Note: The stated data is measured in accordance with the international flashlight testing standards ANSI/PLATO FL 1-2019, using 1 x 21700 Li-ion battery (5,000mAh) under laboratory conditions. The data may vary in real world use due to different battery usage or environmental conditions.
* The runtime of TURBO is tested without the temperature regulation.
* TURBO Availability: The TURBO level is only accessible when using a 21700/18650 rechargeable Li-ion battery with a discharge current over 8A. It is inaccessible when using CR123/RCR123 batteries.

Charging Function

The MH10S 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.

• During the charging process, the power indicator will flash slowly to inform the user.
• When the battery is fully charged, the MH10S will cease the charging process and the power indicator will turn on constantly to inform the user.
• When the charging status is abnormal (e.g. the battery is defective or inserted incorrectly), the MH10S will cease the charging process and the power indicator will flash quickly to inform the user.
• The charging time for a 21700 Li-ion battery (4,000mAh) is approx. 2 hours 45 minutes. (Charged via the 5V/2A adapter)

Operating Instructions

Battery Installation

Insert the battery(s) as illustrated and screw to tighten the tail cap.
Note: After battery insertion, the power indicator beneath the switch will flash to indicate the battery voltage. Please refer to the "Power Indication" section of this manual for more details.

1. 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.
2. Please use the battery magazine when using 1 x 18650 / 2 x CR123 batteries to avoid battery rattling and to ensure a stable contact.
3. 
   Possible dangerous radiation! Don't look into the light! May be dangerous for your eyes.
4. When the power level is low, please stop using the product and replace or recharge the battery to prevent damage to the battery.
5. 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.

On / Off

On: When the light is off, short press the Power Button to turn it on.
Off: When the light is on, short press the Power Button to turn it off.

Brightness Levels

When the light is on, press and hold the Power Button to cycle through the following brightness levels: ULTRALOW – LOW – MID – HIGH – TURBO. Release to select the desired brightness level. (This access has memory function. When reactivated, the flashlight will automatically access the previous memorized brightness level.)

Direct Access to ULTRALOW

When the light is off, long press the Power Button to directly access ULTRALOW.

Special Modes (STROBE / BEACON / SOS)

• When the light is on/off, double press the Power Button to access the STROBE Mode.
• When the STROBE Mode is on, press and hold the Power Button to cycle through the following special modes: BEACON – SOS – STROBE. Release to select the desired special mode.
• When one of the special modes is on, short press the Power Button to exit special modes and turn off the light. (This access does not have memory function.)

Power Indication

• When the battery is inserted, the power indicator beneath the switch will flash to show the battery voltage (±0.1V). For example, when the battery voltage is at 4.2V, the power indicator will flash 4 times followed by a 1.5-second pause and 2 more flashes. Different voltages represent the corresponding remaining battery power levels:
  
  Note: When using two CR123/RCR123 in series, the indicator will show the average voltage between the two batteries.
• 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 or recharged 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 MH10S 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.
