- NICREW ClassicLED Lights
- NICREW SlimLED Lights
- NICREW Submersible Lights
- Other lights with standard 2.5mm/2.1mm power connectors.

Maintenance
The NICREW Single Channel LED Light Timer requires minimal maintenance. Keep the device clean and dry. Avoid exposing it to excessive moisture or extreme temperatures. Do not attempt to open or repair the device yourself, as this will void the warranty.
Troubleshooting
- Timer display is off: Check all power connections to ensure they are secure. Verify the power adapter is plugged into a working outlet.
- Time reset after power outage: The timer's internal memory saves programmed settings but not the current time. After a power interruption, you will need to reset the current time manually. Programmed on/off cycles will remain saved.
- Lights not dimming: Ensure your specific LED light fixture supports dimming. Some lights, like SkyLED, are not dimmable and will only operate in F2 (straight on/off) mode.
- Incorrect time display or running fast/slow: Ensure the timer is not connected in-line with another remote receiver or dimmer that might interfere with its voltage supply, as this can affect clock accuracy.
