Appendix C
THE BATTERIES
The PX-S uses two sets
of
batteries. The main batteries are used to provide
power for running the PX-S. The back-up batteries hold programs in memory
when the main battery voltage falls below a useable value.
This appendix covers points related
to
charging, switching
off
and
removing
the
batteries,
and
replacing them.
Some precautions
on
using the batteries are given in section 2.1.2.
To
prevent
the batteries running down during transportation
or
storage, the batteries are
disconnected during shipment. Your dealer will normally connect them
and
in-
itialize
the
PX-S. Otherwise follow the procedures outlined
in
Chapter 2.
C-l
Charging the Batteries
When the main battery voltage falls below a useable value,
the
message:
CHARGE BATTERY
will appear
on
the screen. The PX-S will then use the backup batteries to preserve
the
programs
and
data
in memory.
If
it
is
convenient
to
use the
AC
adapter,
the
PX-S can be used while
the
batteries are being charged, although they will
take
longer
to
charge.
IF
NO DISPLAY IS VISIBLE
WHEN
THE
COMPUTER
IS FIRST
SWITCHED
ON,
the
batteries may be discharged. The other possibility is
that
the
view angle
of
the
LCD
screen may
be
set incorrectly. When the
AC
adaptor
is
plugged in, the batteries may
be
so low
that
not
enough power
is
available
to
allow
the
PX-S
to
operate
and
to
charge the batteries.
In
this case
no
display
will appear. Wait 10-15 seconds
and
switch
the
main power
on
again with
the
AC
adapter inserted.
