Auto Power Off
If no key is pressed for three min-
utes, the unit will display the cur-
rent time. If no key is pressed for
a total of five minutes, the unit
will automatically turn off in
order to spare your batteries. It
will feel neglected, and perhaps
eventually file for a separation.
Press any button or slide any
switch to wake the unit up and
return to the time mode.
My Personal Guarantee
I promise I will enjoy spending
the money you blew on this thing.
Seriously, thanks a lot ...

If no button is pushed for five minutes,
your Calculator will turn off to save
your batteries. Just push any button
to wake the unit up.
