1-2 Introduction: Control Head Descriptions
ASTRO Digital Spectra and Digital Spectra Plus radios are available in five models. Table 1-1
provides a description of basic features for the five models covered in this manual.
1.2.1 FLASHport®
The ASTRO Digital Spectra and Digital Spectra Plus radios utilize Motorola’s revolutionary
FLASHport technology. FLASHport makes it possible to add software that drives the radio’s
capabilities both at the time of purchase and later on. Previously, changing a radio’s features and
capabilities meant significant modifications, or buying a new radio. But now, the radio’s features and
capabilities can be upgraded with FLASHport software, similar to the way a computer can be loaded
with different software.
1.3 Control Head Descriptions
1.3.1 General
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 installation in even the smallest of vehicles. Systems that have many
options require more control head buttons, not larger control heads.
The control heads may be field-programmed to add options or alter the information stored in certain
areas of its electronic memory.
The following illustrations show some typical ASTRO Digital Spectra and Digital Spectra Plus control
heads.
