Troubleshooting
- Light Not Turning On: Ensure the power cable is securely connected and the power source is active. If using a battery, check its charge level.
- Inconsistent Brightness/Color: Verify that the power supply is sufficient for the desired output. Check for any obstructions to the fan or vents that might cause overheating and automatic power reduction.
- APP Connection Issues: Ensure Bluetooth is enabled on your smartphone and the Q120 light is within range. Restart both the app and the light if connection problems persist.
- Projection Attachment Jamming: If using an optional projection attachment, ensure it is not overtightened. Overtightening can cause the heated metal to expand and jam the mechanism.
