CAUTION:
THIS PRODUCT UTILIZES A LASER.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED
HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
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 pW/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 abgestrahit.
Welleniange: 780 nm
Maximale strehlungsleistung der lasereinheit: 100 uW/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 einstellregier der lasereinreit nicht verstellen.
. Nicht mit optischen instrumenten in die fokussierlinse blicken.
. Nicht Gber langere zeit in die fokussierlinse blicken.

@Do not operate the Remote Controller of this unit near a
unit which is designed to operate using a different
remote controller.
©Do not simultaneously use this Remote Controller and
one or more remote controllers intended either for the
same type of unit or for another type of unit, such as a
television set.
elf you operate the Remote Controller near the unit
when listening to an MW or LW broadcast, noise may
be heard. In such a case, hold the Remote Controller at
a sufficient distance from the unit so that noise is not
heard.
Do not disassemble the Remote Controller or touch
any of the components inside it.
Do not place a heavy object on the Remote Controller
or leave it exposed to direct sunlight or in a hot location.
©Do not spill liquids on the Remote Controller. This may
Cause damage to the controller.

Although the life of the batteries will vary depending upon
the number of times that the Remote Controller is used, the
average life based on the used of the batteries is about 1
year.
If the Remote Controller fails to operate when it is held
near the unit, replace the batteries with new ones, even if
one year has not elapsed.
