Floors should consist of wood or
cement or ceramic tiles. If the floor
consists of synthetic materials, relative
humidity must be at least 30%.

Do not use wearable or portable radio
equipment closer to the Tel-O-
Graph
®
BT 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
”
