1. Select a location for the base bracket.
If the units are being mounted separately, select a location for the MRU’s Base Bracket and a location
for the LBPA’s Base Bracket. As previously stated, both brackets should be mounted within
approximately twelve (12) inches of each other so the section of the cable which interconnects the
two radios will have sufficient length.
2. Use the Base Bracket(s) as a template or use the dimensional information shown in Figure 7-1 and/or
Figure 7-2, mark and drill mounting holes into the mounting surface for the bracket(s).
3. Deburr all newly drilled mounting holes.
4. Set bracket or brackets in place, install, and tighten the mounting screws.
For the LBPA Base Bracket 1000003678, use at least six (6) screws per bracket: Four (4) in the screw
holes of a bracket’s side tabs and two (2) in its center-most screw holes. If the installation prevents
the installation of six screws, a minimum of four screws installed in the side tabs’ holes is required.
For the MRU Base Bracket FM103111V1, use four (4) screws to secure the bracket to the mounting
surface.
As all installations differ, bracket-to-vehicle mounting screws are not included. Using #10 stainless-
steel machine screws, stainless steel flat washers, and stainless steel self-locking nuts is
recommended. Alternately, #10 stainless steel self-drilling screws, and stainless-steel flat washers
may be used to speed installation time and/or if the underside of the mounting surface is not easily
accessible. Self-drilling screws such as “TEK” screws do not require drilling of a pilot hole prior to
installation.
Do not use common self-threading sheet metal screws because they will loosen over time
with vehicle vibrations.
