SERVICE
DEVICE CALIBRATION
Device maintenance is essentially limited to cleaning the exterior.
The calibration interval is dependent on operational demands made on it and should be carried out every 1
to 2 years. The calibration can be carried out by ESC Kathrein customer service, see below.
EXTERIOR CLEANING
Clean the exterior of the device using a soft cloth, fl uff-free duster or a brush. In case of heavier soiling it is
also possible to use alcohol or a mild soap solution. Under no circumstances is it allowed to use solvents
such as thinners, acetone, etc., as otherwise plastic parts and markings may be damaged.
INTERIOR CLEANING
As it is necessary to open the device to clean the interior, this work is only allowed to be undertaken by aut-
horised service personnel! The device should be freed of dust deposits inside the device every 1 to 2 years
to ensure correct ventilation. The cleaning interval is based on the length of time the device is operated each
day and the amount of dust in the premises. It is necessary to remove the back panel or the control panel for
cleaning. Dust deposits can be removed using a brush or grease-free compressed air.
Caution!
