Installing Batteries - HP -32S Owner's Manual

If you continue to use the calculator after the battery annunciator
comes on, power can eventually drop to a level at which the display
becomes dim and stored data may be affected. If this happens, the
calculator requires fresh batteries before it will operate properly. If
stored data has not been preserved due to extremely low power, the
calculator displays MEMORY CLEAR.
Installing Batteries
Once the batteries are removed, replace them within a minute to
save Continuous Memory. Have the new batteries readily at hand
before opening the battery compartment. Also, make sure the calcu
lator is off during the entire process of changing batteries.
To install batteries:
1. Have three fresh button-cell batteries at hand.
2. Make sure the calculator is off. Do not press [cj again until the
entire procedure ffor changing batteries is completed. Chang
ing batteries with the calculator on can erase the contents of
Continuous Memory.
3. Hold the calculator as shown. To remove the battery-compart
ment door, press down and outward on it until it slides off
(away from the center).
