Phillips Screws (4x)
CPU Board Battery
The printer's built-in RAM memory is battery backed-
up by means of a 3V coin-type lithium battery (CR2032)
fitted on the CPU board. If you store valuable data in the
printer's memory, we recommend replacing the battery
at least once a year, to be on the safe side. Proceed as
follows:
1
Turn off the printer.
2
Open the top cover and remove the paper roll.
3
Remove the four Phillips screws that hold the plastic
moulding to the rear of the print mechanism.
4
Carefully manipulate the moulding out from under
the print mechanism so the CPU board becomes
visible.
5
Quickly replace the battery. The RAM package will
keep its contents for 5 minutes without any current
from the battery.
6
Reassemble in reverse order and turn on the printer.
