2.1. Feste objektivet

1. Carefully remove the protective caps from both ends of the ELP LU04 lens.
2. Align the lens with the lens mount on your compatible Epson projector. Ensure the alignment marks on the lens and projector match.
3. Gently insert the lens into the projector's lens mount.
4. Rotate the lens clockwise until it clicks securely into place. Do not force the lens if it does not align easily.
5. Once installed, replace any protective covers or panels on the projector as instructed in the projector's manual.

2.2. Innledende justeringer

After installation, power on the projector. You may need to perform initial adjustments for focus and zoom. These adjustments are typically made using the projector's remote control or on-screen menu, or by manually rotating the zoom and focus rings on the lens itself, depending on the projector model and lens features.

3. Betjening av linsen

The ELP LU04 is a zoom lens, allowing you to adjust the image size without moving the projector. It also features focus adjustment to ensure a sharp image.

3.1. Zoomjustering

To adjust the zoom, locate the zoom ring on the lens barrel. Rotate the ring to increase or decrease the projected image size. Rotating the ring in one direction will make the image larger, while rotating it in the opposite direction will make it smaller. Adjust until the image fills your screen or desired area.

3.2. Fokusjustering

After adjusting the zoom, you will need to adjust the focus. Locate the focus ring on the lens barrel. Rotate this ring until the projected image appears sharp and clear across the entire screen. It is recommended to focus on text or fine details to achieve optimal clarity.

3.3. Lens Shift (Projector Dependent)

Some compatible projectors may offer lens shift functionality, which allows you to move the projected image vertically or horizontally without tilting or moving the projector. This feature is controlled by the projector and not directly by the lens. Refer to your projector's manual for details on using lens shift with the ELP LU04.

4. Vedlikehold og stell

Proper maintenance ensures the longevity and optimal performance of your ELP LU04 lens. Always handle the lens with care to avoid damage to the optical elements.

4.1. Rengjøring av linsen

• Støv: Use a soft, lint-free cloth or a lens brush to gently remove dust from the lens surface. A can of compressed air (held upright to prevent propellant discharge) can also be used for stubborn dust particles.
• Flekker/fingeravtrykk: For smudges or fingerprints, use a specialized lens cleaning solution applied to a clean microfiber cloth. Gently wipe the lens surface in a circular motion from the center outwards. Never spray cleaning solution directly onto the lens.
• Unngå: Do not use abrasive cloths, paper towels, or harsh chemical cleaners (e.g., ammonia-based cleaners) as these can scratch or damage the lens coating.

4.2. Oppbevaring

  • Confirm the projector's throw distance is appropriate for a short-throw lens.
• Dust spots or smudges on the projected image:
  • Clean the lens surfaces as described in the Maintenance section.
  • Check the projector's internal optics for dust (refer to projector manual or contact service).
