The Sylvania SA 300 is an industrial digital timer for lights and appliances. When you enter your area code into the timer, it adjusts year-round to sunset. It turns devices on at sunset and off after a specified amount of time. The digital timer also offers the option of turning off the automated zip-code-based timing and setting up to four manual times of your choice.
Turn the power off at the circuit breaker or the fuse box.

Setting the Area Code
Press the "Mode" button until "ZIP" appears.
