You can go ahead and set the power switch to the center position, unless you wish to lock the keys.
If you have a recurrence of this bizarre “voice is missing” sound, be sure that the headphone jack is fully inserted. The Fuze requires a little more pressure, as it has a tight jack.
What you may be hearing is a differential signal between the left and right channels, caused by an open ground connection.
