Because this unit uses the optical magnetic recording, the unit outputs over 10
times more laser than a CD player does. In the adjustment mode, the laser is
always being output. Therefore, be especially careful not to look laser beam
directly or to touch the laser beam when adjusting the unit and checking its
operation.
