A Tutte le auto della polizia

By the time of the series' final season, Kate Jackson was receiving the most fan mail of all cast members.

Anytime the officers are responding code 3 (lights and sirens) the sirens in the patrol cars are on wail and yelp simultaneously. In order to change the sounds on an emergency vehicle siren it must be done manually with the switches on the siren box inside the vehicle. It is impossible to have two sounds going at the same time.
