About the lithium battery:
The fax machine uses a lithium battery to retain settings and information
programmed in the machine when the power is turned off. Battery power is
consumed primarily when the power is off. With the power kept continuously off,
the life of the battery is about 5 years. If the battery dies, have your dealer or
retailer replace it. Do not try to replace it yourself.
