TELRAD Reflex Finder User Manual

1. บทนำ

The TELRAD Reflex Finder is a specialized sighting device designed for precise aiming in stage lighting, concert spotlights, and various terrestrial applications. Unlike its astronomy-focused counterparts, this version features a bright white LED illumination, making the reticle pattern clearly visible even in broad daylight. Its primary function is to assist users in quickly and accurately pointing a spotlight or other device by aligning the projected reticle with the target.

2. สินค้าหมดview และส่วนประกอบ

The TELRAD Reflex Finder consists of several key components designed for ease of use and robust performance.

• หน่วยหลัก: Houses the optics, LED illuminator, and battery compartment.
• ฐานยึด: A separate base that attaches to your device, allowing the main unit to be easily removed and reattached.
• Reticle Pattern: Projects three concentric rings (4°, 2°, and 0.5° diameters) onto the viewing window for aiming.
• การควบคุมความสว่าง: A knob or switch to adjust the intensity of the white LED illumination.
• สกรูปรับ: For fine-tuning the alignment of the reticle.

3.1. Attaching the Mounting Base

1. Identify a suitable, clear space on your spotlight or device for mounting. Ensure the surface is clean and dry.
2. The mounting base comes with double-sided adhesive tape. Peel off the protective backing from the adhesive on the base.
3. Carefully align the mounting base on the desired surface and press firmly to ensure a secure attachment. Alternatively, Gaffer tape (not included) can be used for temporary or more flexible mounting.
4. Allow the adhesive to set for the recommended time (refer to adhesive instructions if available) before attaching the main unit.

3.2. การติดตั้งแบตเตอรี่

The TELRAD Reflex Finder requires 4 AA batteries (not included).

1. Locate the battery compartment cover, typically on the underside or side of the main unit.
2. Slide or open the cover according to the markings.
3. ใส่แบตเตอรี่ AA 4 ก้อน โดยตรวจสอบให้แน่ใจว่าขั้ว (+/-) ถูกต้องตามที่ระบุภายในช่อง
4. ปิดฝาช่องใส่แบตเตอรี่ให้แน่น

3.3. Attaching the Main Unit to the Base

Once the base is securely mounted and batteries are installed:

1. Slide the main unit onto the mounting base until it clicks securely into place.
2. Ensure it is firmly seated to prevent movement during operation.

4. คู่มือการใช้งาน

4.1. การเปิดเครื่องและการปรับความสว่าง

Locate the brightness control knob on the side of the TELRAD unit. Rotate the knob to turn the unit on and adjust the intensity of the white LED reticle. Adjust the brightness to a comfortable level that allows clear visibility of the reticle against your target, especially in varying ambient light conditions.

4.2. Understanding the Reticle Pattern

The TELRAD projects a unique reticle pattern consisting of three concentric rings. These rings have specific angular diameters:

• Outer Ring: 4 degrees in diameter.
• Middle Ring: 2 degrees in diameter.
• วงแหวนด้านใน: 0.5 degrees in diameter.

These rings provide a visual reference for aiming. To point your spotlight or device, look through the TELRAD and move the device until the desired ring (or the center of the pattern) is aligned with your target.

4.3. Aligning the Finder

For precise aiming, the TELRAD Reflex Finder needs to be aligned with the device it is mounted on. This typically involves:

1. Point your spotlight or device at a distant, stationary target.
2. Look through the TELRAD and use the adjustment screws (usually two for horizontal and vertical alignment) to move the reticle pattern until its center aligns with the target.
3. Repeat this process until the reticle remains centered on the target when the spotlight is also accurately aimed.

5. การบำรุงรักษา

5.1. การทำความสะอาด

• Use a soft, lint-free cloth to gently wipe the exterior of the unit.
• สำหรับ viewing window, use a lens cleaning solution and a microfiber cloth specifically designed for optics. Avoid abrasive materials or harsh chemicals.
• ตรวจสอบให้แน่ใจว่าไม่มีความชื้นเข้าไปในส่วนประกอบภายใน

5.2. การเปลี่ยนแบตเตอรี่

Replace batteries when the reticle illumination becomes dim or inconsistent. Refer to Section 3.2 for battery installation instructions.

5.3. การจัดเก็บ

When not in use for extended periods, it is recommended to remove the main unit from its mounting base and store it in a dry, dust-free environment. Remove batteries if storing for very long durations to prevent leakage.

6 การแก้ไขปัญหา

• เส้นเล็งไม่ชัดหรือมองไม่เห็น:
  • ตรวจสอบระดับแบตเตอรี่และเปลี่ยนหากจำเป็น
  • ตรวจสอบให้แน่ใจว่าใส่แบตเตอรี่ในขั้วที่ถูกต้อง
  • Adjust the brightness control knob.
• Reticle is not aligned with target:
  • Re-align the finder using the adjustment screws as described in Section 4.3.
  • Ensure the mounting base is securely attached and not loose.
• เครื่องไม่เปิดเครื่อง:
  • Verify batteries are new and correctly installed.
