Charging Function **Operating Instructions Wireless Remote Switch**

Charging Function
The MH40S is equipped with an intelligent charging system. As illustrated, after inserting the batteries and tightening the tail cap, pull out the rubber cover and use the USB cable to connect an external power supply (e.g. a USB adapter or other USB charging devices) to the charging port. Then press the Tail Switch to begin the charging process.

• During the charging process, the power indicator beneath the Mode Button will flash slowly to inform the user.
• When a problem is detected during the charging process (the flashlight is off / the batteries are damaged / the battery type is wrong), the MH40S will automatically cease the charging process and the power indicator will be off or flash quickly to inform the user.
• When the batteries are fully charged, the MH40S will cease the charging process and the power indicator will become steadily turned on to inform the user.
• When the light is on, connecting to a power source will automatically turn the light off. The light will automatically turn on when it is disconnected from the power source.
• The charging time for two 21700 Li-ion batteries (5,000mAh) is approx. 2 hours 45 minutes. (Charged via the 12V/1.5A QC adapter)

Note:

1. The Tail Switch must be turned on during the charging process.
2. DO NOT charge batteries of other types or brands.
