What Happens to Memory after a Power Failure
If power to the fax is lost due to a power failure, or if the fax is acciden-
tally unplugged, a built-in battery keeps a trickle of current supplied to
the memory so all the documents currently stored in the memory can be
saved for up to approximately 12 hours.
How Your Registered Data Is Protected
This is what happens when the fax is disconnected:
❏
The backup battery takes over and keeps a trickle of current flowing
to the memory in order to preserve all the documents in the memory
waiting to be sent or printed.
❏
However, if the fax is left off for longer than approximately 12 hours,
all documents in the fax memory will be lost after the battery runs
down, and as soon as power is restored to the fax a Memory Clear
Report is printed that shows you what documents were erased.

❏
Because your user data and speed dialing settings are constantly
refreshed by a lithium battery, they will not be lost as a result of a
power failure, even if power to the fax is cut off for longer than
approximately 12 hours.
❏
When many documents are stored in the fax memory, the fax may
need about 2 minutes to recover after power is restored to the fax.
About the Backup Battery
Here is a list of things to keep in mind about the backup battery.
❏
The backup battery that preserves document data in the memory for
up to 12 hours in case of a power loss is a rechargeable battery, and it
requires about 1 day to reach full charge after power to the fax unit is
restored.
❏
Frequently disconnecting the fax unit from the power source short-
ens the service life of the battery.
