• WARNING
When a third party discovers the password (extension PIN) of the PBX, there will be
a risk that they will make fraudulent phone calls using the telephone line, and the
cost will be charged to your own account. In order to avoid this problem, we
strongly recommend the following points:
a) Carefully maintain the secrecy of the PIN.
b) Specify a complicated PIN as long and random as you can make it.
c) Change the PIN frequently.
• 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 is
locked.
• If you forget your extension PIN or your extension PIN is locked, your manager can clear
the extension PIN and extension PIN lock.
