Batteries
The PC-8201 is powered by four AA size (1.5 volt) batteries.
An
optional NiCAD Battery Pack (PC-8201-90) is also available for use in
place of the regular battery pack.
In addition, there is also a back-up system which consists of internal
NiCAD (nickel-cadmium) batteries which automatically switch on for
emergency use.
These batteries charge continuously whenever the
computer is in normal operation.
While tne PC-8201 is in a storage condition the back-up batteries can
maintain the contents of the RAM for up to 30 days, depending
upon how much RAM is in the unit.
Keep in mind that these
batteries cannot actively operate the PC-8201 for very long.
If the main batteries have a low charge, causing the back-up battery
system to be used, the LOW BATTERY LED indicator on the
PC-8201 will light up.
You should change the batteries when this
indicator lights up, since you can only operate the PC-8201 for about
20 minutes from this point.
Storing the PC-8201 for a long time
with a low charge will cause it to become inoperable.
If you continue to operate the PC-8201 with the Low
Battery indicator lit up for more than 20 minutes, the
unit will become inoperable and you will lose all of the
data stored in the RAM.
Batteries should be replaced as soon as possible after the
LOW
BATTERY
LED lights up.
The power switch
should always be turned OFF during change of batteries.
