SAFETY PRECAUTIONS

WARNING! Never look at the sun directly with the binoculars! Doing so may damage your eyes or cause blindness.

CAUTION!

• Do not leave the binoculars in an unstable place. They may fall and cause injury.
• Do not look through the binoculars while walking. You may walk into unexpected objects and get hurt.
• Do not swing the binoculars by their straps. They may hit someone and cause injury.
• If you use the binoculars for a long period of time, the rubber eyecups may cause skin irritation. If you experience any symptoms, discontinue use immediately and consult a doctor.
• Be careful not to pinch your finger when adjusting interpupillary distance or diopter. Be particularly careful if you let small children use the binoculars.
• Keep the polyethylene bag used for packaging out of the reach of small children. It may block their mouths and noses and cause suffocation.
• Be careful that small children do not inadvertently swallow the cap or eyecup. If it does happen, consult a doctor immediately.
• Do not disassemble the binoculars. Repair should be referred to a Nikon authorized service representative.

OPERATION PRECAUTIONS

Note
OPERATION AND CONTROLS

• Do not open the right and left binocular tubes beyond their limits. Also be careful not to rotate the diopter ring, focusing ring, and zoom lever  (ring) beyond their limits.
• Avoid rain, water splashes, sand, and mud. With waterproof/ water-resistant binoculars, though some rain or water splash will do no harm, wipe the water off as soon as possible. To confirm if your binoculars are waterproof/water-resistant or not, check the instruction manual of the product you purchased.
• Do not subject the binoculars to physical shock. If you accidentally apply strong shock or drop them and the image is not normal, or if they are submerged in water, immediately contact the dealer where you purchased them or a Nikon authorized service representative.
• If you enter a warm room from a cold outdoor environment, the lens surfaces may temporarily become clouded due to sudden temperature changes. In this case, let them dry until the moisture disappears naturally.
• The soft case, strap, and external materials utilized on binoculars and rubber eyecups may deteriorate due to aging and stain clothes. To prevent this, check their condition before each use, and consult with a Nikon authorized service representative if such deterioration is found.

STORAGE

• Water condensation or mold may occur on lens surfaces because of high humidity.
  Therefore, store the binoculars in a cool, dry place. After use on a rainy day or at night, thoroughly dry them at room temperature, then store in a cool, dry place.

• For long term storage, keep binoculars in a plastic bag or an airtight container with a desiccant. If this is not possible, store in a clean, well-ventilated place, separate from the case, as they are easily affected by moisture.

• Do not leave the binoculars in a car on a hot or sunny day, or near heat generating equipment. This may damage or negatively affect them.

MAINTENANCE & STORAGE

• Remove dust trapped in the focusing unit, diopter adjustment unit, or other rotating parts with a soft brush.
• After having removed dust with a blower, clean the body surface using a soft, clean cloth. After use at the seaside, lightly soak a soft, clean cloth with water and wipe off salt that may be on the body surface. Then wipe the body surface with a dry cloth. Do not use benzene, thinner, or other organic solvents. Note: A blower is rubber cleaning tool that strongly blows out air from a nozzle.
• When removing dust on the lens surface, use a soft oil-free brush.
• When removing stains or smudges like fingerprints from the lens surfaces, wipe the lenses very gently with a soft clean cloth. Use a small quantity of pure alcohol (ethanol) or lens cleaner available in stores to wipe stubborn smudges, from the center of the lens to the outside in a circular motion. Do not use anything hard as it may scratch the lens surface.

OPERATION

Place your eyes in the right position
Look into the eyepieces and use the binoculars in a position where vignetting does not occur (no shadows around the field of view).

Models with adjustable eyepieces
Use the binoculars in the retracted state when wearing eyeglasses, and in the extended state with naked eyes.

Adjusting interpupillary distance
Match the distance between right and left eyepiece tubes with your interpupillary distance by moving the tubes apart or closer together. Merge the two circular viewfields into one.

Diopter adjustment
(Balancing right and left eyesight)

• With the focus correctly adjusted, remember the diopter index position for easier future diopter adjustment.
• For focusing with the diopter adjustment ring or focusing ring, rotate clockwise to focus on a distant subject, or counterclockwise for a nearby  subject.

Depending on the type of binoculars, the adjustment method differs as follows.
• CF: Central focusing binoculars Binoculars with the diopter adjustment ring on the right eyepiece.

1. Rotate the focusing ring until you obtain a sharp image of your subject through the left eyepiece with your left eye.

2. Rotate the diopter adjustment ring of the right eyepiece until you obtain a sharp image of the same subject through the right eyepiece with your right eye.

3. Check focusing on both eyes.
   When you view a different subject, adjust the focusing ring until you obtain a sharp image.

Binoculars with the diopter adjustment ring on the left eyepiece (some models of zoom binoculars).

1. Set the zoom lever at the maximum magnification position.

2. Rotate the focusing ring until you obtain a sharp image of your subject through the right eyepiece with your right eye.

3. Rotate the diopter adjustment ring of the left eyepiece until you obtain a sharp image of the same subject through the left eyepiece with your left eye.

4. Check focusing on both eyes.
   When you view a different subject, adjust the focusing ring until you obtain a sharp image.

• IF: Individual focusing binoculars
For individual focusing binoculars, diopter adjustment is basically unnecessary.

1. Focus right and left eyes separately.
   Focus the right and left eyes one by one when you change the subject.

Note: For zoom binoculars
When viewing the subject at a different magnification, first correctly adjust focusing at a higher magnification. This minimizes blurring, which may occur when you change magnification.

• If you adjust the focus at a low magnification, there is more blurring when you change to a high magnification

The binoculars are used with the objective lens caps folded open (C).

Eyepiece cap
There are two ways you can position the eyepiece cap as you observe your subject.

• Remove the eyepiece cap from the eyepieces and allow it to hang from the neckstrap.
• Remove the eyepiece cap from the eyepieces, then detach the right strap from the cap and allow it to hang from the left neckstrap (C).
