INSTRUCTIONS: 
When the timer is plugged in, the timer’s dial will turn clockwise. The pointer on 
the face of the dial points to the current time of day. 
1. Locate the segments around on the outer edge of the timer’s dial. These 
segments, each representing 30 minutes, can be pushed down and away from 
the edge of the dial (try using the tip of a pen or pencil). Conversely, segments 
that have been pushed down can be easily pushed back up by hand. Be sure all 
segments are pushed up before programming. Select a time period (or periods) 
you want the appliance turned on, then push down ALL the segments that fall on 
or within that time period. For example, to have the timer turn an appliance on at 
10PM and off at 2AM, push down the segments representing 10PM and 2AM, 
and ALL the segments in between. See Figure 1. You may need to turn the dial 
clockwise to access the desired segments. 
2. Rotate the timer’s dial clockwise until the pointer on the face of the dial points 
to the current time of day. Note: Nighttime hours  
(from 6PM to 5AM) are highlighted with a blue background. 
3. Set master switch to the TIMER ON position. 

4. Plug the timer into an electrical outlet convenient to the appliance to be 
controled. 
5. Plug the appliance into the outlet on the side of the timer. Turn the appliance’s 
switch on for automatic control. The timer will not turn the appliance on if the 
appliance’s switch is off. The appliance will now turn on and off at the times you 
have set. 
Figure 1 - shows timer (with cover open) set 
to turn appliance ON at 10PM and OFF at 2AM. 
Notice ALL segments between 10PM and 2AM 
have been pushed out. Current time is 9:00 PM. 
NOTE: To override the timer and use your appliance normally, set the master 
switch to the OUTLET ON position. This will deactivate the timer’s control of th e 
appliance, but the timer’s dial will still show the current time of day. To reactivate 
the timer’s control of the appliance, turn the appliance’s switch on and set the 
timer’s master switch to TIMER ON. In case of power failure, reset the time of 
day as explained in step 2. 
DO NOT PLUG IN MORE THAN THE RATED LOAD (SEE RATINGS). To find 
total watts being used: If watts are not marked on the appliance, multiply ampere 
rating (on nameplate) by 125 volts to determine equivalent watts. For lamps with 
multiple bulbs, sum wattage on bulbs.
