6. Open the four screws holding the metal EMC cover in the Display Unit front cover.
7. Open the two screws covering the video flat cable and ferrite in the LCD Display element.
8. Lift the EMC cover carefully up.
9. Open the four screws holding the LCD element in the Display Unit front cover.
10. Lift the LCD Display element carefully up.
NOTE: Do not use excessive force when fastening the display component to the metal frame.
Fastening the screws too tightly might bend the display module too much and break it. The screws
must also be fastened gradually: first fasten all screws slightly, then more tightly.
NOTE: When reassembling the LCD Display component, be careful that no dirt or finger prints are left
between the LCD element and the protection glass window.
NOTE: If the LCD Display unit is broken, handle it carefully to avoid injury (the LCD Display component
and the backlight lamp(s) are made of glass). Wash your hands if you touched liquid crystal, which
may flow out from a broken LCD Display component.
NOTE: Do not touch, push or rub the exposed display module surface. Keep the surface clean. In case
of accidental mishandling, see the instructions following this chapter.

6. Open the four screws holding the metal EMC cover in the Display Unit front cover.
7. Open the two screws covering the video flat cable and ferrite in the LCD Display element.
8. Lift the EMC cover carefully up.
9. Release the screw holding the backlight tubes in their place.
NOTE: The screw cannot be removed totally, only released.
10. Detach the backlight tube by sliding it to the left and then lift it up.
NOTE: Do not bend the backlight tube.
NOTE: Do not touch the backlight tube with your hands.
Datex-Ohmeda S/5 Compact Anesthesia and Compact Critical Care Monitors 40 Document no. M1031520-02 3.3.13 Changing the LCD backlight, F-CM(C)1 rev.03 and rev.04 Perform the steps 1-8 as in section 3.3.12. Changing the LCD backlights, F-CM(C)(REC)1 rev.01, rev.02. 1. Detach the screw holding the backlight tube set in place. 2. Detach the backlight tube set by pulling it to the left. NOTE: Do not bend the backlight tube. NOTE: Do not touch the backlight tube with your hands. 3.3.14 Handling and storage of LCD Display component Handling of LCD Display component and protective window If the LCD Display component surface becomes dusty, wipe it gently with absorbent cotton, chamois or other soft material. If necessary, breathe onto the display surface and wipe immediately. The display surface may also be cleaned using a small amount of normal hexane. Do not use acetone, toluene or alcohol because they cause chemical damage to the polarizer. 1. Wipe off saliva and water drops as soon as possible. Their prolonged contact with the polarizer cause deformations and color fading. 2. Do not open the component case because internal circuits are sensitive to electrostatic discharges. Taking a spare part LCD Display component or a display shield into use: Peel off the protective film slowly (in more than 10 seconds) from the display or protective window surface. Fast peeling may generate enough static electricity to destroy the LCD Display component. Storaging an LCD Display component as a spare part for a long period 1. Store the display in a dark place. Do not expose it to sunlight or fluorescent light. Keep the temperature between 5 °C and 35 °C at normal humidity. 2. The polarizer surface should not come into contact with any other object. It is recommended that the display unit is stored in the container in which it was originally shipped. 3.3.15 Downloading the software on empty Central Processing Board In case of a faulty Central Processing Board refer first to chapter “To remove the Central Processing Board (CPB) from the Display Unit Back Unit” and then follow the instructions for downloading service software below. NOTE: All user settings will be lost after downloading of a new monitor software. NOTE: During the downloading of the software, the serial number of the monitor is written on the software card. The software can then be downloaded again to the same monitor, but not to any other monitor. 1. Make sure that the monitor is switched to standby. Press and hold the service reset button on the rear panel for at least five seconds or until the service reset indicator LED turns off. 2. Open the cover for card drive slots, if installed. Insert the software card into one of the card drive slots and press the software card firmly in position. 3. Make sure that at least 30 seconds have passed since the service reset, then switch the monitor on.

4. Wait for approximately 80 seconds. After the start-up screen appears, enter the Service View
and make sure that the information regarding the monitor software has been updated.
Memorize the serial number of the new software.
5. Remove the software card.
6. Replace the original device plate for monitor software by the new one supplied with the software
card.
7. Perform Factory Reset. Make sure that the monitor functions normally after the restart.
8. Set the time and date.
9. Set the monitor’s network communication according to the used network software, if necessary.
The communication is set in the monitor’s Network service menu.
Network software S-CNET99 -> DRI Level = 1999
Network software S-CNET01 -> DRI Level = 2001
Network software S-CNET02 -> DRI Level = 2001 or 2002 (WLAN)
Network software L-NET03 -> DRI Level = 2003
