I disagree with the order, but agree with the general content. Sometimes you should get shelter before anything else (for instance, sudden rain/snow storm). Stabilize the situation before you signal for help. Given Murphy's law, that'll be the time you have to change the batteries, smack the side of your toy, hold it upside down with a coat hanger in your other hand, and pray to the electronic gods. I'd rather do that under a rock or something out of the elements.
