6. You should ensure that the pressure regulator is chemically and physically compatible with the intended gas cylinder before installation. The
regulator must be properly connected. Note the pressure gauge for the regulator. The physical condition of the regulator, threads and fittings
should also be examined prior to installation. Any dust or dirt on the regulator or cylinder valve should be removed with a clean cloth. The
regulator should not be installed on a cylinder valve if grease or oil is present.
7. The cylinder and pressure regulator must be closed before disconnecting the cylinder from the device.
8. Batteries must be removed from the device when it is not used for a long time.
9. Internal backup battery can be replaced by trained authorized personnel only. The user can only replace the external battery as described in the
dedicated section. Risk of excessive temperatures, fire or explosion.
10. Residue and other contaminants in the breathing circuit pose a safety risk to the patient during testing procedures. Aspiration of contaminants
can be potentially life-threatening. If the recommended disposable anti-bacterial filters are not used, you must disinfect each part coming into
contact with the patient and patient’s breath prior to each test.
11. The cleaning procedures and inspections in the System Maintenance section should be performed prior to each test.
12. This device should not be used in the presence of flammable anaesthetics. This is not an AP or APG device (according to the EN 60 601-1
definitions).
13. The device should not come near any heat or flame sources, flammable or inflammable liquids or gases and explosive properties.
14. The device should not be used in conjunction with any other medical device unless that device is recommended by the manufacturer.
15. The device should be used with a computer with electromagnetic compatibility, CE marking and low radiation emission displays.
16. The PC connected to the device must be compliant with EN 60601-1 by means of an isolation transformer.
17. Precautions regarding EMC should be taken prior to installation and can be noted in the section EMC.
18. Portable and mobile RF communication equipment may interfere with the performance of the device.
19. Only the cable and accessories supplied with the equipment should be used with the device. The use of accessories and/or cables other than
