Getting started
Listening caution
Do not play your headphones or earphones 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 discontin-
ue 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.
Sound can be deceiving. Over time your hearing “com-
fort level” adapts to higher volumes of sound. So what
sounds “normal” can actually be loud and harmful to your
hearing.
Guard against this by setting your equipment at a safe
level BEFORE your hearing adapts.
To establish a safe level:
≥Start your volume control at a low setting.
≥Slowly increase the sound until you can hear it comfort-
ably and clearly, and without distortion.
Once you have established a comfortable sound level:
≥Leave it there.

≥You can recharge the batteries about 300 times. They
have reached the end of their useful life if play time dra-
matically reduces after recharging.
≥Play time may be shorter than usual after recharging
batteries for the first time or after they have been
unused for a long time. Repeatedly recharge and
discharge the batteries if this occurs to restore them to
normal.
∫ Care
To prevent battery damage, electrolyte leakage, and
short-circuiting, heed the following points.
≥Do not peel off the covering on batteries and do not use
if the covering has been peeled off.
≥Align the poles + and - correctly when inserting the
batteries.
≥Do not mix different types of batteries or old and new
batteries.
≥Remove the batteries if you do not intend to use the unit
for a long time.
≥Do not throw into fire, short-circuit, disassemble, or
subject to excessive heat.
≥Do not attempt to recharge dry cell batteries.
≥Do not allow metal objects to touch the battery termi-
nals as this may cause short-circuiting which is dan-
gerous.
≥When carrying batteries in a pocket or bag, ensure no
metal objects such as necklaces are placed together
with them. Contact with metal may cause short-
circuiting which can cause a fire.
