1. Overview
The Steiner P4Xi 1-4x24mm Riflescope is a high-performance optic designed for use on patrol rifles and other law enforcement platforms. It offers a compact design, true 1x magnification at close range, and an illuminated P3TR reticle for versatile use in various lighting conditions. This riflescope is built with durable aluminum material and is engineered for reliability and precision.
2. Setup
Proper setup is crucial for optimal performance of your Steiner P4Xi riflescope. Ensure the scope is securely mounted to your rifle using a compatible ring mount system.
2.1 Mounting
Attach the riflescope to your rifle using a suitable ring mount. Ensure all mounting screws are tightened to the manufacturer's recommended torque specifications to prevent movement during use. The scope is designed for a secure fit on rifle platforms.
2.2 Turret Adjustments
The P4Xi features low-profile covered turrets for windage and elevation adjustments. These turrets are designed to be less likely to snag during movement. To adjust, unscrew the protective caps. The turrets provide a half-click MOA adjustment, allowing for precise zeroing. Once zeroed, it is generally recommended to leave these adjustments set, as this type of optic is typically zeroed once and then used without frequent adjustments.

2.3 Illumination Controls
The illuminated P3TR reticle features 5 day, 4 low light, and 2 night vision (NV) levels. The illumination control knob is located on the side of the scope. Each setting has an 'Off' position in between, which completely disconnects the battery to prevent drain when not in use. Rotate the knob to select your desired brightness level or to turn the illumination off.

3. Operating
3.1 Magnification Adjustment
Adjust the magnification from 1x to 4x by rotating the magnification ring located near the eyepiece. The true 1x magnification is ideal for close-quarters engagements, while higher magnifications provide clarity for longer distances.

3.2 Reticle Illumination
The illuminated P3TR reticle enhances visibility in various lighting conditions. Turn the illumination control knob to activate the reticle and select the appropriate brightness level. Remember to turn the illumination off when not in use to conserve battery life.
4. Maintenance
4.1 Cleaning
To clean the lenses, use a soft, lint-free cloth and a lens cleaning solution specifically designed for optics. Gently wipe the lens surfaces to remove dust and smudges. For the riflescope body, a damp cloth can be used to wipe away dirt. Avoid using abrasive materials or harsh chemicals.
4.2 Water Resistance
The Steiner P4Xi riflescope is water resistant to 33 feet. While it can withstand immersion, it is recommended to dry the scope thoroughly after exposure to water to prevent water spots and ensure longevity.
4.3 Storage
Store the riflescope in a cool, dry place away from direct sunlight and extreme temperatures. Use a protective cover or case to prevent scratches and impacts.
5. Troubleshooting
If you encounter any issues with your Steiner P4Xi riflescope, please refer to the following general advice:
- No Reticle Illumination: Check the battery. Ensure the illumination control knob is not set to an 'Off' position.
- Unclear Image: Adjust the diopter setting on the eyepiece to match your vision. Ensure lenses are clean and free of smudges.
- Zero Shift: Verify that the scope is securely mounted and that all screws are properly torqued.
