servicing should be referred to autho-
rized service personnel.

AC adaptor
This AC adaptor operates on AC between
100 V and 240 V.

Precautions for Listening
with the Headphones or
Earphones
≥Do not play your headphones or ear-
phones at a high volume. Hearing experts
advise against continuous extended play.
≥If you experience a ringing in your ears,
reduce volume or discontinue use.
≥Do not use while operating a motorized
vehicle. It may create a traffic hazard and
is illegal in many areas.
≥You should use extreme caution or
temporarily discontinue use in potentially
hazardous situations.
≥Even if your headphones or earphones are
the open-air type designed to let you hear
outside sounds, don’t turn up the volume
so high that you can’t hear what’s around
you.
Installation
1. Water and Moisture—Do not use this
unit near water—for example, near a
bathtub, washbowl, swimming pool, or
the like. Damp basements should also be
avoided.
2. Condensation—Moisture may form on
the lens in the following conditions…
1. ≥immediately after a heater has been
turned on.
1. ≥in a steamy or very humid room.
1. ≥when the unit is suddenly moved from a
cold environment to a warm one. If
moisture forms inside this unit, it may
not operate properly. To correct this
problem wait about one hour for the
moisture to evaporate.
3. Heat—Use the unit within its operating
range (5 oC to 35 oC). Use beyond this
range can cause the protection circuitry
to function and render the unit inopera-
ble. Never use or place near a heat
source or leave in an automobile ex-
posed to direct sunlight as this may
deform the cabinet and cause mal-
function.
4. Foreign Material—Care should be
taken so that objects do not fall into and
liquids are not spilled into the unit. Do not
subject this unit to excessive smoke,
dust, mechanical vibration, or shock.
Service
1. Damage Requiring Service—The unit
should be serviced by qualified service
personnel when:
1. ≥The AC mains lead or AC adaptor is
damaged.
1. ≥Objects have fallen or liquid has spilled
into the unit.
1. ≥The unit has been exposed to water.
1. ≥The unit does not appear to operate
normally or exhibits a marked change
in performance.
1. ≥The unit has been dropped, or the
enclosure damaged.
