MH12

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 MH12 has memory effect to ensure direct access to the previously used brightness
level and strobe when it is resumed.

User Manual

Charging Function

The MH12 is capable of charging one 18650 Li-ion battery with the included USB charging
cable. Press the tail switch, and then connect the USB cable to the MH12's charging port and
a power source (USB chargers, PC or other power terminals) as shown in the adjacent image.
Fully charging one depleted 18650 battery takes approximately 6 hours.

Under normal charging conditions, the blue power indicator light will illuminate steadily to
notify users. When charging is complete, the MH12 will terminate the charging process
automatically and the blue power indicator goes out.

Note: 1. The MH12 charges 1x18650 Li-ion battery only.

2. In order to enter charging mode, switch on the MH12 before charging.

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 with the mode switch being held to activate the
power indicator light to indicate 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:

1 x 18650 battery

2 x CR123 batteries

Changing Batteries

Batteries should be recharged or replaced when any of the followings occurs: The power
indicators 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
silicon-based lubricant.

Operating Instructions

Battery Installation

illustrated.
NOTE: After loading batteries, the blue power
indicator will flash to indicate battery voltage. Please
refer to the “Power Tips” section of this manual for
details.

WARNING

1. Ensure batteries are inserted with the positive (+)
ends pointing to the head. The MH12 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 off.

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 MH12 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 MH12 will reduce output luminance automatically after 3
minutes of use to prevent overheating and extend battery longevity.
