Pilottone

Pilottone is a sound that is used to control things like telephones or radios. When you press a button or make a noise, it sends out a special sound that tells the other device what to do. It's like speaking a secret language that only the phone or radio can understand.

Think of it like playing a game of Simon Says. When you say "Simon says touch your toes," everyone knows to touch their toes. Pilottone works the same way, except instead of talking, you make a special sound to make something happen.

So, the next time you use a phone or radio, remember that the pilottone sound is what makes it work!
