Precautions
On safety
• Do not put any foreign objects in the DC IN
3V jack.
• Keep the terminals on the recorder away from
metallic objects or surfaces. Such contact may
short-circuit the terminals and cause
dangerous heat generation.
On water resistance
• Before opening or closing the buckle, be sure
to wipe off water, dust or sand on the exterior
of the unit. (The unit is not water-resistant
with the upper lid open.)
• Since water in the headphones/earphones jack,
the USB connecting jack, LINE IN
(OPTICAL) jack, or DC IN 3V jack may
cause rust, cover them with the attached
rubber caps when the jacks are not in use.
• Since the unit is airtight, you may not be able
to open disc lid because of sudden change in
air pressure inside the unit, which happens
after being transported on a plane or moving
from a warm place to a cold place. To open the
lid in this case, pull off the rubber cap that
covers the DC IN 3V jack, and then open the
lid. After you open the lid, make sure to cover
the jack with rubber cap again.
• The supplied headphones/earphones are not
meant to be immersed in water or come in
continuous contact with water. If they are
accidentally dropped into water or get wet, dry
them with a soft cloth. Never use an electric
hair dryer.
• If the unit or the headphones/earphones are
immersed in salt water, be sure to wash them
in non-running fresh water. Never wash them
under running water, and never use soap or
detergent.
• Any sand or dust on the rubber packing will
prevent the lid from closing tightly, and water
may leak in. Brush off the dust once in a
while.
• We recommend the packing to be changed
every year. Change the packing at an
authorized Sony Service Facility.
On power sources
• Use house current, LR6 (size AA) 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, 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/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.
