Power
Supply
The power supply system for the computer
is
divided into the main power
supply (two CR2032 lithium batteries) and an auxiliary power supply for
memory backup (one
CR1220 lithium battery).
If
the display contrast remains
weak even after adjustment (see page 9), replace the batteries
as
soon
as
possible
because they are becoming exhausted.
Note:
Be
sure to replace the batteries every two years regardless
of
their use
in
order to
prevent the chance
of
malfunction due
to
battery leakage.
