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.
