Operating Instructions

Battery Installation

Insert 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. Avoid direct eye exposure to the beams.

Momentary illumination

Pressthetailcapswitchhalfwaytoswitchthelighton.Simplyreleasetoswitchthelighto.

ON/OFF

To 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 Levels

With the light switched on, press the mode switch repeatedly to cycle through brightness levels

of ultra-low, low, medium and high.

Note: When in high output, the MH12GT will reduce output luminance automatically after 1

minute of use to prevent overheating and extend battery longevity.

ATR

With 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 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 an 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ashoncepersecond.

If CR123/RCR123s are inserted, or there is no battery inserted, or the tail switch is not at the “on”

position,thebluepowerindicatorlightwillashrapidlytonotifyusers.

When charging is complete, the MH12GT will terminate the charging process automatically and

the blue power indicator goes out.

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o,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.
