The wash and rinse temperature selections are self-explanatory. You would always want to select a cold rinse for the PERMA PRESS cycle.
The water level selections you will need to learn, as they generally are not the same among the various manufacturers. One way to do this would be to fill the tub while it is empty. Set to SMALL and let it fill. When it stops filling, turn the knob to RESET and then back to MEDIUM. Repeat this two more times for LARGE and EXTRA LARGE. It appears that your machine has infinite water level settings, which means you can set it somewhere in between for just the right amount of water, but again, you will need to learn how high these various settings fill the tub.
For speed selection, NORMAL will provide fast agitation/spin and DELICATE will provide slow agitation/spin. The PERMA PRESS setting probably provides fast agitation and slow spin.
The cycle selector dial is poorly marked. I've never heard of a soak at the end of a wash sequence, but that appears to be the case on your machine. It's likely just the deep rinse cycle that can be used as a manual soak sequence if desired. The main difference between the REGULAR cycle and PERMA PRESS cycle probably involves a partial first drain and refilling with cold water for the cool-down portion of the PERMA PRESS cycle. Other than that, it appears that the REGULAR cycle provides a longer wash period for heavily soiled items. I have rarely used the PERMA PRESS cycle on any washer I've owned. REGULAR uses less water.
The good thing about your washer is that it allows you to select the speeds rather than programming them in to the cycle. This gives you more flexibility in how you use the cycle options.
