9.5 USB Bluetooth Adapter Multifunction Button
The USB Bluetooth Adapter includes a single button, which you can use for many purposes depending on which state the adapter is in
(e.g., waiting, active, or call-on-hold) and the type of gesture you use on the button (i.e., tap or press). Its functions and use are similar to
the multifunction button on the headset.
The button recognizes the following types of gestures:
- Tap: A short, instantly released tap (not longer than 0.8 seconds).
- Press: Press and hold the button for 1 - 3 seconds.
