Notes 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 many areas. It can also

be potentially dangerous to play your headphones 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 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

people around you.

Warning

If there is lightning when you are using the unit, take

off the headphones immediately.

Do not Immerse in Water

This product is designed to be splash-resistant, but

should not be immersed in water or come in

continuous contact with water.

• Before installing the battery, be sure to wipe off

drops of water on the unit.

• The supplied headphones are not meant to be

immersed

in water or come in continuous contact with water.

If they get wet, dry them with a soft cloth.

Never use an electric hair dryer while wearing the

headphones.

Notes on the Clock

• The clock’s digital display may become dim when

exposed to heat. It will recover when the

temperature returns to normal.

• When exposed to excessively high or low

temperature (for example, in a car), the flashing of

digits on the clock’s display may become slower.

• In a poorly lit place, the clock’s display may become

dim.

• Do not put the unit where its clock controls may be
