Performance Verification (PV) Test

After the FELCOM 12 is installed, the installing technician usually confirms that the unit is functioning properly and is logged in with the Inamarsat C system by conducting the PV test.

The PV test consists of the message reception test, message transmis- sion test and distress alert test.

The results of the test appear on the PV test result display.

Note that the test cannot be conducted from a 2nd DTE. Note also that the test can be initiated by a LES.
