MAINTENANCE

The device maintenance is basically limited to outside cleaning.

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.

INSIDE CLEANING

Caution!

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 ensure optimum ventilation. Cleaning intervals are based on the daily operating time and the dust volume 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.
