The VISERA UHD 4K Camera System is a medical imaging device designed for endoscopic procedures, providing high-definition 4K video output. This quick reference guide outlines its basic operation, from initial setup to troubleshooting.

Function Description:

The VISERA UHD 4K Camera System captures and processes high-resolution video during endoscopic examinations. It consists of a camera head, a camera processor, a light source, and a workstation. The system is designed to provide clear, detailed images to assist medical professionals in diagnosis and treatment. Key functions include:

Image Acquisition: The camera head, when attached to a telescope, captures video footage.
Image Processing: The camera processor handles the 4K video data, ensuring high-quality output.
Illumination: The light source provides illumination for the endoscope, crucial for clear visualization within the body cavity.
White Balancing: This feature ensures accurate color representation by adjusting the camera's white balance to the ambient light conditions.
Auto Focus: The camera head includes a one-touch auto-focus switch to achieve sharp images.
High Intensity Mode: Provides brighter illumination for specific endoscopic procedures, especially with larger diameter endoscopes.
Programmable Buttons: The camera head features three programmable buttons for quick access to frequently used functions.

Important Technical Specifications:

While specific numerical specifications are not extensively detailed in this quick reference guide, the following can be inferred:

Resolution: UHD 4K, indicating a very high-definition video output.
Endoscope Compatibility: The system supports various endoscopes, with specific considerations for insertion tube outer diameters (e.g., 4.1 mm or greater for High Intensity Mode, and 2.7 mm for auto-focus limitations).
Light Source Lamp Life: The main examination lamp has a recommended replacement interval, with a meter indicating usage (e.g., not exceeding 500 hours).
Workstation Integration: The system is designed to be part of a workstation, with a master switch controlling its power.
Connectivity: Features standard video and light guide cable connections.

Usage Features:

Switch On: The system is powered on via a workstation master switch, which changes from white to green when active. A secondary power switch on the transformer under the workstation should remain on.
Camera Head Connection: The camera head is inserted into the camera processor, ensuring the UP mark on the connector aligns correctly. It is then attached to the telescope by rotating the endoscope lock ring. Releasing the camera head mount secures the telescope.
Light Source Connection: The light guide cable is connected to the output socket on the light source.
Lamp Standby: The lamp can be placed on standby by pressing and holding the lamp button.
Brightness Mode: The brightness mode button allows selection of "Auto" mode for automatic brightness adjustment.
White Balancing Procedure: After connecting the camera head, telescope, and light guide cable, a white balance must be performed. This involves enclosing the tip of the telescope in a white swab and pressing/holding the white balance button on the processor until "White Balance Complete" appears on the monitor.
Auto Focus Operation: The one-touch auto-focus switch on the camera head adjusts image focus. For optimal results, the telescope lens should be clean, and the telescope held stationary for three seconds after pressing the switch. The auto-focus targets the central 5% area of the monitor. For telescopes with a diameter of 2.7 mm, manual focus using the focus ring may be necessary.
Programmable Buttons: The camera head has three programmable buttons (1, 2, 3) assigned to "Insert action 1," "Insert action 2," and "Insert action 3" respectively.
Information Display: Users can access "Scope information" by pressing the "Info" button on the processor, which displays details such as user preset name, scope model, serial number, and functions assigned to remote switches.

Maintenance Features:

Troubleshooting Guide: The guide provides basic troubleshooting steps for common issues:
- No power: Check if everything is powered on, including the isolation switch on the transformer.
- No image: Verify all components are switched on (including the monitor), ensure the monitor input is set to SDI 1, and check for color bars when the camera head is unplugged. If no colors appear, contact Olympus Service Helpdesk.
- Dark image: Inspect the condition of the telescope and light lead.
- High Intensity Mode doesn't light up: Confirm that a compatible Olympus light lead is being used.
- Main examination lamp doesn't come on: Check the lamp meter on the light source; if it has exceeded 500 hours, replacement is needed.
Lamp Replacement: The light source lamp has a limited lifespan (e.g., 500 hours) and requires replacement when exceeded.
Cleaning: The guide implicitly suggests cleaning the telescope lens for optimal auto-focus performance.

Safety Warnings and Cautions:

Light Source Safety: When turning on the light source, never allow the distal end of an endoscope or a light guide cable to come into contact with the patient and/or other flammable materials (e.g., operating room drapes) to prevent patient injury or fire.
High Intensity Mode Caution: Do not use High Intensity Mode with endoscopes having an insertion tube outer diameter of 4.1 mm or less, as the endoscope can become hot and cause operator burn.
Hot Surfaces: Avoid touching the endoscope's distal end and light guide connector while the examination lamp is lit up, as they can become hot and cause operator burn.
