GENERAL
SYMPTOM DIAGNOSTIC PROCEDURE
Any hardware malfunction PWB substitution is a valid technique for service and repair of the ORION
product, since there are only a few circuit boards in the product:
1. RF Power Amplifier
2. Logic/IF/Audio
3. Synthesizer/Exciter/RX Front End
4. Control Unit Panel Control
5. Control Unit Switching
6. Control Unit RIA (Remote Only)
7. DSP (AEGIS Only)
The service shop should be equipped with a set of the above PWB's which can
be used for substitution. Defective PWB's can be isolated simply by substituting
one at a time. It is recommended that the Logic PWB used for substitution be
pre-programmed with a conventional system and frequency set given in Tables
2 and 3.
ERROR CODES
This section lists all the ORION radio errors and
warnings. Each error code in the list includes an
explanation of what went wrong and what action to take to
correct the problem. The error codes are divided into three
different categories:
1. Fatal Operational Error Codes - These are errors that
are displayed during the radio normal operation or on
the radio power-up (Fatal System Errors). These
errors will cause the radio to reset.
2. Non-Fatal Operational Error Codes - These are errors
that are displayed during the radio normal operation
or on the radio power-up. The radio will not reset.
3. Radio Programming Errors - These are errors that are
displayed on the radio or the programming PC
display during radio programming.
All System Groups ORION
System Errors
Fatal system errors will cause the radio to display an
error message/code and then reset the radio to its starting
operation. The reset condition will remain until the fatal
error(s) is corrected.
Non-Fatal errors are displayed for a short period
(about 2 seconds) then normal radio operation will
resume.
The errors are displayed on the radio as shown in
Figure 6.
