Electrostatic
discharge (ESD) in
accordance with
IEC 61000-4-2 +/- 8kV
contact discharge
+/- 15kV
air discharge +/- 8kV
contact discharge
+/- 15kV
air discharge Floors should consist of wood or
cement or ceramic tiles. If the floor
consists of synthetic materials, relative
humidity must be at least 30%.
RF radiated
disturbances in
accordance with
IEC 61000-4-3 10 V/m
80 MHz to 2.7 GHz 10 V/m Do not use wearable or portable radio
equipment closer to the Tel-O-
Graph
® GSM or its cables than the
recommended safe distance.
The field strength of stationary radio
wireless transmitters should be lower
than the compliance level at all
frequencies, as shown by an on-site
examination. Interference is possible in
the vicinity of devices bearing the
graphic symbol
“ non-ionising radiation ” .
