Operation instructions

Battery installation (as the picture shows)

1. Unscrew the tail cap in a counter-clockwise direction.

2. Insert two 18650 batteries or four CR123 batteries with the positive pole

pointing forward (toward the light head).

User Manual

Switching ON/OFF

Switch ON: Press the button on the tailcap until a “click” is heard.
Switch OFF: Press the button at the tailcap until a second time until a “click” is
heard.

Mode Switching

The Nitecore MT40 has two modes: Turbo and user-defined. These two modes
can be changed by simply tightening and loosening the flashlight head. Turbo
provides 100% output while user-defined users contains five selectable
sub-modes.

Turbo Mode

Turbo mode is accessed when the MT40 flashlight is switched ON and the
head lightly tightened. While in this mode, momentary illumination can be
achieved by switching off the flashlight and then half pressing and holding the
switch. Momentary illumination can be used as a flashing signal indicator or
apply to various tactical applications.

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”. Pressing
the switch all the way down will save and memorize a desired setting.

Tips: Make NITECORE MT40 your perfect multi-task flashlight.

NITECORE MT40 flashlights essentially have two modes: Turbo mode (100%
output) and custom mode. Turbo mode is accessed by tightening the flashlight
head while any of one of the four customizable modes (strobe, low, medium
and high) are selected by loosening the head and rapidly pressing the on/off
switch to cycle through the modes. A given mode can be saved by simply turn
off the light while in that mode. Real-world examples include: When used as a
flashlight around the home, the head can be loosened and low level selected in
custom mode, providing long runtimes at a lower light intensity. The same
flashlight could then be taken out and used a law-enforcement duty light, with
user-defined mode set in strobe, making it easy to alternate between turbo
mode and strobe with a simple twist of the flashlight head.

Maintenance

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