Note: The stated data is measured in accordance with the international flashlight testing standards ANSI/NEMA FL1, using 1 x 18650 Li-ion battery (3500mAh) under laboratory conditions. The data may vary in real world use due to different battery usage or environmental conditions.* The runtime for TURBO mode is tested without the temperature regulation.* TURBO Availability: The TURBO level is only accessible when using an 18650 rechargeable Li-ion battery of an output over 8A or an IMR 18650 high-drain rechargeable Li-ion battery. It is inaccessible when using CR123/RCR123 batteries.
Battery Installation
Insert the battery(s) as illustrated and screw to tighten the tail cap.Note: After the battery insertion, the power indicator will flash to indicate the remaining battery power. Please refer to the “Power Indication” section of this manual for more details.
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.
- CAUTION! Possible dangerous radiation! Don’t look into the light!Maybe dangerous for your eyes.
- When the power level is low using an IMR 18650 Li-ion battery, please stop using the product and remove 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.
- DO NOT submerge the light into any liquid when it is hot. Doing so may cause irreparable damage to the light due to the difference of air pressure inside and outside of the tube.
MH12GTS
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 on the light.Off: When the light is on, press the Tail Switch until a click sound is heard to turn off the light.
Note: MH12GTS has mode memory. When reactivated, the flashlight will automatically access the previous memorized brightness level or STROBE mode (SOS and BEACON excluded).
Brightness Levels
When the light is on, short press the mode button to cycle through the following brightness levels: ULTRALOW – LOW – MID – HIGH – TURBO.
Direct Access to ULTRALOW
When the light is off, press and hold the Mode Button, then click the Tail Switch and release both to access ULTRALOW. (This access does not have the mode memory.)
Momentary Access to TURBO
When the light is on, press and hold the Mode Button to access TURBO. Release to return to the previous memorized brightness level.
Special Mode (STROBE / BEACON / SOS)
Access: When the light is on, double press the Mode Button to access STROBE.Switch: When STROBE is on, long press the Mode Button to cycle through the following special modes: BEACON – SOS – STROBE.
Exit: When one of the special modes is on, short press the Mode Button to exit special modes and access the previous memorized brightness level; or click the Tail Switch to exit special modes and turn off the light.
Charging Function
MH12GTS is equipped with an intelligent charging system. As illustrated, screw to fully tighten the tail cap after inserting the battery, and then use the USB cable to connect an external power supply (e.g. a USB adaptor, a computer or other USB charging devices) to the Micro-USB port located on the tail cap to begin the charging process.
- When the charging status is normal, the charging indicator will flash slowly to inform the user.
- When the battery is fully charged, MH12GTS will cease the charging process and the charging indicator will become steadily turned on to inform the user.
- When the charging status is abnormal (e.g. the battery is broken/inserted incorrectly), MH12GTS will cease the charging process and the charging indicator will flash quickly to inform the user.
- The charging time for an 18650 Li-ion battery is approx. 8 hours.
Power Indication
- When the battery is inserted, the power indicator beneath the side 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 one 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 Mode Button is pressed when the light is off, the power indicator will flash to indicate the remaining power of the batteries:
- Flashing three times indicates that the power is above 50%;
- Flashing twice indicates that the power is below 50%;
- Flashing once indicates that the power is below 10%.
- 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.
ATR
With incorporated Advanced Temperature Regulation module, MH12GTS regulates its output and adapts to the ambient environment, maintaining optimal performance.
Changing Batteries
The batteries should be replaced when the power indicator flashes quickly and continuously and the output appears to be dim or the flashlight becomes unresponsive due to low power.
Maintenance
Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of silicon based lubricant.
