• Leave some slack in the cord of the earphones if you wind them around the unit.
• Do not disassemble, remodel, drop, or allow the unit to get wet.
• Do not use or store in locations directly exposed to sunlight, corrosive gases, a
heat vent, or a heating appliance.
• Do not use or store in humid or dusty locations.
• Do not use force to open the battery lid.

Listening caution

Do not play your headphones or earphones at a high
volume. Hearing experts advice 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. Sound can be
deceiving. Over time your hearing “comfort 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 comfortably and clearly, and
without distortion.
Once you have established a comfortable sound level:
• Leave it there.

Batteries

• Align the poles (+ and –) properly when inserting the battery.
• Do not recharge ordinary dry cell battery.
• Remove the battery if the unit is not to be used for a long time.
• Do not use batteries if the covering has been peeled off.
• Mishandling of battery can cause electrolyte leakage which can damage items
the fluid contacts and may cause a fire.
If electrolyte leaks from the batteries, consult your dealer.
Wash thoroughly with water if electrolyte comes in contact with any part of your
body.
•
If electrolyte gets into your eyes, you may lose your sight. Do not rub your eyes but wash
them with clean water, and seek medical advice immediately.
• Do not throw into fire, short-circuit, disassemble, or subject to excessive heat.
