WARNING
When you enable the Outside - Outside Line Call feature of Direct Inward System
Access (DISA) function, if a third party discovers the password (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.
