Operating Instructions

Battery Installation
Insert the battery(s) as illustrated and screw to tighten the tail cap.

Ensure the battery(s) is/are inserted with the positive end towards the head. The product will not work if the battery(s) is/are incorrectly inserted.
Possible dangerous radiation! Don't look into the light! May be dangerous for your eyes.
When the power level is low, please stop using the product and replace or recharge the battery to prevent damage to the battery.
When the product is kept in a backpack or left unused for prolonged time, please remove all batteries to prevent accidental activation or battery leakage.

Charging Function

The MH11 is equipped with an intelligent charging system. As illustrated, after inserting the battery and tightening the tail cap, use the USB cable to connect an external power supply (e.g. a USB adapter or other USB charging devices) to the charging port to begin the charging process.
Charging Function

During the charging process, the blue power indicator will flash slowly to inform the user.
When the battery is fully charged, the MH11 will cease the charging process and the power indicator will become constantly 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 return to its previous status when it is disconnected from the power source.
It is recommended to press the Tail Switch before the charging process to increase the charging power. In this way, the charging time for an 18650 Li-ion battery (2,600mAh) is approx. 2 hours 15 minutes. (Charged via the 5V/2A adapter)

On / Off

On: When the light is off, press the Tail Switch until a click sound is heard to turn it on.
Off: When the light is on, press the Tail Switch until a click sound is heard to turn it off.

Brightness Levels

When the light is on, half press the Tail Switch to cycle through the following brightness levels: LOW – MID – HIGH – TURBO. (The MH11 has memory function. When reactivated, the flashlight will automatically access the previous memorized brightness level.)

Power Indication

When the light is on and the power level is close to 50%, the power indicator will flash every 2 seconds to inform the user. When the light is on and the power is close to depleted, the power indicator will flash quickly and continuously to inform the user. The batteries should be replaced when the output appears to be dim or the flashlight becomes unresponsive due to low power.

ATR (Advanced Temperature Regulation)

The integrated ATR technology regulates the output of the MH11 according to the working condition and ambient environment to maintain the optimal performance.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of silicon-based lubricant.
