How do I lock / unlock Crescendo 2?Updated 3 days ago

Once you’ve found a vibration pattern you like, you can lock your device to avoid accidentally changing the settings during play.

Hold down both the + and – buttons for 4 seconds; the buttons will then be disabled.

The light on the underside will double-flash when locking and will flash every 10 seconds to indicate the device is locked.

To unlock, hold down the + and – buttons again for 4 seconds. If you’re unsure whether the device is locked, connect it to the charger and it will automatically return to normal operation.
