2.2.5 Extension Frame, F-EXT4
1. If the F-EXT4 contains a fan, check that the fan is running.
2. Check that the modules in the F-EXT4 are recognized, i.e. the required parameter
information is shown on the monitor screen.
Disconnect the Extension Module, E-EXT shortly, then reconnect the module back into the
F-CU8.
Check that the modules in the F-EXT4 are still recognized.

2.2.6 Compact Airway Module, E-CXXXXX
1. Check that the fan is running.
2. If the module contains membrane keys on the front panel, press each of the keys for at
least one second and check that they are identified.
3. Wait until the message ‘Calibrating gas sensor’ disappears from the screen, then enter
the Compact Airway Module General service menu.
Check that the module configuration displayed corresponds with the Compact Airway
Module type being used.
4. Check that the Time-outs, Bad checksums and Bad c-s by mod values are not increasing
faster than by 5 per second.
5. Enter the Gases service menu: Check that the ‘Ambient’ value displayed corresponds with
the current ambient pressure (±20 mmHg).
6. Check that the flow measurement offset, i.e. the sample ‘Zero’ value displayed is within
±10 ml/min.
7. Perform a sampling system leak test.
8. Check the flow rates. Adjust the sampling flow, if necessary.
9. Perform a gas calibration:
NOTE: For maximum accuracy, a warm-up time of 30 minutes is recommended.
NOTE: For correct measurement values, modules need different amounts of oxygen in the
calibration. If you do not use the recommended calibrating gases, the calibration does not
succeed.

Compact Airway Modules with the option
10. Enter the Gases service menu.
Feed calibrating gas (order code 755583) continuously for at least 30 seconds and check
that the ‘ID’ in the service menu shows ‘DES’ and that the value for ‘ID unrel.’ is lower than
75.
