| Fault Codes
MagnaStar® faults are logged in the Air Radio (ARTU) and are displayed on the handset as a fault code number. The faults and their associated display codes are listed below:

Displayed Fault Code

Description
|
|
|
Fault Code 001----------------------Non-recoverable transceiver fault
Fault Code 002----------------------Over-temperature
Fault Code 004----------------------Synthesizer malfunction
Fault Code 008----------------------OCXO malfunction
Fault Code 016----------------------820 MHz oscillator malfunction
Fault Code 032----------------------20.48 MHz oscillator malfunction
Fault Code 064----------------------Processor fault
Fault Code 128----------------------Load fault
Fault Code 301----------------------Non-recoverable pilot receiver fault
|
If two or more faults occur at the same time, the handset will display the sum of the codes; i.e. if the synthesizer unlocked fault and the OCXO oven failure both occur, then the fault code would read "Fault Code 012" (8 + 4 = 12).
As long as a fault code is displayed on the MagnaStar® handset, the system will not be fully functional (some functions, such as in-plane or Satcom calling may still work). Non-recoverable faults (fault codes that are odd numbers) require that the ARTU power be cycled off for greater than 15 seconds and then powered back on in order for the fault to be cleared. Recoverable faults (fault codes that are even numbers) may clear themselves a few minutes after hanging up all handsets. If the fault does not clear itself, then cycling the power off for greater than 15 seconds may still be necessary. If the fault codes cannot be cleared, the ARTU is defective and needs to be replaced.
Please call 1-888-246-STAR(7827) to order your replacement ARTU.
