7. MOUNTING THE RADIO EQUIPMENT
This section provides details on mounting the Low Band Power Amplifier and radio equipment assembly.
The preferred mounting is on top of a firm, flat surface. See
, and refer to the
respective wiring diagram at the end of this manual as necessary. Control head installation procedures are
The Low Band Power Amplifier and radio equipment combination weighs approximately 15- pounds
(6.8 kilograms). This includes the LBPA, MRU radio, and mounting brackets. Consider this weight when
selecting a mounting surface. Refer to the specifications listed in Section 2.1 (page 14) of this manual for
radio and control head weight specifications.
At a minimum, the mounting surface should be 16-gauge (approximately 1/16-inch
thick) steel sheet metal. Mounting to plastic or other material with low tensile and
shear strength could lead to an unsafe and/or failed mounting condition, turning the
Unity mobile and Low Band Power Amplifier and its base bracket into a projectile
during a high-shock incident such as a motor vehicle accident. If the selected mounting
surface does not meet the minimum 16-gauge steel sheet metal requirement, the
surface should be reinforced with a metal backing plate (not supplied) or it should be
reinforced using some other approved mounting method.
Though generally mounted in a trunk or remote location, the Unity mobile and Low Band
Power Amplifier must be kept away from heat sources. Mounting it in a location which is
out of direct sunlight is recommended but not required. Adequate ventilation space must be
provided to the rear and side fins. The radio reduces its RF output power when its ambient
temperature exceeds approximately +140
o
Fahrenheit (+60
o
Celsius).
Before drilling holes and/or installing mounting screws, verify these operations will not
damage or interfere with any existing vehicle component (fuel tank, fuel line, transmission
housing, existing vehicle wiring, etc.). Always check to see how far the mounting screws
will extend below the mounting surface prior to installation. Always deburr drilled holes
before installing screws.
Prior to beginning the installation, verify the Unity mobile has the proper version of
software installed and it has been configured for customer usage.
7.1 INSTALL THE MOUNTING BRACKETS
Two base brackets are included with the installation kits. One bracket (1000003678) is used to mount the
LBPA and the other base bracket (FM103111V1) is used to mount the radio. However, the preferred
installation method is to mount the radio above the LBPA using the LBPA base bracket and the two (2)
extension brackets (FM-018205) included in the LBPA installation kit.
Typically, the base brackets are mounted in the vehicle’s trunk, on the top surface of a trunk tray, or on
the trunk floor. However, it can be suspended from the trunk’s rear deck if the surface is completely flat,
does not require any shimming, and the gauge of deck’s sheet metal is high (16-guage minimum).
