Note 1 : Attach the remote sensor of the laser power meter to a
point angled away about 10 degrees against the pickup
lens and where the maximum power is detected, so that
there will be no light reflected onto the pickup.
Note 2 : When adjusting with VRs, first turn them completely
counter-clockwise and then adjust clockwise, so that the
value to be reached is not exceeded.
Note 3 : The wave length setting of the lasser power meter is
assumed to be 780 nm.
