❏
To avoid shortening the backup battery service life, use the fax
within a temperature range of 50°F to 90.5°F (10°C to 32.5°C). 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.
❏
If the backup battery cannot 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.
