2. Vanadium lithium secondary battery (BAT1)
• Types of data this battery backs up: Image data (data of fax transmission and
receiving).
• IC which this battery backs up: DRAM on the image processor PCB (IC7, IC8, IC9,
IC10).
• Amount of back-up time: approximately 3 hours (in an environment subject to nor-
mal temperatures and normal atmospheric pressure, where the power switch of
the main unit has been ON continuously for one day or more).
• Effective life of the battery: approximately 5 years, or until the battery has been
100% discharged 40 times).
The BAT1 of the main unit cannot be replaced as a single unit. For this reason, when
the battery dies, it is necessary to replace the image processor PCB.
The data this battery protects are the image data from transmitting and receiving
faxes. It does not store the image data from the usage of the memory copy function.
:
Caution
Should the length of time noted above as "amount of back-up time" be exceeded, the
backed up data will be erased.
In addition, the image data will also be erased should the jumper plug (JP1), located
on the image processor PCB, be removed. In order to avoid this, when servicing the
unit, please print out the data stored in the memory prior to commencing servicing
operations.
