There is a lithium battery on the module. Do not attempt

to replace this battery. There is a danger of explosion if

the battery is incorrectly replaced.

If the lithium battery stops working, return the circuit

board to the supplier. Batteries may cause a fire when in

contact with metal. If you need to dispose of the circuit

board and/or the lithium battery, wrap the battery in

non-conductive tape. Check with your local government

for battery disposal regulations.

WARNING: Do not store the batteries in such a way

that they come into contact with each other or with

any piece of metal. Explosion or fire may occur. Should

fire occur, use only dry chemical fire extinguishers. Do

not use water to put out the fire.

Do not heat the batteries. Do not dispose of the batter-

ies or circuit boards in a fire. Do not disassemble the

batteries. Do not apply pressure to or deform the bat-

teries. Ensure that the above precautions are strictly

observed by related departments, including, but not

limited to, production, sales and outside contractors.
