6. Operating Instructions
6.1 Basic Operation (Light and Laser)
The TLR-10 Flex features ambidextrous rear switches for easy activation. The unit offers three primary modes: LED only, Laser only, and a combined LED and Laser mode.
- Momentary Activation: Press and hold either rear switch. Release to turn off.
- Constant On: Press and quickly release either rear switch. Press again to turn off.
6.2 Mode Selection
To cycle through the available modes (LED only, Laser only, LED & Laser), press and hold one of the rear switches, then quickly tap the other switch. Repeat this action to cycle to the next mode. The device will remember the last selected mode when turned off and on again.
6.3 Strobe Mode
To activate the strobe function, quickly double-tap either rear switch (within 0.4 seconds). To turn off the strobe, press and release either switch.
6.4 Safe Off Feature
The "Safe Off" feature prevents accidental activation and conserves battery life. To engage Safe Off, rotate the light head counter-clockwise approximately 1/4 turn until it clicks. To disengage, rotate clockwise until it clicks and is fully tightened.
6.5 Laser Aiming Adjustment
The integrated red laser can be adjusted for windage and elevation. Use a small flathead screwdriver or the appropriate tool from the key kit to make fine adjustments. The adjustment screws are typically located on the side and bottom of the laser housing. Turn the screws incrementally and test the laser's point of impact until it aligns with your desired aiming point.
