custo cardio 400 troubleshooting (both device variants)
In the event of an error, the custo cardio 400 suction level display lights up yellow
or red. The cause of a warning is saved in the custo cardio 400 error log file and
can be viewed there.
In order to open the error log file, the custo cardio 400 device must be connected to
the PC via USB. In this case, the device is displayed as custo cardio 400 mass stor-
age. Open the directory of the custo cardio 400 mass storage via Windows Explorer.
The file is called „error.log“ and can be opened with a text editor.
Warning indicator lights up yellow
The system is leaking
The device tries to gain the preset pressure for over five minutes, e.g. 280 mbar
(suction level 6). If this does not succeed, the device switches off and the warning
indicator lights up yellow.
Troubleshooting:
Start the device without a patient (press the On/Off button). If
the device controls extremely often (engine noise), there is a mechanical problem:
one or more sealing rings on the leads are missing / stuck in the housing
the electrodes are not tight (dirt, e.g. from hair)
the device has an internal defect (service case)
If the device is tight without a patient,
check and correct the following points when used on patients:
Selection of the suitable electrode type (small, normal, hair)
Placing the electrodes on a less hairy part of skin / shave patient
Selection of a lower suction level which is more easily achieved.
Note: electrodes adhere less strongly, possibly reduced quality
of the derivations.
The pressure in the system is too high
The system may be clogged, e.g. too much moisture in the leads. Start a cleaning
cycle with the cleaning button (longer blowing out of the leads).
If this error still occurs or if the red light indicator
appears during cleaning, con-
tact your authorised custo med dealer.
Warning indicator lights up red
Defect on the device
