NOTE: The above data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1, using 1×18650 battery (3.7V, 3400mAh) under laboratory conditions. The data may vary in real-world use due to different battery use or environmental conditions. * The runtime for HIGH mode is the testing result before starting temperature regulation.

Operating Instructions

Battery InstallationInsert one 18650 battery or two CR123 batteries as illustrated.WARNING

1. Ensure batteries are inserted with the positive (+) end pointing to the head. The MH12GT will not operate with incorrectly inserted batteries.
2. CAUTION! Possible dangerous radiation! Don’t look into the light! Maybe dangerous for your eyes.

Momentary Illumination

Press the tail cap switch halfway to switch the light on. Simply release to switch the light off.

ON/OFFTo switch ON: Press the tail cap switch all the way down until a “click” is heard To switch OFF: Press the tail cap switch all the way down again until a “click” is heard

Brightness LevelsWith the light switched on, press the mode switch repeatedly to cycle through brightness levels of ultra-low, low, medium, and high.

ATRWith Advanced Temperature Regulation module, the MH12GT regulates its output and adapts to the ambient environment, maintaining optimal performance.

Special Modes (Strobe/SOS/Location Beacon)When the light is on, press and hold the mode switch for over one second to enter strobe mode; when in strobe mode, press and hold the mode switch for over one second again to cycle through SOS, location beacon and strobe modes. To exit and revert to the brightness level last used, simply press the mode switch. Note: The MH12GT memorizes its previously used brightness level as well as strobe mode the next time it is turned on. (Except for SOS and Location Beacon modes)

Charging Function

The MH12GT can charge a 18650 Li-ion battery with the included USB charging cable by following the steps below.

1.  Click the tail switch to turn on the light.
2.  Connect the USB cable to the MH12GT’s charging port and a power source (USB chargers, PC or other power terminals) as shown in the adjacent image. Fully charging a depleted 18650 battery takes approximately 6 hours. Under normal charging conditions, the blue power indicator light will blink once per second. If CR123/RCR123 batteries are inserted, or there is no battery inserted, or the tail switch is not at the “on” position, the blue power indicator light will blink rapidly to notify users. When charging is completed, the MH12GT will terminate the charging process automatically and the blue power indicator keeps on.

Power Tips

1. When the light is on, the power indicator will blink once every two seconds when power level drops to 50%; the power indicator will blink quickly when power level is low.
2.  When the light is off, press tail cap switch while holding down the mode switch to activate the power indicator light to report battery voltage (accurate to ±0.1V). For example, when the battery voltage is at a maximum charge of 4.2V, the power indicator will blink 4 times, followed by a one-second pause and 2 more blinks before entering the previously used brightness. Different voltages represent the corresponding remaining battery power levels:

Changing Batteries

Batteries should be recharged or replaced if any of the following occurs: The power indicator blinks rapidly; output appears to be dim or the flashlight becomes unresponsive.

Maintenance

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