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.
