CE MARKING: The instrument conforms to the European Directives 2004/108/CE and 2006/95/CE with reference to the generic standards:
EN 61000-6-2 (immunity in industrial environment) EN 61000-6-3 (emission in residential environment) EN 61010-1 (safety).
MAINTENANCE: Repairs must be done out only by trained and specialized personnel. Cut power to the device before accessing internal parts.
Do not clean the case with hydrocarbon-based solvents (Petrol, Trichlorethylene, etc.). Use of these solvents can reduce the mechanical
reliability of the device. Use a cloth dampened in ethyl alcohol or water to clean the external plastic parts.
SERVICE: In GEFRAN è disponibile un reparto di assistenza tecnica. The warranty excludes defects caused by any use not conforming to these
instructions.
