, other radio equipment, etc.) so the operator can easily
access and view the radio.
• Remote-Mount Radio:
For a remote-mount radio, the area directly at the front of the radio must
have clearance for the installation and removal of the Remote Control Cable. At least 6 inches (15.2
centimeters) of space is recommended.
The radio’s mounting bracket must be attached to a secure metal surface that meets or exceeds the
minimum 1/16-inch-thick steel sheet metal requirement in accordance with the following
WARNING. For
example, it can be attached directly to the bottom of the dash if the gauge of the sheet metal is high and
the surface is firm and flat, or it can be attached to the transmission hump, etc., if a mounting wedge (not
included) is utilized. The radio weighs approximately 6 pounds (2.7 kilograms).
