m™ PRECAUTION OF LASER DIODE
CAUTION:
This
product
utilizes
a
laser
diode
with
the
unit
turned
“on”,
invisible
laser
radiation
is
emitted
from
the
pick
up
lens.
Wave length: 780 nm
Maximum output radiation power from pick up: 100 ujW/VDE
Laser radiation from the pick up lens is safety level, but be sure the followings:
. Do not disassemble the optical pick up unit, since radiation from exposed laserd diode is dangerous.
. Do not adjust the variable resistor on the pickup unit. It was already adjusted.
. Do not look at the focus lens using optical instruments.
. Recommend not to look at pick up lens for a long time.

ACHTUNG:
Dieses
produkt
enthalt
eine
laserdiode.
Im
eingeschalteten
zustand
wird
unsichtbare
laserstrahlung
von
der
lasereinheit
abgestrahlt.
Wellenlange: 780 nm
Maximale strehlungsleistung der lasereinheit: 100 upW/VDE
Die strahlung an der lasereinheit ist ungefahrlich, wenn folgende punkte beachtet werden:
Die lasereinheit nicht zerlegen, da die strahlung an der freigelegten laserdiode gefahrlich ist.
Den werksseitig justierten einstellregler der lasereinreit nicht verstellen.
Nicht mit optischen instrumenten in die fokussierlinse blicken.
Nicht uber langere zeit in die fokussierlinse blicken.
