SYSTEM INSPECTION Prior to using your video system, it is essential that all components of the system be inspected for damage which can negatively impact the camera or other equipment performance. This inspection should include all equipment to be used in surgery, including scopes, cables and accessories.

inspected in the same manner, by holding one end up to a good light and inspecting the other end. The fiber area should appear white or clear. If there are damaged fibers, they will appear as black dots or dark gray areas. Replace the scope when 15–20% of the fibers are damaged.

VIDEO CAMERA AND ACCESSORIES • Remove the video camera and accessories from the shipping container. Insure that all boxes and sealed plastic bags inside the shipping container are opened and inspected to insure that all components are accounted for. Refer to accessory package for components. • Inspect all video components for damage during shipment. Contact your Smith & Nephew representative if damage is noticed. Note: Follow the guidelines provided in this section and the Sterilization section of this manual before proceeding with surgery.

ENDOSCOPES Damage to the scopes can impact performance. For more information, please consult endoscope Instructions for Use. The possible causes for scope damage are: • Scratches and/or chips can cause a blurry or out-of-focus image. Examine the distal and proximal lenses for scratches and/or chips. • Dings or dents in the shafts of the endoscope can crush the glass fibers, resulting in less light and/or a distorted image. Examine the shaft of the endoscope to insure integrity. • Residual buildup of sterilization can cause blurry and streaked images on lenses, or can bake onto the lenses and fiber optic cable post causing a yellow filtering effect on the image. Check distal and proximal lenses and the fiber optic post and remove buildup with an alcohol prep or cotton swab dipped in alcohol. Prevent future problems by observing the correct sterilizing procedure outlined in this manual, including cleaning the lens with alcohol and a cotton swab after each soaking. • Damaged fibers cause significant breakdown in quality of operation. Check the scope for fiber damage by aiming the distal end of the scope toward a light and looking at the amount of broken fiber bundles in the fiber optic post (Figure 4). Fiber optic light guides should be

Figure 4. Checking for Damaged Fiber Optics

• Verify that the picture is clear by looking through the scope (direct view only).

FIBER OPTIC CABLES • Cuts, abrasions or tears in the silicone sheath cause a loss of light. Check the sheath for damage. • Aim one end of the cable toward a light and observe the other end, just as you did with the scope (Figure 4). Check for damaged fibers (e.g., black dots or dark gray areas). A combination of broken fibers in the cable and the endoscope will result in loss of light. The combined percentage should not exceed 15–20%. • Perform a visual fiber bundle diameter comparison. For optimal light transmission, the diameter of the fiber bundles in the scope’s fiber optic post should match the fiber cable's diameter.

LIGHT SOURCE Verify that the light source is producing the correct amount of light. Factors that can affect the light output include: • Improper bulb placement • Blown fuses and/or thermocouples • Worn-out or burned-out bulbs Refer to the manufacturer’s Operations Manual if you suspect problems with the light source.

SYSTEM INSPECTION (continued) ELECTRICAL CONNECTIONS

COLOR MONITOR ADJUSTMENT TIPS

Examine the electrical connections: • Electrocautery and other electrical noise-inducing medical equipment can interfere with the performance of the camera and monitors. To prevent interference, plug monitors and camera equipment into an outlet on a wall separate from noise-inducing equipment. • Check that the electrical equipment is properly grounded (i.e., plugs contain a ground prong). The camera must be plugged into a hospital-grade AC outlet. • If the monitor has a Termination switch, it needs to be set to 75 Ω (ohms). If two or more monitors are used, only the last one needs to be ON. • Double check the equipment setup diagrams to insure that the connections are correct.

Below are some tips for adjusting color video monitors: • Connect your monitor in accordance with its instruction manual, setting the Termination switch as explained in this section under Electrical Connections. • Most monitors have a Reset button on the front panel which, when pressed, will restore settings to the factory settings. If this is not the case, continue with the following steps: • Begin with contrast (picture) and brightness controls in the middle or mid-detent position. Adjust brightness slightly so that black is black and white is white. Note: Too little brightness causes loss of detail in blacks; too much brightness makes the black look green; too much contrast makes the colors and picture dark. • Color saturation is adjusted with the chroma (color) adjustment knob or button. Decreasing this setting will reduce the amount of overall color perceived in the image. In the fully decreased position, the image will be black and white. Too much color saturation makes the image unpleasant to look at and the colors appear noisy or smeared. • Adjust the hue (tint or phase) back and forth until a good balance of orange and purple (cyan and magenta) is achieved. Note: If your monitor is equipped with a “Blue Only” adjustment, when the color bars are displayed, press the Blue Only button. Adjust the color and tint controls to achieve a balance between the dark lines and the light lines so that all black lines are evenly balanced, and all white lines are evenly balanced. When balance is achieved, press the Blue Only button again to restore normal operation.

CABLE CONNECTORS Video systems commonly use three types of cables: BNC coaxial cables, S-VHS cables which have a 4-pin mini-Din connector, and Sub “D” connectors. Figure 5 explains how to use these video cable connectors.

INSTALLATION AND OPERATION (continued) INSTALL THE VIDEO ACCESSORIES

TURN THE CAMERA ON

Install the video accessories using the diagrams in the Equipment Setups section as a guideline. Below are some tips regarding video setup: • When connecting video accessories (monitors, VCRs or printers) to the camera, always connect the cables using the video camera outputs to the video inputs of the accessory equipment. • When linking pieces of equipment in a chain, the last piece of equipment should be set in the 75 Ω or the “ON” position. If there is not a 75 Ω or “ON” switch, your equipment is self-terminating and you do not need to perform this step. • When using monitors or printers having RGB/Sync settings, connect the RGB/Sync outputs on the camera directly to the RGB/Sync inputs of the accessory monitor or printer. You should use a BNC style RGB cable because the camera’s RGB/Sync outputs are standard BNC coaxial cable connectors. Use the RGB input with the video printer for best results. • When connecting Super VHS recorders (S-VHS), monitors or printers, connect the 4-pin mini-Din Y/C (S-Video) connectors directly to the Y/C (S-Video) input of the accessory equipment. Note: See the Equipment Setups section for diagrams of multiple accessory setups and configurations.

1. Plug the female end of the power cord into the power receptacle on the CCU rear panel. 2. Verify that the power outlet corresponds to the data on the rear panel label and that the third pin on the plug is properly grounded. 3. Plug the power plug into a hospital-grade AC power outlet. 4. Turn the power switch on the CCU front panel “ON.” The power switch and the COLOR BAR button will illuminate green and color bars will appear on the monitor screen. Note: Color bars will not appear if the camera head is already plugged into the CCU. REMINDER: Use a hospital-grade AC power outlet.

INSTALL THE CHARACTER GENERATOR Connect the character generator cable to the character generator input port on the CCU rear panel by aligning the pins and pushing in firmly. Detailed operating instructions are supplied with the character generator. Note: See the Equipment Setups section for diagrams of multiple accessory setups and configurations.

ADJUST THE MONITOR TO THE COLOR BARS Color bars are used to test and adjust the color on the monitor to the desired contrast, sharpness and color levels. 1. Turn the monitor power “ON.” 2.
