Service manual

A. General
This manual includes all the information necessary
to maintain peak product performance and maximum
working-time using the board-replacement service
approach. This basic level of service (board-level) is
typical of some local service centers, self-maintained
customers, and some distributors. Included in this
manual are: radio specifications for each frequency
band; a general description of ASTRO™ Digital
SABER™ models; basic theory of operation; recom-
mended test equipment, service aids, and tools; radio
alignment procedures; fundamental disassembly/
reassembly procedures; general maintenance recom-
mendations; board-level troubleshooting information;
functional block diagram, connector information; and
an exploded view diagram with parts list of the ASTRO
Digital SABER portable radio. For details on the oper-
ation of the radio or component-level troubleshooting,
refer to the applicable manuals available separately.
To help you with your selection, a list is provided in
this manual, titled “Related Publications Available
Separately.”
Throughout the text in this publication, you will
notice the use of warnings, cautions, and notes. These
notations are used to emphasize that safety hazards
exist, and care must be taken and observed.
NOTE
An operational procedure, practice, or condition,
etc., which is essential to emphasize.
B. Radio Description
The ASTRO Digital SABER radios are among the
most sophisticated two-way radios available. They are
available on VHF, UHF, and 800MHz bands.
One of the newest in a long line of quality
Motorola products, the ASTRO Digital SABER radio
provides improved voice quality across more coverage
area. The digital process called “embedded signalling”
intermixes system signalling information with digital
voice, resulting in improved system reliability and the
capability of supporting a multitude of advanced fea-
tures. Such features add up to better, more
cost-effective two-way radio communications.
ASTRO Digital SABER radios are available in
three basic models. Table 1 provides a description of
their basic features.
C.
The ASTRO Digital SABER radio utilizes
Motorola’s revolutionary FLASHport technology.
FLASHport makes it possible to add software that
drives the radio’s capabilities both at the time of pur-
chase and later on. Previously, changing a radio’s
features and capabilities meant significant modifica-
tions, or buying a new radio. But now, similar to how a
computer can be loaded with different software, the
radio’s features and capabilities can be upgraded with
FLASHport software.
