Setting Minimum Light Level (Programming mode)
1. Ensure the dimmer is set to the OFF position.
2. Set the bulb selector switch to the LED/Incandescent position.
3. Push rocker switch to ON position.
4. Set the bulb selector switch to the CFL position.
5. Raise or lower the slide control level to achieve the desired minimum
light level.
6.
Set the bulb selector switch back to LED/Incandescent position.
7. A momentary flash of the bulb will occur confirming the new setting.
8. Push rocker switch to the OFF position.
9. For dimmable CFL lamps you must return the bulb selector to the CFL
position.
Dimmer Bulb Selector Switch:
Cat. No. 6674-P is pre-set at the factory with the bulb
selector switch set to LED/Incandescent. For CFL bulb
applications the switch should be moved to the position
marked CFL. The lamp selector slide switch is also used to
adjust the minimum light level when dimming. Information on
this feature is found under OPERATION.

Step 9
NOTE: If using the dimmer in a 3-way application, the lights will turn ON
at brightness set on dimmer's slide control lever. The lighting level can be
controlled from the dimmer location and can be switched ON/OFF from
either the dimmer or switch location.
LED/Incandescent Mode: The selector switch is pre-set at the factory
to this mode. Use this mode for dimmable LED bulbs and incandescent/
halogen bulbs. To avoid flickering at the low end of the dimming range you
can pre-set the minimum light level. See OPERATION to manually program
the minimum light level.
CFL Mode:
To be used for dimmable CFL bulbs only. In this mode the dimmer
provides a pre-set kick-start to aid the lamp in starting. To avoid flickering at
the low end of the dimming range you can pre-set the minimum light level. See
OPERATION
to manually program the minimum light level.
