If a Power Failure Occurs
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, scan, 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.
To fully charge the built-in battery, it takes approximately 2 hours after when the main
power switch is ON. If the built-in battery is not fully charged, the data may not be saved
properly.
