There are three reasons why iHere beeps
1) iHere beeps once when it first connects and whenever it reconnects to the iHere3 app. Reconnecting happens when the previously out of range iHere comes back into range of your Apple device. This beep cannot be deactivated.
2) iHere beeps when you click on the "Find" button on the iHere3 app to find the device that's attached to your keys, wallet or purse.
3) iHere makes a series of beeps to alert you when the iHere and your device have separated, suggesting you have left your device behind called the separation alarm. This can be deactivated within the setting in the app.
