16.3 CPU90E Board
CAUTIONS
• After the CPU90E board is replaced, clear the contents of the backup memory and set the
date and time.
"2.3 Clearing Backup Memory, 2.4 Setting Date and Time"
• When servicing any printed circuit board, be sure to wear an anti-static wristband to ensure
proper grounding. If not, static electricity built on the human body may cause damage to
electric parts mounted on the board.
• If the lithium cell is drained, replace the board as a whole.
• The old board replaced should be sent back to the Parts Center (factory).
• If the cell is replaced improperly, it may explode. When the lithium cell is to be replaced, a cell
designated by Fuji or its equivalent should be used. The drained cell should be disposed of in
accordance with the instructions provided by Fuji.
