11-1. Running-down Lithium Battery

“B” alarm on the front display indicates that the lithium battery for memory backup is
weak and close to its useful life. Prolonged operation of F805AT-BC in this condition
may give rise to a sudden loss of setting information when the system is turned off
(information stored in NOVRAM will not be lost). Once the “B” alarm turns on,
replacement of the battery in earliest possible occasion is recommended (average
expected battery life is about 7 years, depending on usage frequency).

B

An alarm (reversed
red) appears when
the lithium battery is
running down

The replacement battery is available from UNIPULSE and it should be
replaced in our factory: please contact UNIPUSE.
