Performance Verification (PV) Test

After the FELCOM is installed, the installer usually confirms that it is functioning prop-
erly, by logging in and conducting the PV test. This test consists of receiving a test
message from an LES, transmitting a message to the LES and a distress alert test.
The results of the test appear on the PV test result display.
The PV test cannot be conducted from an auxiliary terminal unit. Note that the test can
also be initiated by an NCS.
