CALIBRATION AND MAINTENANCE

Repeat the "TEST" program to ensure the validity of the reported fault.

Press END (F4) to exit the CALIBRATE/TEST program. Go to step 5.

Fault Does Not Reappear:

If the fault was temporary - possibly caused by excessive electrical noise or a power line spike - the adjacent message will be displayed:

If the transmitter passes the selftest, it will automatically exit the failsafe mode and resume operation.

5.If a fault exists, on the MXC, press STATUS then ERRORS (F2). Compare the displayed errors with those noted in step 3. Refer to Table 6.1 for a list of errors and corrective action. The MXC screen is shown here.
