    *The keypad samples the battery each time a button is pressed. If it has been a long time between uses of the keypad, it may take a couple of button presses to average out the battery state. Environmental factors also play into this. If the keypads are stored in a cold area and are then brought into a warmer area you may see the battery level reported low until the entire unit warms up. The keypads perform to the same level in all battery states.
