c) Post- replacement precautions
(1) When ROM replacement is performed to replace a faulty ROM, service work is completed after
reassembling the fax and turning the power ON.
(2) After ROM replacement is performed to upgrade the ROM version and software switches such as
service data and user data settings must be changed, following operations must be performed. This
is because the pre-replacement settings stored in the memory have been saved by the battery back-
up function.
• Perform an ALL CLEAR operation.
After performing ALL CLEAR, reregister the battery backed-up data which you printed out earlier.
Refer to Chapter 3: 3.1 CS LED lights-on Duration Adjustment on Page 3-6 to reset
the CS LED lights-on duration.
