zz Please follow the precautions below when using batteries.
Not doing so may result in overheating, generation of smoke, ignitions,
battery leakage, and explosions which may lead to fire or personal injury.
1. Be sure not to use batteries with a nominal voltage rating of 3.0V or higher
or batteries which have no nominal voltage information.
2. Make sure that the battery polarity is correct.
3. Be sure not to use any battery that is leaking.
4. Remove the batteries if anything unusual happens, such as smoke or
unusual odors being emitted.
5. Do not attempt to disassemble batteries, charge the batteries (except for
rechargeable batteries), leave batteries in a hot place, short circuit the

Precautions for Use (Please be sure to read before use)
Caution (regarding the binoculars)
Details pertaining to risks that may result in injury or damage to other objects.
zz Do not place the binoculars on an unstable surface. Doing so may cause the
binoculars to fall and could result in a personal injury.
zz Do not use the binoculars while walking. Doing so may cause you to collide
into objects or fall down and could result in a personal injury.
zz Do not swing the binoculars around by the strap. Doing so may cause the
surrounding people to be hit by the binoculars and could result in a personal
injury or damage.
zz Fingers may be pinched when adjusting the width of the binoculars. Be aware
of this when the binoculars are being used by small children.
zz If damaged, do not touch the damaged portion or inside the product.
zz Do not wet, or allow liquids or foreign objects to enter.
zz Do not store the product in very hot or cold places. The product itself will heat
or cool, possibly causing burns or other injury when touched.

eyecups may irritate the skin around the eyes. If you suspect that this may
have occurred, please see a physician.
Caution (regarding the batteries)
Details pertaining to risks that may result in injury or damage to other objects.
zz Please remove the batteries when not using the binoculars. If the batteries
are left inside, leakage may lead to malfunction, staining, or fire.
zz In the event that liquid from the inside of the batteries leaks out and contacts
your skin, be sure to wash the liquid off thoroughly. Also, do not rub your eyes
or mouth using any hand that made contact with liquid from the batteries.
If eyes or mouth are exposed to the liquid, thoroughly rinse in clean, cold
water and seek medical attention immediately.
zz When removing or disposing of batteries, insulate the contacts by covering
them with tape, as contact with other metals may cause fire or rupturing.
Precautions for Use (Please be sure to read before use)
Handling Precautions
zz Obey any instructions that prohibit the use of this product in certain places.
zz Binoculars are precision instruments. Do not use force on them, drop them,
or subject them to severe shock or vibration. Also, do not disassemble or alter
zz Do not store the binoculars in a car or similar location under direct sunlight.
Doing so will cause the binoculars to reach a temperature higher than
expected which may cause damage to occur.
zz Do not use or store them in a humid, smoky or dusty environment.
Storing the binoculars in a humid location may cause fungus to form on the
lenses or cause the lenses to become cloudy. If the binoculars are not to be
used for an extended period, clean the lenses and body thoroughly and store
in a well-ventilated dry place.
zz The binoculars are not waterproof. Avoid exposing the binoculars to rain or
water spray.
If the binoculars come into contact with water, dry them with a dry, clean
cloth. If dirt, dust or salt adheres to them, wipe them well with a clean, wellwrung wet cloth.
If water gets onto or into the binoculars, or you think dirt, dust, salt, etc. may
have gotten in, promptly take the binoculars to a service center.
zz Do not use any organic solvent, such as alcohol, thinner, or benzene when
wiping the lenses or body.
If the lens is dirty, first use a blower brush to remove dust, etc., from the lens
surface. Then use a soft, dry cloth and wipe the lens gently without scratching it.
zz If the binoculars are taken from a cold environment to a warm one,
condensation may develop on the surface and internal parts due to the
sudden change in temperature. To prevent condensation, first put the
binoculars into an airtight plastic bag before taking it to a warm environment.
Let it gradually adjust to the warmer temperature, then take out the
binoculars. Do the same when taking the binoculars from a warm
environment to a cold one.
