Field strength from fixed RF
transmitter, 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 marked
with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection form structures, objects and
people.
a
Field strengths from fixed transmitters, such as base station for radio
(cellular/cordless) telephones and mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an
electronic site survey should be considered. If the measured field strength in the
location in which the Vcare
®
device is used exceeds the applicable RF
compliance level above, the Vcare
®
device should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Vcare
®
device.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than

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