A. General
The HT 1000, MT 2000, MTS 2000, and MTX series
radios have been prepared to meet published specifica-
tions through their manufacturing process, with the use
of laboratory-quality test equipment of highest accuracy.
The recommended field service equipment approaches
the accuracy of the manufacturing equipment with a few
exceptions. Accuracy of the equipment must be main-
tained in compliance with the manufacturers
recommended calibration schedule.
B. Setup

A. Power-up Display Codes
At power-up, the radio performs cursory tests to
determine if its basic electronics and software are in
working order. Problems detected during these tests are
presented as error codes on the radio display. The pres-
ence of an error code should prompt the user that a
problem exists and that a service technician should be
contacted.
Self-test errors are classified as either fatal or non-
fatal. Fatal errors will inhibit user operation, while
non-fatal errors will not. Use...

SECTION V. RADIO ALIGNMENT PROCEDURE
A. General
An IBM PC (personal computer) and RSS (Radio
Service Software) are required to align the radio.  Refer
to the applicable RSS manual for installation and setupprocedures for the software.  To perform the alignment
procedures, the radio must be connected to the PC, RIB
(radio interface box), and Universal Test Set as shown
in Figure 40-1.
