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 speed dialing settings. Any sent or received 
documents stored in memory are backed up for about 3 hours.
During a power cut, functions are limited as follows:
You cannot send, receve, copy, or prnt documents.
You may not be able to make telephone calls usng an external telephone, dependng on 
the type of telephone you use.
You can receve telephone calls usng an external telephone dependng on the type of 
telephone you use.
To fully charge the bult-n battery, t takes approxmately 14 hours when the man power swtch s on. If the 
bult-n battery s not fully charged, the data may not be saved properly.
