Easy to use, simplistic timer for running your transformer.
Move the blue tabs on the dial outward to turn on, and inward to turn off. Each segment represents 15 minute intervals and there are a total of 96 tabs- representing 24 hours in a day. Before using the timer, it is best to push in all the tabs around the timer dial. You may then pull each 15 minute segment towards the outside of the dial for the times that you want the timer to turn on.
Setting the current time:
Now that you have set the time that you want the timer to switch on or off, you need to set the current time of the day by turning the dial clockwise until the current time of the day is set against the arrow-head.
