4. סעטאַפּ
4.1 מאָנטירן דעם ריפלאָסקאָפּ
The Sentinel-X riflescope comes with 30mm weaver mount rings (or dovetail mount rings on request). Ensure your rifle has a compatible mounting rail. Securely attach the rings to the rail, then place the riflescope into the rings. Adjust the scope's position for proper eye relief before tightening the ring screws. Ensure the reticle is level with the rifle.
4.2 דיאָפּטער אַדזשאַסטמאַנט
The fast-focus eyepiece allows for quick and easy reticle focusing. To adjust the diopter, look through the scope at a plain, bright background (like the sky or a blank wall). Rotate the eyepiece until the reticle appears sharp and clear to your eye. This adjustment compensates for individual eyesight differences and ensures the reticle is in sharp focus.
5. אַפּערייטינג ינסטרוקטיאָנס
5.1 פֿאַרגרעסערונג אַדזשאַסטמענט
Rotate the power ring located near the eyepiece to change the magnification from 10x to 40x. Adjust to your desired magnification level based on target distance and shooting conditions.
5.2 Side Focus (Parallax) Adjustment
The side focus turret, located on the left side of the scope, adjusts for parallax error. Rotate the side focus knob until the target appears sharp and clear, and the reticle does not appear to shift relative to the target when you move your head slightly. The side focus starts at 10 yards and has markings for 25, 50, 100, and infinite.
5.3 ווינטידזש און הייך אַדזשאַסטמאַנץ
The windage (horizontal) and elevation (vertical) turrets are located on the top and right side of the scope, respectively. Each click adjusts the point of impact by 1/8 MOA. To make an adjustment, pull the turret knob up to unlock it, make the desired clicks, and then press the turret knob down to lock it in place. This turret lock feature prevents accidental adjustments.
5.4 Reticle Usage (COM-25M)
The etched glass COM-25M reticle is designed for precision benchrest shooting at 25 meters. When used at 40x power, the 1.5mm center dot perfectly matches a 2mm diameter bull-eye target. Each graduation on the horizontal line of the reticle coincides with all target rings, aiding in precise aiming and holdovers.

6. וישאַלט
6.1 רייניקן די לענסעס
Use the provided cleaning cloth or a soft, lint-free cloth specifically designed for optical lenses. Gently wipe away dust and debris. For stubborn smudges, use a small amount of lens cleaning fluid applied to the cloth, not directly to the lens. Avoid touching the lens surfaces with your fingers.
6.2 אַלגעמיינע זאָרג און סטאָרידזש
- Keep the lens covers on when the riflescope is not in use to protect the lenses from dust and scratches.
- האַלט דעם ריפלסקאָפּ אין אַ קיל, טרוקן אָרט, אַוועק פון דירעקט זונשייַן און עקסטרעמע טעמפּעראַטורן.
- The riflescope is O-ring sealed and nitrogen purged for water and fog proof performance, but avoid prolonged submersion in water.
- The scope is shockproof up to 750g, but handle it with care to prevent damage from severe impacts.
7. טראָובלעשאָאָטינג
7.1 Unclear Image / Blurry Reticle
- Reticle Blurry: Adjust the fast-focus eyepiece (diopter) until the reticle is sharp.
- Target Blurry: Adjust the side focus (parallax) knob until the target is clear and parallax is eliminated.
- General Unclarity: Ensure lenses are clean. Check for fogging (if persistent, contact support).
7.2 Difficulty Zeroing / Inconsistent Point of Impact
- מאַונטינג ישוז: Ensure the riflescope is securely mounted to the rifle. Loose rings or an improperly installed base can cause significant zeroing problems. Check all screws for tightness.
- Turret Lock: Confirm that the windage and elevation turrets are properly locked after making adjustments. If they are not pressed down, they can shift.
- Ammunition Consistency: Inconsistent ammunition can lead to varied points of impact.
- Shooting Technique: Ensure consistent shooting form and proper rifle support.
- Scope Damage: If all other factors are ruled out and the scope consistently fails to hold zero or adjust properly, the scope may be damaged. Contact customer support for assistance.
7.3 Turrets Not Adjusting
- Ensure the turret knob is ארויפגעצויגן to unlock it before attempting to make adjustments. After adjusting, press it down צו שלאָס.
