Canon FAX-L800 User’s Guide ENGLISH
8-25Chapter 8 Using the Memory Features
½ Because your user data and speed dialling 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.
½ 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.
½ 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.
½ Frequently disconnecting the fax unit from the power source shortens the
service life of the battery.
½ To avoid shortening the backup battery service life, use the fax within a
temperature range of 10gC to 32.5gC. If the fax is used in an environment that
is too hot or too cold, this can shorten the service life of the backup battery.
½ If the backup battery can not preserve data even after you plug in the power
source and the fax is left on for 1 day (24 hours), call for service and have the
backup battery replaced.
