General Description

The radio receives audible warning requests via the class 2 serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. The Multifunction Alarm generates the audible warnings on vehicles with RPO ULS - Radio Delete Option. The following lists the audible warning priority and the pulse rate:
1. Fast rate chime at 200 pulses per minute
2. Medium rate chime at 150 pulses per minute
