The pagers were designed and marketed as system devices for agencies. The scanner community using them as receivers is no different that using a Motorola or Harris radio for NAS. As such, I agree with Kevin. If my fire agency lost one, I would want the ability to shut it off especially if its keyloaded.
For those asking, the devices can respond to not only QC2 paging, but call alert as well which requires a unique ID.
Treat these devices as you would any other professional system radio. I know the ranges of IDs in use on my local system and try not to pick an ID that is commonly used to illegally access a system (ID 1 for example) or put it in the range(s) that my local systems use. Any ID can be hit of course, but with 16.7 million to choose from, you can surely pick one that is lower risk that others.
