This indication alerts you to the fact that any improper use ignoring the contents described herein can result in potential injury or material loss.

SAFETY AND OPERATION

PRECAUTIONS

Warning

•Never look at the sun directly using the Fieldscope.

Cautions

•Avoid rain, water splashes, sand and mud.

•Do not operate focusing ring if exposed to water or rain.

•Do not disassemble the Fieldscope.

•Do not swing the Fieldscope by its strap. You could hit someone and cause injury.

•Take care not to pinch your finger when sliding the lens hood back.

•Do not leave the Fieldscope in a car on a hot or sunny day, or near heat generating equipment.

•When the Fieldscope is exposed to sudden temperature changes, water condensation may occur on lens surfaces.

•Do not use alcohol for cleaning the main body.

•Do not leave the polyethylene bag used for packaging within the reach of small children.

•When carrying the Fieldscope, place inside the stay-on case.

CARE AND MAINTENANCE Lens surfaces

•Fingerprints, dust and dirt on the lens may distort viewing.

•To remove fingerprints or dirt, gently wipe the lens surfaces with a soft, clean cotton cloth or a highquality oil-free lens tissue. Use a small quantity of pure alcohol (not denatured) to wipe stubborn smudges. Do not use velvet cloth or ordinary tissue, as it may scratch the lens surface.

•Remove dust with a soft oil-free brush.

Main body

•Remove dust from the focusing ring with a soft brush.

•Clean the body surface with a soft, clean cloth and a neutral cleansing agent. Then wipe with a dry cloth. Do not use benzene, thinner, or other organic agents because they may cause discoloration or rubber degeneration.

Heat and humidity

•Water condensation or mold may occur on lens surfaces because of high humidity. Therefore, store the Fieldscope in a cool, dry place.

After use on a rainy day or at night, thoroughly dry it at room temperature, then store it in a cool, dry place.

•Do not leave the Fieldscope inside a car on a hot or sunny day, or near heat-generating equipment. This may damage or negatively affect performance.

To keep your Fieldscope in excellent condition, Nikon Vision recommends regular servicing by an authorized dealer.

1	Operation
	Mounting on a tripod (regular type for camera)

•The Fieldscope is designed to be used with a tripod. Align the screw of the tripod with the tripod mount of the Fieldscope, and firmly tighten the screw. Choose a solid tripod of medium size or larger, that can stand the weight of the Fieldscope wind pressure, as well as being vibration-free.

2 Objective lens cap (snap-on type)

•Before use, remove the objective lens cap from the objective tube.

•When not in use, snap the cap onto the objective tube.

3 Lens hood

(Fig. 1)

•To avoid diffused reflection in backlit conditions, prevent water droplets on the objective lens and to protect it, slide the lens hood outward until it stops.

•To retract the lens hood, slide the lens hood in toward the body until it stops. After the lens hood has been fully retracted, re-attach the objective lens cap to the objective tube.

4 Attaching the SEP-25, SEP-38W or SEP-20-60 eyepiece.

•Remove the mount cap, which protects the lens mount.

•To attach the eyepiece, align the index marks on the eyepiece and the main body. Next, insert the eyepiece into the mount and turn counterclockwise until you hear it “click.” (Fig. 2)

•To remove the eyepiece lens, turn the eyepiece clockwise while pushing the release button on the main body. (Fig. 3)

*Spotting Scope RAIII eyepieces (Bayonet type) can be used with the PROSTAFF 5 Fieldscope.

Operation

Eyepiece cup

(Fig. 4)

The SEP-25, SEP-38W and SEP-20-60 eyepieces are all equipped with a turn-slide type rubber eyecup.

Eyeglass wearers should always turn the rubber eyecup clockwise to use in the fully retracted position.

For those who do not wear eyeglasses, turn the rubber eyecup counterclockwise to use in the fully extended position.

•Find the target subject with your eyes, then position the objective lens toward it to look through the eyepiece with one eye.

•When targeting the subject, the aiming line on the hood is useful to take an approximate sight.

•

Water-resistant models (Eyepiece lens with main body.):

In normal use, there will be no water penetration (As tested by water equivalent to more than 1mm per minute, falling from a height of more than 200mm for a duration of 10 minutes).

Drops of water and other types of moisture will not damage the Fieldscope, but be sure to observe the following during use:

1.The unit is neither waterproof nor airtight, so it should not be held under running water or used in rainy conditions.

2.Movable parts (focusing knob, eyepiece, etc.) of the Fieldscope should not be adjusted in wet conditions. If you notice moisture has accumulated on the product’s surface, gently wipe it off immediately.
