Figure 8-6: CH-721 System Model Control Head Front Panel
The CH-721 control heads feature a large easy-to-read 3-line graphical vacuum fluorescent display, an
on/off/volume control knob, menu controls and buttons, trunking mode buttons, an emergency/home
button, a scan on/off button, and three (3) preset buttons. Other front panel components include a
microphone connector and LED-type indicators. One LED indicator is the busy indicator that lights when
the radio is receiving a call and one is the transmitter-enabled indicator that lights when the radio is
transmitting. The front panel also has an ambient light sensor for automatic display dimming.

Prior to installing the control head, verify it has the proper software version installed and
verify it has been properly configured for customer use.
Because Installation Kit MAMW-NZN7R contains the most complete set of materials for
installing the radio and control head, the following instructions make repeated reference
to items within this kit. Item numbers given in parenthesis refer to items in the kit as
listed in Table 4-5 on page 30.
