The near-field probes including the accessories does not require special maintenance. 
Users need only take care to keep the equipment clean and protect the components 
against mechanical damage.

 

Users are not permitted to modify the probes or its accessories. 

Clean the probe housing using a dry cloth. For heavy dirt, use a damp cloth with a 
mild, non-abrasive household cleanser if necessary. Do not let liquid enter the housing 
of the probes or the adapters. No chemicals may be used for cleaning purposes.
