d = recommended separation distance in meters (m) Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey1, should be less than the compliance level in each frequency range2. Interference may occur in the vicinity of devices with the following symbol:

REMARKS: At 80 MHz and 800 MHz the higher frequency range applies. These guidelines may not apply in all situations. The propagation of elec­ tromagnetic waves is affected by absorption and reflexion from buildings, objects and people. 1 = The field strength of stationary transmitters (e.g. base station for radio phone, earth to earth radio stations,, amateur radio stations, radio and television transmitters) cannot be exactly predicted in theory. To assess the EMC environment due to fixed transmitters an electromagnetic site survey should be conducted. If the measured field strength in the location in which the product is used exceeds the applicable compliance level above, the product should be observed to verify normal operation. If abnormal performance is observed, additional measures may be required, such as reorienting or relocating the product. 2 = Over the frequency range between 150 kHz and 80 MHz the field strength should be below 3 V/m.

Recommended separation distances between portable and mobile HF telecommunication devices and devices which are not life-supporting The product is intended for use in an electromagnetic environment where HF disturbances are controlled. The user can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile HF telecommunica­ tions equipment and the product.

Setup WARNING! The device is not protected against explosions. Explosion hazard. Do not operate this device in areas where there is a danger of explosion. WARNING! Danger if a power supply without protective earth is used. Danger of electric shock! Connect the device only to a power supply with protective earth connec­ tor.

.

NOTE! The line/mains voltage and the voltage indicated on the identification plate must be the same. Connect the device only via the supplied power cable or a power cable with the same specifications. CAUTION! Danger of faults and malfunctions. To guarantee the safety of the user, patient and others, use only acces­ sories and spare parts as specified by the manufacturer of this product. Other accessories or spare parts can cause the emission of increased electromagnetic radiation or reduced immunity against interference.

.

IMPORTANT! Medical electrical equipment is subject to special precautions with regard to electromagnetic compatibility (EMC). Make sure you follow the notes on EMC for installation and operation. Medical electrical devices can be influenced by mobile HF communication devices. Do not arrange the devices side by side and do not stack the devices. If it is necessary to stack the devices or place them next to each other and HF interference is observed, make sure that the devices are ope­ rated as specified in the intended use. CAUTION! The device may fail due to overheating. In the case of insufficient air supply, a warning is issued. There is no automatic over-temperature cutout. Units with a cooling device [e.g. fan] require a minimum distance of 15 cm from the wall and unobstructed vent slots. Do not cover any openings required for cooling. To prevent a possible accumulation of heat in the closed system cart, place the devices accordingly and/or provide vent slots.

.

3.1

Preparation

.

IMPORTANT! Never direct the camera head at the sun or bright light sources in the vi­ cinity. High-energy radiation in the visible and ultrviolet wavelength ranges can damage the CCD chip surface. This may result in color dis­ tortions and image noise. When the camera head is not used, the protection cap must be installed.

.

NOTE! Remove the protection foil from the touchscreen before the initial setup. Z Connect any additional devices such as a monitor or light projector in accordance with the wiring schematic in section 1. Z Switch on the ENDOCAM Logic HD Controller. Z The monitor displays a color bar test chart. Z Prepare a compatible camera head or endoscope for connection (fol­ low the relevant instruction manual).

A

Z Connect the camera head to the camera controller. ' Hold the camera controller with one hand and plug in the camera plug as far as it will go with the two arrows facing upward (A). ' With the camera head completely connected, the two arrows must no longer be visible (B). ' Do not press the buttons on the camera head when connecting the camera plug as this could cause a function failure of the buttons (wrong initialization by the camera controller). Z Disconnecting the camera head from the camera controller. ' Hold the camera controller with one hand and pull out the camera plug axially.

Color bar test chart The color bar test chart of the camera is used for checking the correct cable connections as well as the color saturation and hue of the monitor. Via the color bar test signal the playback of video and S-Video signals can be adjusted to optimum color rendition. Z Pulling the camera plug automatically switches from the camera image to the color bar test chart.

3.6

Adjusting LCD monitors Changing the settings for brightness, contrast, color saturation, chroma etc. has an influence on the color rendition of LCD monitors. For optimum image results in combination with a Richard Wolf ENDOCAM, we therefore recommend using exclusively LCD monitors offered by Richard Wolf. As a rule, these LCD monitors have been preset and balanced before delivery.

Checks .

4.1

IMPORTANT! Run through the checks before and after each use. Do not use the products if they are damaged or incomplete or have loose parts. Return damaged products together with any loose parts for repair. Do not attempt to do any repairs yourself.

Visual check Z Check the device, the instruments and the accessories for damage, loose or missing parts, hygiene and completeness. Z Check all connection cables for damage. Z Any inscriptions, lettering or labeling necessary for the safe intended use must be legible. ' Missing inscriptions, lettering or labeling leading to wrong handling or reprocessing must be reinstated.

4.2

Function check

.

IMPORTANT! Before you perform the function checks, make sure that the devices are in perfect technical condition and are set up correctly. This must also be guaranteed within the scope of the visual check. Z Connect the camera head to the camera controller and the endoscope to the objective lens. Z Check the connectors for secure connections. Z Switch on the camera controller. ' The LED on the power switch lights up. ' After a successful self test the device is ready for operation. Z Switch on all other devices. Z Connect the light cable to the endoscope and switch on the light source. ' Direct the endoscope at an object and check image rendering on the monitor, ensure sufficient image brightness.

CAUTION! Danger of glare. Do not look into the open end when the light cable or endoscope is con­ nected. Z Vary the distance between the endoscope and the object; adhere to the typical working distances for the endoscope in question. ' Through a wide range, the brightness of the monitor image is kept constant by the automatic brightness control.
