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.

C A U T I O N 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.
