   2. Tighten the mounting screws on the dimmer.
   3. Snap on the wallplate.

7. Turn Power On

   Restore power at the circuit breaker.

Compatible Light Bulbs

Works with energy-efficient dimmable light bulbs:

• LED: up to 150 W
• Halogen: up to 600 W
• Incandescent: up to 600 W

You can mix dimmable LEDs with halogen and incandescent bulbs. Dimmable LED performance varies; if bulbs flicker or turn off, see Step 9 'Adjusting Low-End Trim'. For a list of compatible LEDs, visit www.lutron.com/LEDfinder.

Using Your Controls

The dimmer features a slider for light level adjustment and a Front Accessible Service Switch (FASS).

To replace light bulbs: Pull the FASS out to remove power at the light socket.

Adjusting Low-End Trim

Use this to optimize performance for dimmable LED bulbs that may flicker or turn off at low levels.

1. Pull the FASS out to the open position.
2. Press and HOLD the 'Off' button.
3. Continue holding 'Off' and push the FASS back in until the light bar flashes (approx. 6 seconds).
4. Release the 'Off' button.
5. Move the slider down until it stops.
6. Slowly move the slider up until the bulbs just barely turn on.
7. Press 'Off' to save the setting.

Night Mode Ambient Light Setting

Night Mode allows the dimmer to rise to ON and fade to OFF more gently based on ambient light conditions.

1. Pull the FASS out to the open position.
2. Press and HOLD the 'On' button.
3. Continue holding 'On' and push the FASS back in until the light bar flashes (approx. 6 seconds).
4. Move the slider up or down to select the desired Night Mode setting:
   • Top Slider (HIGH): Brighter light needed to exit Night Mode. Ideal for rooms with lots of natural light.
   • Middle Slider (MEDIUM): Moderate light needed to exit Night Mode. Ideal for rooms with natural light.
   • Bottom Slider (LOW): Very little light needed to exit Night Mode. Ideal for rooms without natural light.
5. Press 'On' to save settings or 'Off' to disable Night Mode.
6. The light bar will display the saved setting and return to normal mode.

Restore Factory Settings

To reset the dimmer to its original factory settings:

1. Tap the 'On' button quickly 3 times, holding on the last press.
2. Continue to hold the 'On' button until the light begins to flash quickly.
3. Release the button.
4. Immediately tap the 'On' button 3 times and release.

The light bar will flash slowly 3 times, then turn off. All settings will be returned to factory defaults.
