5. INSTALLATION

5.1 SETTING UP THE MSV-2010

1. Place the video camera on a stable surface (cart, counter, stand, etc.).

NOTE - Avoid places where the video camera may be splashed with liquid.

- Absolutely DO NOT use in any environment with explosive or flammable gases.

- DO NOT block the venting grids of the video camera

2. Make sure the power switch is in OFF position.

3. Plug the power cord into the power source using the three (3) prong plug supplied with the unit.

CAUTION - To prevent electric shock, connect power cords of peripheral equipment through

medical isolation transformers.

NOTE - When using medical isolation transformer, be sure to check that the transformer ratings.

Make sure that the power cord is connected to the mains with a three prong plug (In USA use UL2601-1 rated isolation transformers and/or power strips only).

5.2 CONNECTING THE CAMERA HEAD

CAUTION - When removing the camera head from the camera control unit, grasp the connector

area to release the lock mechanism. Pulling the cable could result in damages to the device.

NOTE - Do not connect or disconnect the camera head during operation. It may cause

unrecoverable damage to the camera head.

To connect the camera head to the camera control unit align the red dot on the camera cable connector with the red dot on the CAMERA jack, located on the left side of the camera control unit front panel. Gently push the connector into the jack.

5.3 CONNECTING PERIPHERAL EQUIPMENT

1. The MSV-2010 can be connected to a video monitor via three types of video signals: composite video, Y/C (S-VHS) or RGB.

It is possible to connect up to four appliances including the monitor simultaneously to the different video

outlets of the MSV-2010: VCRs, Image Processing PCs (via frame grabbers) and/or video printers.

2. Depending on the requirements of appliances you will be using, attach the appropriate cables to the rear panel of the camera control unit. For example, if the monitor requires input from a Y/C cable, attach one end of the Y/C cable to the corresponding connector on the rear panel of the camera control unit and the other end to the monitor.

NOTE - For highest quality pictures Y/C or RGB connections are recommended

CAUTION - When used in clinical or residential areas near radio or TV units, this equipment

may be subjected to radio interference. To avoid adverse electromagnetic effects,

DO NOT operate this equipment near RF energy equipment.

Page 18

CAUTION - Use the following connection cables provided with the MSV-2010 and use

keyboard with appropriate CE Marking.

- Use the part # H10-0015 for the RGB Video Cable. Use of other cables could cause poor images or excessive heat resulting in injury or property-damage.

5.4 CONNECTING POWER

1. Connect the AC power cable to the inlet located on the rear panel of the camera control unit.

2. Plug the AC power cable into a wall outlet.

5.5 ASSEMBLING THE OPTO-MECHANICAL ADAPTER

1. Attach the opto-mechanical adapter to the camera head by screwing it into the camera head and tighten slightly. Make sure first to insert the semicircular flange on the opto-mechanical adapter into the semicircular socket on the camera head.

NOTE - While assembling the opto-mechanical adapter and connecting it to the camera head, please make sure that the free-spin lock on the opto-mechanical adapter (refer to Figure 3) is in its locked position.

Page 19

6. OPERATION

6.1 POWERING UP THE MSV-2010

To operate the MSV-2010:

1.Attach the endoscope to the opto-mechanical adapter connected to the camera head (refer to Section 5.5).

2. Attach the light source to the endoscope.

3. Turn on the video camera, monitor and light source. Wait until SETTING list is appeared on the monitor

screen. Do not press any front panel buttons or camera head buttons and any keyboard key until date, time and patient data window are appeared on the monitor screen.

4. Use the focus ring of the opto-mechanical adapter to focus the image. The image positioning on the screen can be adjusted by the free-spin/orientation mechanism (refer to Section 6.2) and the optional centering mechanism (refer to Section 6.3), of the opto-mechanical adapter.

5. Perform the white balance procedure (refer to Section 6.5.1).

6. At any time the image can be adjusted using the touch-buttons on the front panel of the camera control unit

by:

a) Adjusting the brightness level (refer to Section 6.5.3).

b) Using gain control (refer to Section 6.5.2).

NOTE - When the image is being adjusted, text messages appear on the upper line of the message

window of the monitor screen display.

6.2 FREE-SPIN/ORIENTATION MECHANISM

1. While using a flexible endoscope, release the free-spin lock of the opto-mechanical adapter (refer to Figure 3)

and rotate the endoscope until the arrow in the view field points to twelve o’clock. Then return the free-spin lock to its locked position.

2. When using rigid endoscopes, release the free-spin lock of the opto-mechanical adapter, rotate the endoscope

to the required position, then return the free-spin lock to its locked position.

6.3 CENTERING MECHANISM

1. When the opto-mechanical adapter has a centering mechanism (optional), it can be used to center the image

from a flexible endoscope on the screen.

2. The centering mechanism has two adjustment knobs (refer to Figure 3). When the view field of the flexible

endoscope is correctly oriented at twelve o’clock, the knobs are positioned on the top and the right side of the mechanism. Turn these knobs to move the image up or down (right knob) and right or left (top knob) on the monitor.

Page 20
