DEVICE CALIBRATION
The caliber interval depends on the use and load and should be between one and two years. Calibration
can be done by Kathrein customer service. For address see next page.
OUTSIDE CLEANING
For outside cleaning a soft cloth, non-linting duster or paint brush is recommended. For strong
contamination spirit or mild soapsuds can be used as well. Never use any dissolvers like nitro-cellulose
combination thinner, acetone, etc., as these may damage the plastic parts and labels.

Since inside cleaning requires opening the device, such activity must be done by authorized personnel
only. The device should be dust-cleaned inside in regular intervals, app. every one to two years, to

in operating rooms. For inside cleaning remove the back wall or the control part. Dust deposits can
be removed using a brush or grease-free compressed air.
