Power Tips

After battery installation, the blue power indicator will blink to indicate battery voltage (accurate to

0.1V). For example, when battery voltage is at 4.2V, the blue power indicator will blink 4 times,

followed by a one second pause and another 2 blinks. Different voltages represent the

corresponding remaining battery power levels:

On / O Operation

NOTE: The MH20GT utilizes a 2-stage switch. The light’s numerous functions are selected according to

the depth the switch is pressed.

To switch ON: Press the switch all the way down until a click is heard.

To switch OFF: Press the switch all the way down once again to switch the light o and enter standby

mode.

Standby Mode

When in standby mode, press the switch halfway to activate the blue power indicator to ash once every

three seconds, thus helping users locate the MH20GT in dark conditions. Press the switch halfway again

to turn the power indicator o. When using 1x18650 battery, the MH20GT will operate over 12 months

with the power indicator on, or remain standby for over 24 months with the power indicator o.

NOTE: When the MH20GT is left unused for extended periods, Nitecore recommends loosening the

head to lock out and cut o power, thus saving battery power and preventing accidental activation.

1. Under normal charging conditions, the blue power indicator

light will blink twice every three seconds to notify users. When

charging is complete, the blue power indicator will illuminate

steadily.

2. If a problem is detected during the charging process, the

MH20GT will stop charging and the blue power indicator will

blink rapidly. This is usually caused by faulty or incorrectly

inserted batteries.

ATR Technology

Advanced temperature regulation (ATR) technology allows the MH20GT to dynamically adjust

output performance according to its body temperature. This prevents damage from overheating and

prolongs its working life.

Changing / Charging Battery

Batteries should be replaced or recharged when 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.
