It works at low temps. Every so often during the winter I forget and leave my ipod in the car, and sometimes the temps are below zero. It still functions fine. I'm sure it's bad on the hardware to use it when it's that cold, but it still works.
Since you mentioned your pager costs $450, I'm going to take a shot in the dark and assume you have either a Motorola Minitor III or IV pager. Both of these pagers have a vibrate mode and an earphone jack. When you're in a place such as a theater where you might disturb someone, you could just plug an earphone in. Another idea would be to request a Minitor IV pager with the stored voice option, which can be set to vibrate and silently record the page for later playback.

GMRS licenses are only granted to individuals, and only cover the individual's immediate family.
FRS sounds like the way to go though, especially in a high school theater setting.
