Here's a pre-trip demonstration I made with one of my 2 favorite buses in the fleet from when I used to work for First Student. The cool thing about this is I didn't even have to ask for permission to do this. My boss approached me one day and asked me if I could make a pre-trip video for training purposes so I agreed.
I also wanted to point out something with the Child Check-Mate system. Only use charter mode when you are remaining on the bus. This deactivates the Theft-Mate system for 3&1/2 hours or until the next time the ignition is cycled.
