6. Maintenance

The Legrand Radiant dimmer requires minimal maintenance.

• Cleaning: To clean the dimmer and wall plate, wipe with a soft, damp cloth. Do not use abrasive cleaners or solvents.

7. Troubleshooting

If you experience issues with your dimmer, refer to the following common problems and solutions:

• Lights are flickering: This is often due to incompatibility with the LED bulb or incorrect dimming range settings. Use the calibration button to adjust the high-end and low-end dimming limits. Ensure your LED bulbs are dimmable.
• Lights do not turn on or off: Verify that power is supplied to the dimmer at the circuit breaker. Check all wiring connections for tightness. Ensure the dimmer is compatible with your light fixtures (not for 0-10V LED drivers).
• Lights have a delayed turn-on or 'pop-on' effect: Activate the optional LED Burst Mode setting as described in the full installation guidance.
• Dimmer is warm to the touch: It is normal for dimmers to feel warm during operation. If the dimmer becomes excessively hot or emits a burning smell, immediately turn off power at the circuit breaker and contact a qualified electrician.
