Data In The Control Processing Memory (Sram) - Canon FAX-L260i Service Manual

FAX-L260i Chapter 1: General Description

5.4.2 Data in the control processing memory (SRAM)

SRAM is backed up by a lithium battery. It can retain the stored data for 5 years after the power is turned off.
SRAM stores the following data: All the data the user entered with the user data, the activity reports and other
report-generating data, the redial data containing the redial destinations set with the Redial button, the servicing
data set by repair personnel with the service soft switch. SRAM stores almost all of the data which can be
entered or set.
These stored data can be checked with various reports.
NOTE
Lithium battery life
The lithium battery can last for over 5 years after the power is turned off.
When the power is on, the lithium battery's power is untapped. Therefore, the actual battery
life can be much longer.
When the lithium battery becomes exhausted, "DATA ERROR" will be displayed after the
power is turned off or on. When this happens, replace the lithium battery. Since the data in
SRAM will be lost when the battery is replaced, it cannot be printed out.
After the lithium battery is replaced and the power is turned on, "DATA ERROR" will be
displayed. Press the START/COPY button to discard the contents in SRAM and initialize it
to the factory defaults.
