Where is ToneProfile (or similar) for API 1.2.0?

Hi guys,

I don't find the instructions to listen Beep in my Forerunner 235 with API 1.2.0.

In the documentation i found only ToneProfile with api level > 3.1.0 (developer.garmin.com/.../ToneProfile.html).

Are there anybody that to help me?
thank you very much
