To insert or replace the battery:
1. Use the nail grip on the battery door.
2. Remove the tab from the new battery.
3. Open the battery door gently and remove
the old battery.
4. Line up the battery’s plus “+” sign (flat side of
the battery) with the “+” on the battery door.
5. Close the battery door.
