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.
Battery Installation
Charging Function
The MH12 V2 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 MH12 V2 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 return to its previous status when it is disconnected from the power source
- The charging time for a 21700 Li-ion battery (5,000mAh) is approx. 4 hours. (Charged via the 5V/2A adapter)
Operating Instructions
Battery Installation
Insert the battery(s) as illustrated and screw to tighten the tail cap.
Warnings:
- 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.
- Please use the battery magazine when using 1 x 18650 / 2 x CR123 batteries to avoid battery rattling and to ensure a stable contact.
- CAUTION! Possible dangerous radiation! Don’t look into the light! Maybe 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.
Tactical Momentary Illumination
Half press and hold the Tail Switch to turn on the light momentarily. Release to turn it off.
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.
User Mode Selection
The MH12 V2 provides 2 user modes for different users and situations.
- Daily Mode (Default Setting): In this user mode, there are 4 brightness levels and 3 special modes (STROBE, BEACON and SOS) available. The MH12 V2 will memorize and re-access any of the 4 brightness levels or STROBE Mode (BEACON and SOS excluded) when reactivated, unless it has been switched to the other user mode.
- Tactical Mode: In this user mode, there are only 4 brightness levels and STROBE Mode available. The MH12 V2 will only memorize and re-access HIGH Level or STROBE Mode when reactivated, unless it has been switched to the other user mode.
To select a desired user mode:
- When the light is off, click the Tail Switch while holding the Mode Button.
- Keep holding the Mode Button for approx. 5 seconds until the blue power indicator beneath the Mode Button flashes quickly.
- The indicator will indicate a user mode selected by flashing once for Daily Mode and flashing twice for Tactical Mode.
- The flashlight will be automatically turned on after this process.
Brightness Levels
- Daily Mode: When the light is on, short press the Mode Button to cycle through the following brightness levels: ULTRALOW — LOW — MID — HIGH.
- Tactical Mode: When the light is on, short press the Mode Button to cycle through the following brightness levels: HIGH — MID — LOW — ULTRALOW.
Special Modes (STROBE / BEACON / SOS)
- Daily Mode: When the light is on, keep holding the Mode Button to cycle through the following special modes: STROBE — BEACON — SOS. Release to select the desired special mode.
- Tactical Mode: When the light is on, long press the Mode Button to access the STROBE Mode.
- When one of the special modes is on, short/long press the Mode Button to exit special modes and return to the previous brightness level; or click the Tail Switch to turn off the light.
Power Indication
- When the light is off, click the Tail Switch while holding the Mode Button and then quickly release both buttons to access Power Indication. The power indicator beneath the Mode Button will flash to show the battery voltage (±0.1V). The flashlight will be automatically turned on after this process.
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 MI-112 V2 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.
