Dang if you were closer I would send you to my guy, he could get it set up to work with a vibrate setting.
I have the Minitor III and a V, both are set up the same.
Did the fire department set you up with it?
I would get in contact with the place they got it from. I bet it wasn't set up right.
Mine has 4 channels
#1 Repeater
#2 Repeater (Vibrate)
#3 Direct
#4 Scan
Normally keep it on scan and I hear all the pages for the county and get to listen to the road crew.
Warning about the vibrate setting, if your not ready for it it will scare you.

Got one of my guys and he almost fell off of his tractor; was a pager test. :lol2:
