Precautions
On safety
Do not put any foreign objects in the
DC IN 4.5 V jack.
On power sources
• Use three size AA (LR6) batteries,
the house current, or a lithium ion
rechargeable battery.
• For use in your house: Use the AC-
E45HG AC power adaptor (not
supplied). 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 (dry
batteries, AC power adaptor, or a
rechargeable 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 to cool
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 injury.

Additional information
While carrying the recorder
Keep personal credit cards using
magnetic coding or spring-wound
watches, etc., away from the recorder
to prevent possible damage from the
magnet used for the speaker.
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
• Do not break open the shutter.
• Do not place the cartridge where it
will be subject to light, temperature,
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.
