This article will explain you how to use Triby's button and understand its menus.
To access Triby's menus, simply press both List buttons (...) on either side of the screen at the same time.
Now that you've entered the menu, you can scroll through menu options by using the Radio buttons. The button on the top (Radio button #1) scrolls up, while Radio button #2 scrolls down.
To select, press the List button (...) on the right side of your Triby (yellow square), just beneath the Radio buttons. To cancel a selection or go back, press the List button (...) on the left side of your Triby, just beneath the Phone buttons (purple square).
