WARNING

24 Hour Outdoor Timer Instructions:

1. Locate the segments around the outer edge of the timer’s dial. These 

segments, each representing 15 minutes, can be pushed out and away from 

the edge of the dial (try using the tip of a pen or pencil). Conversely, segments 

that have been pushed out can be easily pushed back in by hand. Be sure all 

segments are pushed in before programming. Select a time period (or periods) 

you want the appliance turned on, then push out 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 out 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: daytime hours (from 6:30AM to 6:30PM) are 

highlighted with a black background.

3. Set Timer / On switch to the 

TIMER position. Make sure to push switch fully to 

timer position you will feel the switch snap into place.

4. Plug the timer into an electrical outlet convenient to the lights to be controlled.

5. Plug the lights into the outlet on the bottom of the timer. Make sure that the 

light is turned on. The lights will now turn on and off at the times you have set.

NOTE: To override the timer and use your lights normally, set the Timer / On 

switch to the 

ON position. This will deactivate the timer’s control of the lights, but 

the timer’s dial will still show the current time of day. To reactivate the timer’s 

control of the lights set the timer’s Timer / On switch to 

TIMER. In case of power 

failure, reset the time of day as explained in step 2.

Not for permanent installation. Do not install or use this product for more 

than a 90 day period per year. When used outdoors, plug only into a GFCI 

protected receptacle. Receptacle should be mounted in an approved 

“weatherproof while in use” type outlet box.
