Example 3: PB7 activates which starts message7 playing. This message will continue playing as long as
PB7 remains active. CC1 goes active, its timer starts, CC1 is a higher priority message, so message1 is
heard instead of message7 now. CC1 remains active through the 10 minute timer and the timer times out
shutting off message1. Message7 starts playing again at this time because PB7 is still active.
The addition of the timeout functionality in the SP40S-D firmware causes the user interface on the SP40S
to indicate that a particular DV input is in timeout.
