2.Turn outer dial clockwise until the marker is pointing to the correct time. The clock hands will turn with the outer dial indicating the same time as the marker. NOTE - the outer dial has AM and PM settings.

SETTING NIGHT TIME MODE

1.Locate the actuators positioned around the outer dial. Inward position indicates day time mode and outer position indicates night time mode.

2.Determine the desired times that night time mode is to begin and end.

3.Position all actuators between begin and end times in the outer position.

EXAMPLE: Night Time Mode is 11:00 PM - 7:00 AM

Place the actuator at 11:00 PM to the outside position. Con- tinue placing actuators to the outside position counterclock wise around the dial to 7:00 AM. All actuators from 7:00 AM to 11:00 PM must be in the inside position.
