NEC PC-8201A - Back-Up Power; Automatic Shut off

Chapter 1
Back-Up Power
As outlined in the section on batteries, the back up power source
consists of internal nickel-cadmium batteries. The Back Up Power
switch is on the bottom of the PC-8201. This switch must be in
the ON position for the computer to be operated.
If the PC-8201 is stored unused for more than 30 days this switch
should be set to OFF to prevent the total discharge of the batteries
and deterioration in performance.
■ When the Back Up Power switch is turned OFF the RAM
is completely erased, so it would be wise to copy
important files or data onto cassette tape prior to turning
OFF the back up power.
Automatic Shut Off
When the PC-8201 is ON and no key has been pressed for over 10
minutes, the unit's power will automatically be shut off to prevent
excess discharge of the batteries. When the automatic shut off
function has been activated the Power ON/OFF switch would have to
be manually set to the OFF position before turning the PC-8201
back ON.
The predetermined time period of 10 minutes for the
automatic shut off can be altered using a BASIC language
POWER command. The automatic shut off feature may
be cancelled by the use of the POWER CONT statement
when the AC power adapter is connected to the
PC-8201. See the BASIC Reference Manual for explana¬
tions of these commands.
The only time that the automatic shut off cannot be
activated is when the PC-8201 is in the TERM mode of
the TELCOM feature or when a BASIC program is being
run. See Chapter 8 for details.
