2 Planned maintenance check list
2.1 Visual inspection/preparation
2.1.1 General
NOTE:  Wear a static control wrist strap when handling PC boards. Electrostatic discharge may 
damage components on the board.
Make sure that the monitor is switched to standby.
Disconnect the mains power cord. If the monitor is connected to the Datex-Ohmeda Network, 
disconnect the Mon-Net cable from the monitor. Disconnect the WLAN antenna card, if the 
Wireless LAN option is installed.
1. Check all the units visually. Check that all parts are intact and that the cables and screws are 
connected and tightened properly.
Especially check the following parts:
−the equipotential tap and all the screws are tightened properly.
−the display unit locking screw is in a locking position.
Check that modules go in smoothly and lock up properly in all module slots.
Insert the WLAN antenna card back into the foremost card slot, if the Wireless LAN option is 
installed.
2. Replace the batteries, if necessary.
The manufacturer recommendations are:  
−Replace the SRAM/Timekeeper battery on the CPU board every 8 years. 
NOTE: The Factory Reset must be performed if the SRAM/Timekeeper battery is replaced.
NOTE: If the monitor is used for frequent short transportation, refresh the batteries every two 
weeks and replace the batteries every six months.
3. Clean or replace the fan filters in the frame unit and display unit.
4. Check that the fuses are of the correct rating.

2.1.2 Compact Airway Module, E-CXXXXX/ M-CXXXXX
1. Detach the module box.
Check that all cables and tubes are connected properly and that there are no loose objects 
inside the module.
NOTE: The tubes connected to the Oxygen board pressure transducers should not be pressed 
too deep.
NOTE: Make sure that the tubes are not in contact with the sampling pump or the O
2 sensor, or 
its springs.
2. Install the PM Kit:
−Replace the special tubes (Nafion™).
−Replace the Ref. filter assembly.
−Replace the filters in the pneumatic unit (1 or 2 pcs).

                                          Document no. M1031518-02
−Check the D-fend O-rings and replace them, if necessary.
−Replace the D-fend and sampling line.
−Clean or replace the fan filter.
NOTE: Use only approved sampling lines to ensure proper functioning.
Use a 2 m/7 ft. sampling line with Compact Airway Modules E-/ M-COVX and E-/ M-CAiOVX.
3. The manufacturer recommendation is to replace the CO
2 absorber every 4 years. Replace the 
absorber, if necessary.
Note: All Compact Airway Modules do not contain a CO
2 absorber.

Connect the Compact Airway Module to a module slot with a long gas interface cable (the 
grounding plates of the cable should be removed for the procedure).

−Replace the special tube (Nafion™).
−Replace the Zero valve air filter every three years.
−Check the D-fend body connector O-rings and replace them, if necessary.
−Replace the Mini D-fend and the sampling line.
NOTE: Use only approved sampling lines to ensure proper functioning.
4. Connect the module to a module slot with a long gas interface cable (the grounding plates of the 
cable should be removed for the procedure).

2.1.4 Tonometry Module, E-TONO/ M-TONO
1. Detach the module box.
Check that all cables and tubes are connected properly and that there are no loose objects 
inside the module.

−Clean the thermal printhead and the small glass window in front of the static brush with a 
cotton swab dipped in isopropyl alcohol, if necessary.
NOTE: Avoid contact with the rubber paper roller. Be careful to limit the application of alcohol to 
the thermal printhead and the window.
−Reinstall the paper roll.

2.1.6 Modules with NIBP measurement
1. Check the NIBP pump filter. Replace the filter, if necessary.

shortly, normal start-up sound is heard from the loudspeaker and the monitoring screen 
appears.
No error messages should appear on the screen.
3. Configure the screen for the parameters that are connected.
Check that all the connected modules are recognized, i.e. the required parameter information is 
shown on the screen.
If installed, the recorder should record two lines of start-up information.
Preset the measurement settings for those parameters that are connected, for example:
Others - EEG - Montage - EEG Channels - 4
- Montage type - Bip
Others - EEG - EEG Setup - Numeric 1 - MF
- Numeric 2 - Ampl.
