Operation Instruction

Two buttons control the TK75's operation. The right side button with a power source
mark is for ON/OFF. The left side button with a recycling mark controls MODES &
BRIGHTNESS LEVELS.
A single press on the power switch turns the TK75 on or off.
With the flashlight on, a single press on the mode switch switches the light between the Turbo
→Low→Mid→High→brightness levels;
To enter into the strobe mode, press and hold the side mode switch for about one second. It
will flash between 6Hz and 15Hz every two seconds.
To enter into SOS mode, press and hold the side mode switch for about three
seconds.
While in strobe or SOS mode, a single press on the side mode switch returns the TK75 to
non-flashing mode where brightness can be adjusted.
Whether it is on or off, the light will enter into strobe or SOS mode if the mode switch is
pressed and held.
With advanced circuitry, the TK75 will remember the last-used brightness level (not flashing
modes) the next time it is turned on.
Overheating protection:
As with any high-output LED flashlight, the TK75 builds up heat when operated at Turbo
brightness for extended periods. For your safety, the light will downshift to High after 20
minutes in Turbo. Return to Turbo using the mode switch.
