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.
