When you enable the Outside – Outside Line Call feature of Direct Inward
System Access (DISA) function, if a third party discovers the password (a
DISA security code) of the system, you have a risk that they will make illegal
phone calls using your telephone line, and the cost may be charged to your
account.
In order to avoid this problem, we strongly recommend the following points:
1: Carefully maintain the secrecy of the password.
2: Specify a complicated password as long and random as you can make it.
3: Change the password frequently.
Condition • The manager (jack number 01) can change the DISA security
codes in program [512] “DISA Security Codes”, and change the
number of digits of the DISA security codes in program [530]
“DISA Security Codes Digits Selection” with their extension
password.
