Don't forget to press the home button and press shift + delete. No one told me this so basically I never correctly sent RF messages for the first month was wondering why my open time requests were never processed.

So press the home button, then shift + delete, then **** + delete again. You see that the RF message will start out with HI0/HTL2/52AE. Then press tab skip to the next blank to type. Then at the end tab to "send" press enter and then you should get a "done" message.
