Resetting the LED Light
The system comes with a default 6 month timer. To change from 6 to 12 months:
1. Hold the Reset button and watch the LED – it will go steady, then flicker, then go off for 6 seconds (continue to hold). When the LED begins to blink after about 12 seconds of holding, release the button.
2. Once the button is released, the LED will show several double blinks to indicate the 12 month timer is set.
3. Repeat this process to change back to 6 months.
