REPLACING THE BATTERY IN THE RAM CARD
The optional RAM card has an internal battery that backs up the stored
data even when the card is removed from the printer. This battery can be
used for more than four years. To avoid losing data from the RAM card,
you should replace the battery before the end of its service life. Follow the
procedure below.
1. Insert the RAM card in the printer as described in Chapter 1.
2. Turn the power switch on to supply power to the RAM card.
3. Unscrew the screw that holds the battery in place and set it aside.
4. Remove the old battery, and install the new battery the same way as
the old.
5. Fasten the battery holder plate with the screw.
6. Turn off the power switch and remove the RAM card.
