If a Power Outage 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 the memory are backed up for about 3 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 a telephone connected to the
machine, depending on the type of telephone you use.
• You can receive telephone calls using a telephone connected to the machine,
depending on the type of telephone you use.
