Precautions
On safety
Do not put any foreign objects in the DC IN 3V
jack.
On power sources
• Use house current, nickel metal hydride
rechargeable battery, LR6 (size AA) battery,
or car battery.
• For use in your house: Use the AC power adaptor
supplied with this recorder. 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, dry battery,
rechargeable battery, or car battery cord). 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
Road safety
Do not use headphones 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 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.
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.
