• Remove plastic battery disconnect
• Hold the light vertical with red button near your thumb
• Press the button to cycle through the 3 modes/off
• Select the mode you want and turn light horizontal (with the Clip on Top) the led should turn off
• If needed Remove the tube to adjust the tilt sensor to your tip-up.  Be gentle as the tilt switch is fragile
• Do not allow the wires of the tilt switch to rest on each other or the light will not work properly 
• When attaching to tipup the clip should be on top.  This will help ensure that the switch is at the correct angle
