How do you set upm model dt 420 electronic timer

Open UPM DT420 manual on following link:

The manual is longer than allowed for free answer and has important illustrations and options.
Please read the manual in addition to instructions given below.

Copied directly from the manual:
1) Select AUTO using the slide switch
2) Select the desired On-period (2, 4, 6, 8, 10 hours) using the dial switch
3) For continuous Dusk to Dawn operation, Select CONTINUOUS using the dial switch.
Timer turns ON automatically at dusk and turns off according to how you set 1 2 and 3.
If timer does not operate, or if it turns on at odd times, then it is broken.

Note: UPM manuals normally leave out important information, but this particular instruction matches closely with similar products and is probably accurate.
