2 Planned maintenance check list
2.1 Visual inspection/preparation
2.1.1 General
WARNINGWear a grounded antistatic wristband when handling PC boards. 
Electrostatic discharge may damage components on the board. 
Make sure that the monitor is turned off.
Disconnect the mains power cord. If the monitor is connected to the Datex-Ohmeda 
Network, disconnect the Mon-Net cable from  the monitor. Remove any memory cards.
1. Check all the units visually. Check that all parts are intact and that the cables and screws  are connected and tightened properly.
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.
3. Check that the fuses are of the correct rating.
4. Check the ventilation holes of the mo nitor and clean of dust if necessary.
5. Check the battery status from  Battery setup menu: If “failed”, renew the battery. If 
“condition”, perform the condition cycle. 
NOTE: Batteries are recommended to be conditioned every six months.

2.1.2 Extension module, N-F(C)(REC)
MiniC unit
1. Remove the module cover. 
2. Check that all cables and tubes are connected properly and that there are no loose  objects inside the module.
3. Install the PM Kit: −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. Check that the tubing inside the module is not contaminated. Any contamination inside  the tubing may indicate that the valves or sensors are contaminated, too.
This can increase the risk of faulty operation in  the valves or sensors. It is not possible to 
clean valves or gas sensors in the field. Ther efore, if you notice any contamination in the 
module tubing, send the module to GE Healthcare for factory service.
5. Reattach the module cover and connect the module to the monitor frame.
