Replacing the Batteries
Under normal conditions the batteries can last up to 2 years. If the
battery is low, the trouble light on the keypad will turn ON.
To replace the batteries, remove the top cover by inserting a coin
into the slot located on the bottom right corner and twist. Remove
the screw at the center of the board to expose the batteries.
Replace both batteries with Panasonic CR-2025 lithium batteries
(see diagram).
The NT9005 v1.02 requires that the serial number of the WS4938-2W be deleted and re-
enrolled in order to restore the low battery.
NOTE: The polarity of the battery must be observed, as shown in the diagram above. Improper
handling of lithium batteries may result in heat generation, explosion or fire, which may lead to
personal injuries.
WARNING: Danger of explosion if batteries are installed incorrectly. Replace only with
the same or equivalent type recommended by the manufacturer.
Keep away from small
children. If Batteries are swallowed, promptly see a doctor. Do not try to recharge these
batteries. Disposal of used batteries must be made in accordance with the waste recovery
and recycling regulations in your area.
