Make sure the battery is plugged into the ChatBox 40:
Some facilities will unplug their batteries from the ChatBox 40 if they are going to sit for an extended period of time with no use (summer break). Remove the single screw from the battery door on the back of the ChatBox and confirm that the battery is plugged in.
May be time for a new battery:

The battery will need to be unplugged and a new battery inserted. Contact Saltillo for a replacement battery, part # BA007.
