Precautions
CAUTIONS BEFORE USE
Thank you for purchasing a Nikon Fieldscope.
Please observe the following guidelines strictly so you can use the equipment properly and avoid potentially hazardous problems. Before using this product, read thoroughly the "SAFETY PRECAUTIONS,"
"OPERATION PRECAUTIONS" and instructions on correct usage accompanying the product. Keep this manual within reach for easy reference.
WARNING
This indication alerts you to the fact that any improper use ignoring the contents described herein can result in potential death or serious injury.
CAUTION
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 through the Fieldscope.
CAUTION!
- This product is waterproof, however, 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. It may hit someone and cause injury.
- Do not leave the Fieldscope in an unstable place. It may fall and cause injury.
- Do not look through the Fieldscope while walking. You may walk into something and get hurt.
-
Do not leave the Fieldscope in a car on a hot or sunny day, or near heat-generating equipment.
-
If 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.
- Be careful that small children do not inadvertently swallow the cap or eyecup. If it does happen, consult a doctor immediately.
- If using the rubber eyecup for a long period of time, some people may suffer skin inflammation. If any symptoms occur, consult a doctor immediately.
Operation Precautions
CARE AND MAINTENANCE
Lenses
- When removing dust on the lens surface, use a soft oil-free brush.
- When removing stains or smudges like fingerprints from the lens surface, wipe the lenses very gently with a soft clean cotton cloth or quality 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. Once the cloth has been used for cleaning the body, it should not be used again for the lens surface.
Cleaning ED lens
- Do not use an aerosol-type lens cleaner for cleaning the Fieldscope's objective lens. The quick freezing effect of liquefied gas may break the lens.
Main body
- Remove dust from the focusing ring with a soft brush.
- Clean the body surface with a soft, clean cloth and a dry cloth. Do not use benzene, thinner, or other organic agents because they may cause discoloration or rubber degeneration.
Storage
• Water condensation or mold may occur on the lens surface 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 in a cool, dry place.
- Do not leave the Fieldscope in a car on a hot or sunny day, or near heat-generating equipment. This may damage or negatively affect it.
WATERPROOF MODELS
The EDG Fieldscope is waterproof, and will suffer no damage to the optical system if submerged or dropped in water to a maximum depth of 2 meters for up to 10 minutes.
The EDG Fieldscope offers the following advantages:
- Can be used in conditions of high humidity, dust and rain without risk of damage.
- Nitrogen-filled design makes them resistant to condensation and mold.
When using the EDG Fieldscope, observe the following: - The unit should not be operated nor held in running water.
- Any moisture should be wiped off before adjusting movable parts (focusing knob, eyepiece, etc.) of the Fieldscope to prevent damage and for safety reasons.
To keep your EDG Fieldscope in excellent condition, Nikon Vision recommends regular servicing by an authorized dealer.

Attaching a screw-in type Fieldscope eyepiece to an EDG Fieldscope with the EMA-1.
Note: It may be quite hard to screw in because of the retention of the O-ring, so ensure that it is screwed in tightly.
Take care to do this, because if the EMA-1 is not screwed in tightly enough, it will not be airtight.

Insert the FSA-L2 into the EDG Fieldscope aligning the inserter/ejector indexes of both sides.
2 Screw in the FSA-L2 in the direction of the arrow until you hear a click.
③ Attach the camera to the FSA-L2, aligning the camera inserter/ejector indexes. Loosen the clamp screw first. Then align the two camera position indexes, and tighten up the clamp screw to make the camera position horizontal.

| Compatible digital cameras: | D3 series, D2 series, D5000, D700, D300, D100, D90, D80, D70 series, D60, D50, D40 series (as of May 2009)When using a Nikon FX-format camera, vignetting occurs with focal length display between 500mm and 750mm. |
| Shooting modes: A (Aperture-Priority Auto) | mode or M (Manual) modeAppropriate aperture using aperture-priority auto mode with film camera has not been verified. |
| Exposure metering: Center-weighted metering | |
| Matrix metering and spot metering cannot be used.When you move away from the finder during the shooting, prevent light entering with a shield such as an eyepiece cap.Because the optical system has different characteristics from ordinary interchangeable lenses, when the FSA-L2 and a Fieldscope are used for shooting with a digital SLR camera, exposure may vary with the camera model. Use exposure compensation if necessary.Exposure compensation may be necessary when used at wide setting.Aperture and focal length vary depending on the actual zoom setting, however, the aperture and focal length of the camera itself are indicated at 13 and 800. | |
| Focus: Manual focus using the focusing ring on the Fieldscope body. | |
| "Autofocus" and "Manual focus with electronic rangefinder" function cannot be used.When a lens is used at a telephoto setting, the viewfinder image becomes darker because of the changes in F-number. Please take into consideration that in this situation it may be difficult to focus. | |
| Zoom: | Operate using the zoom ring. Rotate clockwise for telephoto side setting, and rotate counterclockwise for wide setting. |
| Shutter release: To reduce vibration caused by shutter release, please use the following mode/items:Exposure delay mode, remote cord, self-timer, remote control, Modulite Remote Control Set ML-3, etc. | |
| When using a tripod, please use a sturdy and stable model. | |
| Fixing to a tripod: It is important to take the anterior/posterior balance into consideration when attaching a tripod. | |
| Keep a well-balanced position by using the three tripod screw sockets located on the EDG Fieldscope body. | |

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), if the GT contains lines used for stylistic emphasis or as background elements (like ruled paper), the OCR result must ignore them. The provided OCR content is "____", which consists of four underscores. This is incorrect because underscores are not equivalent to a solid line and are not permitted under the “Stylistic/Background Lines (Ignore)” rule. Outputting underscores for a stylistic line violates the rule and constitutes an error. Therefore, the OCR result is inconsistent with the Ground Truth.
