Police Walkie Talkie Sound Message - Tone Link
This long guide explains the common sound/message tones used with police and other public-safety walkie-talkies (two-way radios), how they’re used operationally, technical standards and signaling methods, integration with radio systems, legal/privacy considerations, and practical steps for implementing or simulating tones for training, dispatch, or interop testing. Assumptions made: “police” refers to public-safety radio systems in the U.S. and similar North American/International practices where applicable; some systems and legalities vary by jurisdiction. Where specifics vary, the guide gives alternatives and safe defaults.

Weird how the US never got these commercials despite being filmed here. Guess they hear assumed it was too weird for American sensibilities. Personally, I love it.
I think Pepsiman was also in the Japanese version of the Saturn port of a fighting game called Fighting Vipers as well.
