CHAPTER 4 OPERATION
8.2.1.3 Vanadium Lithium Secondary Battery (BAT2)
The data backed up by the vanadium lithium secondary battery (BAT2) is image data used
for fax transmission/reception, and it does not include the image data for memory copying.
Back-up time:
about 2 hr (assuming that the machine is kept ON for 5 day or more un-
der normal temperature/pressure conditions)
Battery life:
about 5 yr or after repeating charging and discharging 40 times at 100%
If the backup data cannot be stored longer than half the indicated period (even after the
machine has been powered for 5 day or longer under normal temperature and atmospheric
conditions), suspect that the battery has reached the end of its life.
If the foregoing back-up time is exceeded, the image data stored in
SDRAM will be lost. To prevent loss of image data for service work or re-
location, be sure to print out the image data stored in SDRAM before start-
ing the work.
Memo
Memory Clear List
If the memory clear list is automatically printed when the machine is turned
on, the image data indicated on the list is the data that was lost without
back-up. After the list is printed, the image data storage and the control in-
formation will automatically be deleted. The following is a sample of the
memory clear list:
