GENERAL INFORMATION
1.1 SCOPE OF MANUAL
This addendum updates the following LTR
®
9800-series service manual with the additional infor-
mation needed to service 9800-series SMARTNET™/
SmartZone
®
transceivers.
98xx Series UHF/800/900 MHz Service Manual,
Part No. 001-9800-001
1.2 DIFFERENCES BETWEEN LTR AND
SMARTNET/SMARTZONE VERSIONS
1.2.1 HARDWARE DIFFERENCES
The 98xx SMARTNET/SmartZone transceivers
use the same basic PC boards and mechanical package
used for high tier LTR models. The only change is the
addition of a DSP board that mounts on top of the
current audio/logic board. This DSP board provides
the SMARTNET/SmartZone control and signal
processing functions.
Therefore, use the service manual listed above to
service all boards except the DSP board. Service and
interfacing information for that board is located in
Section 5 of this addendum.
1.2.2 SOFTWARE DIFFERENCES
The audio/logic and DSP board operating soft-
ware (firmware) is unique to this transceiver. In addi-
tion, the programming and tuning software is also
different. Therefore, new Operation, Programming,
and Alignment sections are included in this manual.
The programming and tuning programs are now
Windows
®
based. Therefore, Windows 95, 98, or NT
4 or later is required to run these programs. The
programming software is called PCTrunk
™
, and the
alignment software is called PCTune
™
. Refer to
Sections 1.5.5 and 1.5.6 for more information on
programming and alignment.
1.3 TRANSCEIVER IDENTIFICATION
The transceiver identification (serial) number is
printed on a label that is attached to the chassis. The
information contained in this number is as follows.
