NOTICE

Stated data has been measured according to the international flashlight testing standards ANSI/NEMA FL1 using two quality NITECORE

18650 (3.7V 3400mAh) batteries or four SYSMAX

CR123 (3V 1700mAh) batteries under laboratory conditions. The data may vary due to individual usage habits and environmental conditions.

MH40GT

User Manual

blink twice every second.

2. If a problem is detected during the charging process, the MH40GT will stop charging and the red indicator will blink rapidly. This is usually caused by damaged or incorrectly inserted batteries.

3. When charging is complete, the red indicator will illuminate steadily.

Cautions:

1. The MH40GT needs to be turned on in order to enter charging mode.

2. Do not charge batteries of different types or different brands together.

Switching ON/OFF

To switch ON: Press the tailcap switch until a “click” is heard.

To switch OFF: Press the tailcap switch again until a “click” is heard.

Mode Switching

The Nitecore MH40GT has two modes: Turbo and User-defined. These modes are interchangeable by tightening and loosening the flashlight head. Turbo provides 100% output while User-defined contains five selectable brightness levels and functions.

Turbo Mode

Turbo mode (1000 Lumens) is accessed by tightening the flashlight head. In this mode, press the tailcap switch partway down to momentarily turn on MH40GT, and release to turn it off. Momentary illumination can be applied for signaling and tactical purposes.

Note: in Turbo mode, the fast generated heat can increase flashlight temperature and consequently affect user experience or even flashlight life. Therefore, MH40GT will automatically lower its brightness level after 5 minutes in Turbo mode to control temperature and prolong battery life. You can switch back to Turbo mode if necessary, but using Turbo for extended period is not recommended.

User-Defined Mode

User-defined mode is accessed by slightly loosening the flashlight head. In this mode, lightly and rapidly pressing the switch will cycle through brightness and other functions in the following order: “High-Mid-Low-SOS-Strobe”. The MH40GT will memorise the desired setting approximately 8 second after it is turned off.

Maintenance

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