I have been trying
to figure out how to shutdown the calc, the following
routine shuts it
down, but it will not let it turn on again. You have to
take out the
batteries. It doesn't reset the memory though when you do.
Could I get
some help in letting me know a off routine that turns the calc
off then
enables you to turn it back on again.
