This has the effect of reducing mistakes and improving work efficiency.

  When changing system parameters from the PHS terminal 1, the parameters that can be displayed and changed by password management are limited, so that maintenance staff and general users can change parameters according to their roles in the same way, and security There is an effect that the maintenance operation can be simplified without loss.

  Conventionally, since maintenance work can be performed only from the management console 5 ', it has been necessary to stand by at the location where the management console 5' is installed. In the present invention, however, the PHS terminal 1 can be entered by inputting the maintenance personnel password. Since the maintenance work can be performed from the beginning, the efficiency of the maintenance work can be improved.

  In addition, by inputting a user password from the PHS terminal 1, the user can change parameters related to the user himself / herself, thereby shortening the period during which the PHS terminal 1 cannot be used for parameter change and improving the service. There is an effect that can be achieved.
