3. セットアップとインストール

3.1 ライフルスコープの取り付け

1. 銃が装填されていないことと、安全な方向に向けられていることを確認してください。
2. Attach the provided mounting rings to your 21mm Picatinny/Weaver rail. Position them appropriately for optimal eye relief.
3. Place the riflescope into the lower halves of the rings.
4. Install the upper halves of the rings and tighten the screws evenly, ensuring the riflescope is level and the reticle is plumb. Do not overtighten.
5. Adjust the riflescope forward or backward in the rings to achieve the correct eye relief for your shooting position.

3.2 視度調整

The diopter adjustment allows you to focus the reticle for your individual eyesight, ensuring a sharp reticle image.

1. Point the riflescope at a plain, bright background (e.g., a clear sky or a blank wall).
2. Look through the eyepiece and quickly glance away. Then, look back through the eyepiece.
3. Adjust the diopter ring (located on the eyepiece) until the reticle appears perfectly sharp and clear the instant you look through the scope.
4. Once set, avoid further adjustment unless your eyesight changes or another user adjusts it.

3.3 Battery Installation (for Illuminated Reticle)

The illuminated reticle requires a CR2032 battery.

1. Locate the illumination control knob, typically on the left side of the riflescope.
2. バッテリーキャップを緩めます。
3. Insert a fresh CR2032 battery with the positive (+) side facing outwards.
4. バッテリーキャップをしっかりと締め直してください。

4. Operating the Riflescope

4.1 倍率調整

The riflescope features a 5-25x magnification range. Rotate the magnification ring (located near the eyepiece) to adjust the power. The numbers on the ring indicate the current magnification setting.

4.2 視差調整

Parallax is the apparent movement of the reticle in relation to the target when the shooter's eye moves off-center. The parallax adjustment knob (typically on the left side, opposite the windage turret) allows you to eliminate parallax error at various distances.

• Rotate the parallax adjustment knob to match the approximate distance to your target.
• To fine-tune, look through the scope and move your head slightly up and down or side to side. If the reticle appears to shift relative to the target, adjust the parallax knob until the reticle remains stationary.
• The parallax adjustment range is from 10 yards (9.144 meters) to infinity.

4.3 Windage and Elevation Adjustment

The windage (horizontal) and elevation (vertical) turrets are used to adjust the point of impact of your shots. Each click of the turret moves the point of impact by a specific amount.

• Click Value: Each click adjusts the point of impact by 1/4 MOA (Minute of Angle).
• 標高調整: The elevation turret (top) provides up to 80 MOA of vertical adjustment. It features a Zero Stop function, allowing you to return to your zero setting quickly and reliably.
• 風偏調整: The windage turret (right side) provides up to 60 MOA of horizontal adjustment.
• To adjust, lift the turret cap (if present) or rotate the exposed turret. Turn the turret in the direction indicated to move the point of impact.

4.4 照明付きレチクル

The reticle can be illuminated in red with 6 adjustable brightness levels. Rotate the illumination control knob (often integrated with the parallax knob) to turn the illumination on/off and select the desired brightness level. Turn it off when not in use to conserve battery life.

4.5 First Focal Plane (FFP) Reticle

This riflescope features a First Focal Plane (FFP) reticle. In an FFP scope, the reticle physically changes size as you adjust the magnification. This means that the subtensions (the spacing between reticle marks) remain constant relative to the target, regardless of the magnification setting. This is beneficial for range estimation and holdovers at any power setting.

5. メンテナンス

5.1 レンズのクリーニング

To maintain optimal optical performance, keep the lenses clean. Use the provided cleaning cloth or a high-quality lens cleaning kit.

• Gently brush off any loose dust or debris from the lens surfaces.
• Apply a small amount of lens cleaning solution (if using) to the cleaning cloth, not directly to the lens.
• Wipe the lenses in a circular motion, starting from the center and moving outwards.
• Avoid using harsh chemicals, abrasive cloths, or excessive force, as this can damage the lens coatings.

5.2 一般的な手入れと保管

• Always use the protective lens caps when the riflescope is not in use to prevent scratches and dust accumulation.
• ライフルスコープは、直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。
• The riflescope is designed to be shockproof, rainproof, and fogproof, but avoid unnecessary exposure to harsh conditions or impacts.
• Periodically check all mounting screws and rings for tightness.
