usage method:

1. Install the battery: Open the battery box and insert the battery according to the "+" and "-" pole markings indicated on the battery box. The second hand starts running, indicating that the explosion-proof clock is working properly.

2. Needle timing: Turn the needle wheel on the back of the movement to the standard time.

4、 Precautions

1. The explosion-proof quartz clock is an intrinsically safe explosion-proof product, and any changes to the components in the circuit may affect the explosion-proof performance of the explosion-proof quartz clock. Therefore, users are required not to disassemble any electronic components inside the movement.

The power circuit of the explosion-proof clock is equipped with a safety protection device, and the replacement of the battery will not affect the explosion-proof performance of the explosion-proof quartz clock.
