Safety

•

Keep the user's manuals where they are easily accessible at all times for the persons operating the instrument.

•

Please do not pull on the cables.

Warning! Do not use the stored video sequences, video clips (cut sequences) and single images for diagnostic purposes, as the video cameras and the monitor have not been calibrated. The visualized images may therefore include deviations in scale, color and shape. This applies in particular if the sequences, clips or images are viewed on a monitor outside the OR, as the transmission to a different monitor may lead to changes in the display. Safe working order •

This instrument is a high-grade technological product. To ensure optimum performance and safe working order of the instrument, its safety must be checked once every 12 months. We recommend having this check performed by our service representative as part of regular maintenance work. If a failure occurs which you cannot correct using the trouble-shooting table, attach a sign to the instrument stating it is out of order and contact our service representative.

Description

System overview Intended use The video camera system has been developed specifically as a documentation system for Carl Zeiss surgical microscopes. State-of-the-art digital electronics provide a brilliant video image and make the objects displayed on the color monitor appear in natural colors. A compact camera control unit (CCU) ensures easy operation of the video camera. There are many different ways of combining the system components into a video camera system. This creates a 3-chip CCD video camera for mono or stereo operation tailored to the field of application involved and to customer requirements. The following illustration shows the combination possibilities of the modules. Note: – For stereo operation, you need two mono cameras whose video output ports are synchronized using a Genlock function. –

G-30-1547-en

If the camera heads and CCUs are interchanged, we recommend performing a white balance and a black balance procedure on reconnection in order to ensure optimum image rendition.

Description

Description of modules Camera block The camera block contains an optical system which project the image generated by the surgical microscope onto the integrated, compact CCD video camera(s). Depending on the application and customer requirements involved, the camera block is equipped with different video camera configurations: –

one 3-chip compact camera for mono applications,

–

two 3-chip compact cameras for stereo applications.

The camera block can be installed in a video objective lens. A centering piece ensures correct optical alignment. Note: It is possible to insert the camera block rotated through 180° (cable support (1) pointing downward) in a video objective lens. In this case, the video image transmitted will be upside down. 1

Powering the CCU up and down (standby mode) 1

Power switch Power switch (1) on the back of the unit is used to completely switch off the device. This switch separates the device from line power. To activate the device, you must press "on" key (2) in addition to the power switch. After the supply voltage has been switched on, all functions of the video camera are available after no more than 15 seconds, and the image received by the camera head is output via all video output ports. After power-on, the connected monitor displays color bars for about 5 seconds (or continuously if the camera head has been disconnected from the CCU or if the camera is defective). All key functions are disabled during this display.

on key The "on" key is used to switch the device from the standard mode to the standby mode and back again. This key is not the power switch. In the standby mode, the device does not respond to any key except the "on" key. The "on“ indicator light (LED) is lit in the standard mode; it is off in the standby mode. Power consumption in the standby mode is very low. There is no need, therefore, to switch off the device at its power switch.
