How to install NEC Display L4K-15ZM - Zoom Lens

• Power down the projector and disconnect from power before beginning the lens swap or installation to prevent any electrical or mechanical damage.
• Verify compatibility between the L4K-15ZM and your NEC projector model. Consult the official NEC installation guide or product datasheet to confirm mounting interfaces and compatibility notes for your specific unit.
• Remove any existing lens or cover according to the projector’s service procedures, taking care to avoid dust ingress and to protect the projector’s internal optics during the swap.
• Attach the L4K-15ZM to the projector’s lens mount, aligning the lens with the mounting index and ensuring the collar seats securely. Tighten mounting screws evenly to avoid misalignment.
• Engage the lens locking mechanism if your model provides one, then perform a basic alignment check by powering on the projector and verifying that the image is centered and properly framed at a standard throw distance.
• Perform auto-focus and autofocus-assisted fine-tuning to achieve optimal image sharpness. If your installation requires a manual focus, adjust with care to prevent over-rotation and potential backlash in the focusing mechanism.
• Calibrate keystone correction and geometry as needed to maintain rectangular images across the screen, especially in rooms with angled screens or unusual projection planes.
• Run a quick test with representative content to verify brightness uniformity and color accuracy across the screen. Adjust zoom settings to obtain the desired image size while preserving edge-to-edge clarity.
• Secure any cables, mount points, and protective covers, ensuring that the lens and projector assemblies are stable and free from strain. Document the installation for maintenance records and future lens swaps.
• Store any unused lens components in their protective packaging and follow NEC guidelines for dust protection and periodic maintenance to maximize long-term performance.
