Selecting the Mounting Location
When selecting a location for the CH-721 control head, first observe the safety and operator-convenience
related information presented in Section 5.1 on page 20. Also 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
CH-721 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.

For a “hanging” control head
installation, the pedestal can
be attached to the top of the
head via threaded holes in
the top of the head’s case.
