Maintenance and servicing
The FernTel-W is maintenance-free.
Nevertheless, if the device is de-
ployed in areas with significant
impurities, it should be cleaned from
time to time. The handset, the
handset rest and the terminal box
should be wiped with a damp
cleaning cloth.
Caution! Never use sharp objects
for cleaning. Please avoid cleaning
and scouring agents.
