SYMPTOM

Any hardware malfunction

GENERAL

DIAGNOSTIC PROCEDURE

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.
