To disconnect Wave from Softwave you can:
- Turn Wave off by holding the Up and Down buttons simultaneously.
- Simply close Softwave.
- To completely disconnect Wave you can navigate to Menu->Connect Bluetooth Device and press the "x" behind the connected Wave. This way Softwave will forget Wave.
Note that Softwave has a built in auto-connect feature, so the next time you open Softwave it will connect automatically to Wave unless you do this.
