Battery Installation and Replacement:
The gauge comes standard with a quantity of three AAA alkaline batteries
(installed). Use either Duracell MN2400, MX2400 or Energizer E92BP,

2) Hold the keypad in the palm of hand.
3) Carefully remove the three batteries from the holder and replace the bat-
teries. Use only AAA alkaline non-rechargeable batteries.
