Operation Instruction
Press the tail cap switch lightly to activate the flashlight momentarily (without any press, it will be off); Press the tail cap switch completely to turn on the flashlight and lock it. Another press will unlock it and turn it off.
When the flashlight is on, a single press on the side mode switch in the front will select the brightness levels in the order of Turbo→Low→Mid→High;
Press and hold the mode switch button for about one second to enter into the Strobe. It will flash between 6Hz and 15Hz every two seconds.
Under the condition of Strobe, a single press on the mode switch button will return the flashlight to the general mode.
The flashlight memorizes the last brightness level used in the general mode even after changing the batteries (it will not remember any flashing modes). The next time you turn on the flashlight, it will light up at the last used general mode.
Overheating protection: TK15 will accumulate a lot of heat when it is working in Turbo output. To avoid overheating, the flashlight will automatically transfer into the high brightness level after working in Turbo output for over 30 minutes. If the Turbo output is needed continually, just reset it again.
