The procedure to change the battery is as follows:
1. Place the watch face-down on a flat work surface.
2. Remove both halves of the watch band using a small flat screw-
driver. Note the orientation of the caseback before proceeding;
it must be reinstalled in the same orientation or the buzzer
element will not function after reassembly.
3. Using a 00 Phillips-head screwdriver, remove the four screws
that secure the caseback and put them aside. Carefully remove
the caseback and set it aside.
DO NOT TURN THE WATCH OVER TO REMOVE THE SCREWS OR
CASEBACK – THERE ARE SMALL ELECTRICAL CONNECTORS
INSIDE THE WATCH THAT CAN FALL OUT. ALWAYS KEEP THE
WATCH FACE DOWN ON THE WORK SURFACE.
4. Carefully open the battery clamp and remove the battery.
5. Place a new CR2025 cell in the battery compartment making
