9.3.3 Control Head Installation
Prior to installing the Control Head, verify it has the proper software version installed
and verify that it is properly configured for customer use. Consult the radio system
administration personnel as necessary.
9.3.3.1 Selecting the Mounting Location
When selecting a mounting location, ensure the Control Head
protected from possible damage.
Install and protect the Control Head(s) to avoid direct impact from water and hose-
down, snow, dust, smoke, gases, road debris, oils, chemicals and corrosive agents.
Use splash guards, shields, or covers to protect the Control Head from direct impacts.
When selecting a location for the Control Head, first observe the safety and operator convenience-related
information presented in Section 6.3 on page 28. 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 connectors/cables that must mate to the connectors on the rear panel of the head. The Control Head
can be mounted under or on top of a mounting surface (typically the vehicle’s dash) as space permits using
either the standard U-shaped mounting bracket or the optional mounting pedestal.
The Control Head must be mounted to a mechanically-rigid surface. The Control Head must not vibrate
when the vehicle is in motion and it must remain stable during normal operations by an operator (i.e., button
presses, knob rotation, excessive tugs on the mic cord, etc.). If the Control Head is mounted to a plastic
dash panel, either fender washers or a field-fabricated metal backing plate should be utilized to mount the
head’s bracket to the plastic dash panel.
