control will not work properly. In such case, please change the angle of lighting on the machine, or operate the
remote control close to the remote receiver.
• Low battery voltage will affect the remote control distance. Please replace the batteries with new ones if the remote
control stops functioning correctly, or you notice a reduction in working distance. If the remote control is to be left
unused for a long period or the batteries are depleted, please remove the batteries in order to avoid battery leakage
which may corrode and damage the remote control.
• Never use batteries of different types or mix a new battery with a used one. Always replace batteries in pairs.
• Never try to dispose of batteries in a fire or recharge or decompose batteries. Never recharge, short-circuit,
disassemble/assemble, heat or burn any used batteries. Please dispose of waste batteries according to applicable
environmental regulations. Do not expose batteries to any hot environment, like direct sunlight, over the fire, etc.
