On the AC power adaptor
•Use only the supplied AC power adaptor. If
your unit is not supplied with it, use AC-
E45HG AC power adaptor. Do not use any
other AC power adaptor.
•To unplug the AC power adaptor from the wall
outlet, grasp the adaptor itself, do not pull its
cord.
On dry and rechargeable batteries
•Do not throw the batteries into fire.
•Do not carry the rechargeable battery with
coins or other metallic objects. It can generate
heat if the positive and negative terminals of

during use as it may cause malfunction or
serious accidents.
On 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 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 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 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.
