If power is suddenly lost due to an outage or accidental unplugging, a built-in battery retains the user data settings and the Address Book settings. Any sent or received documents stored in memory are backed up for about 60 minutes.
During a power cut, functions are limited as follows:
- You cannot send, receive, copy, or print documents.
- You may not be able to make telephone calls using an external telephone, depending on the type of telephone you use.
- You can receive telephone calls using an external telephone depending on the type of telephone you use.
