GENERAL NOTES
M ANUAL C OMPILATION
This manual provides detailed information on the SDB670 DMR Base Station including
Introduction, Specifications, General Description, Technical Description, Maintenance, and Spares.
Details of both “basic” and “optional units” have been included in this Service Manual, therefore,
some material may not be relevant to every system. Configuration is dependent upon the
specification by the customer when the equipment was ordered and installed.
The manual has been compiled with a two-tier maintenance policy in mind, i.e. first-line fault
location and repair by replacement, followed by subsequent bench-testing of sub-assemblies to
specification. Consequently, some “overlap” and/or duplication of information has resulted.
P AGINATION
This manual is divided into a number of sections, each section deals with one aspect of the
system.
Following initial issue, any page that has been amended or updated will also bear an updated
reference.
P ARTS L ISTING
A Composite List of Replaceable Assemblies (i.e. a list of all components used in the system) is
included at Section 7.
