On 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 some areas. It can
also be potentially dangerous to play your
headsets at high volume while walking,
especially at pedestrian crossings. You should
exercise extreme caution or discontinue use in
potentially hazardous situations.
Preventing bearing 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 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 to the people around you.
On the water resistance

be sure to wipe off water, dust or sand on the
exterior of the unit. Open and close the lid
where water or sand cannot fall in the unit, and
make sure that your hands are diy. If water or
sand falls in the unit, trouble may occur.
• When closing the lid, check that there is no dust
or sand on the rubber packing around the lid.
Then close the lid firmly with the buckle.
• The supplied headphones 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.

the player near water during AC opetation.
• Cover the DC IN 4.5 V jack and 0 jack with the
