R-8 Reference information
message that appears when the calculator is on:
Warning: Low Bat.
The HP 39G/40G uses three AAA batteries. Be sure all three
are of the same brand and type. Rechargeable batteries are not
recommended because of their lower capacity and more
sudden demise.
To replace batteries:
1. Turn the calculator off and place the slide cover over the
keyboard to prevent keys from being pressed.
CAUTION
Your calculator can lose memory if it is turned on while the
batteries are being removed.
Under no circumstances should the batteries be deliberately
inserted backwards and the calculator turned on. This may
cause hardware damage and will void the warranty.
2. Remove the battery compartment door from the rear of
the calculator by pressing down on the dimple and
pushing the door off.
3. Replace the batteries within 2 minutes to avoid memory
loss. Position the fresh batteries according to the diagram
inside the battery compartment.
