Handling Precautions
- Obey any instructions that prohibit the use of this product in certain places.
- 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 them.
- 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.
- 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.
- 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, well-wrung 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.
- 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.
- 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.
