Storing your HX-20
Because of its sensitive components, the HX-20 requires some care
even when you’re not using it. This chapter tells you how to store
your HX-20, for a few minutes, a few days, or even a few months.
Storing

few minutes to
a

hours
If you won’t be using your HX-20 for a few minutes, you don’t need
to take any special precautions. You don’t even need to turn it off.
Just put it down, and pick it up again when you’re ready to continue
working with it.
Storing your HX-20...for

hours
to
a
few
weeks
If you know that you won’t be using your HX-20 for at least a few
hours and perhaps for as long as a few weeks, turn if OFF before
you put it away. When you come back to it and turn it on, you’ll find
that the program you were using is still in memory, ready for you to
use again!
Just be sure to store your HX-20 in a place with acceptable
temperature and humidity. (Remember-your car in the summer is
likely to be much too hot for the HX-20. If you must store an HX-20
in your car during hot weather, put it in the trunk, which is likely to
be cooler than the interior of the car itself.)
Storing your HX-20...for
a
few
weeks to
a
few months
If you know that you won’t be using your HX-20 for more than a
few weeks, you must take certain precautions to ensure that the
batteries won’t drain down. You see, even when you turn the HX-20
OFF, it continues to draw a small amount of current from the bat-
teries. This current keeps the memory circuits and calendar clock
active.
Although the clock and the memory circuits require only a
miniscule amount of power, they will discharge the batteries com-
pletely if given enough time. When that happens, the HX-20 will
forget all the programs in its memory, and the batteries, once fully
discharged, may no longer be able to accept a full charge.
Therefore, you should charge the batteries for several hours
before storing the HX-20 for an extended period of time. It would
