Additional information
Precautions
On safety
Do not put any foreign objects in the DC IN 3V
jack.
On power sources
• Use house current or LR6 (size AA) battery.
• For use in your house: Use the supplied AC
power adaptor or the optional AC-E30HG. Do
not use any other AC power adaptor since it
may cause the recorder to malfunction.
• The recorder is not disconnected from the AC
power source (mains) as long as it is
connected to the wall outlet, even if the
recorder itself has been turned off.
• If you are not going to use this recorder for a
long time, be sure to disconnect the power
supply (AC power adaptor or dry battery). To
remove the AC power adaptor from the wall
outlet, grasp the adaptor plug itself; never pull
the cord.
On heat build-up
Heat may build up in the recorder if it is used
for an extended period of time. In this case,
leave the recorder turned off until it cools down.
On installation
• Never use the recorder where it will be
subjected to extremes of light, temperature,
moisture or vibration.
• Never wrap the recorder in anything when it is
being used with the AC power adaptor. Heat
build-up in the recorder may cause
malfunction or damage.
On the headphones/earphones
Road safety
Do not use headphones/earphones while
driving, cycling, or operating any motorized
vehicle. It may create a traffic hazard and is
illegal in many areas. It can also be potentially
dangerous to play your recorder at high volume
while walking, especially at pedestrian
crossings. You should exercise extreme caution
or discontinue use in potentially hazardous
situations.
Preventing hearing damage
Avoid using headphones/earphones at high
volume. Hearing experts advise against
continuous, loud and extended play. If you
experience a ringing in your ears, reduce the
volume or discontinue use.
Caring for others
Keep the volume at a moderate level. This will
allow you to hear outside sounds and to be
considerate of the people around you.
On the MiniDisc cartridge
• When carrying or storing the MiniDisc, keep
it in its case.
• Do not break open the shutter.
• Do not place the cartridge where it will be
subject to light, extreme temperatures,
moisture or dust.
• Attach the supplied MD label only in the
space designated for it on the disc. Do not
stick it on any other disc surface.
On cleaning
• Clean the recorder casing with a soft cloth
slightly moistened with water or a mild
detergent solution. Do not use any type of
abrasive pad, scouring powder or solvent such
as alcohol or benzene as it may mar the finish
of the casing.
• Wipe the disc cartridge with a dry cloth to
remove dirt.
• Dust on the lens may prevent the unit from
operating properly. Be sure to close the disc
compartment lid after inserting or ejecting an
MD.
• To obtain the best sound quality, use a dry
cloth to wipe the plugs of the headphones/
earphones. Dirty plugs may cause sound
distortion or intermittent breaks in the sound.
