Control Heads

The control heads used with ASTRO Digital Spectra and Digital Spectra Plus radios have
microprocessor circuitry that operates the standard and optional features built into the system. The
control-head design allows for installation in even the smallest of vehicles. The control head may be
field-programmed to add options or alter the information stored in certain areas of its electronic
memory.
The following sections describe the control head used by each of the five models.
1.3.1

W3 Control Head

The W3 Hand-Held Control Head (HHCH) is shown below. THe HHCH has been designed as an
alternative to the standard radio control-head approach. It can emulate most radio control-head
functions, including LCD display, volume control, power On/Off, and mode. The HHCH can either
replace the radio control head or be used in dual-control applications, either in conjunction with a
radio control head or another HHCH.
