Maintaining the Unit
Initializing the Unit
Doing an initialization resets some or all settings to their
default values. There are two types of initialization:
• Factory Setting
Resets all settings in the unit to their default values.
This type of initialization also deletes all other data
on the unit, such as the call logs and the phonebook.
Do a Factory Setting initialization before
transferring the unit to a third party, such as for
maintenance. Doing so reduces the risk of an
unauthorized third party obtaining personal data.
• IP Reset
Resets only the network settings to their default
values.
Do an IP Reset initialization when changing the
unit's network environment.
For details about doing an initialization, see "Default
Setting (Page 44)".
