The 7.0 U is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the 7.0 U can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the 7.0 U as recommended below, according to the maximum output power of the
communications equipment.

Electromagnetic environment –
guidance
The 7.0 U uses RF energy only for its
internal function. Therefore, its RF
emissions are very low and are not
likely to cause any interference in
nearby electronic equipment.
The 7.0 U is suitable
for use in all
establishments, including domestic
establishments
Electromagnetic environment
guidance
Floors should be wood, concrete or
ceramic tile. If oors are covered with
synthetic material, the relative
humidity should be at least 30 %.
Power frequency magnetic elds
should be at levels characteristic of a
typical location in a typical
commercial or hospital environment.

Where P is the maximum output
power rating of the transmitter in
watts (W) according to the transmitter
manufacturer and d is the
recommended separation distance in
meters (m).
Field strengths from xed RF
transmitters, as determined by an
electromagnetic site survey, a) should
be less than the compliance level in
each frequency range. B) Interference
may occur in the vicinity of equipment
