Keeping your PIN secret.b. Selecting a complex, random PIN that cannot be easily guessed.c. Changing your PIN regularly.• Valid numbers for an extension PIN are "0" through "9".• If the wrong extension PIN is entered for a preprogrammed number of times, the PIN islocked.• If you forget your extension PIN or your extension PIN is locked, your manager can clear theextension PIN and extension PIN lock.1.3.28 External RelayPreprogrammed extensions can switch on a relay (e.g., alarm) connected to the PBX.Document Version 2010-08 Operating Manual 811.3.28 External Relay
