If a Power Failure Occurs
If a power failure occurs, machine functions will be limited as follows:
Depending on your telephone, you may not be able to make telephone calls.
You can receive telephone calls from the optional handset or telephone connected to the
machine.
You cannot send, receive, or copy documents.
If power is suddenly lost due to a power failure or accidental unplugging, the machine may
lose any data stored in the memory, including received fax documents. If this happens, the
LCD displays <LOST IMAGE> when power is restored and automatically prints a Lost Report
(unless the cartridge is empty or there is no paper in the machine) that lists the documents
(received in the last 60 transactions) that were lost from memory as a result of the power
cut.
