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 from structures, objects, and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land 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 electromagnetic site
survey should be considered. If the measured field strength in the location in which
BC1 ECG Monitor is used exceeds the applicable RF compliance level above,
BC1 ECG Monitor should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the BC1 ECG Monitor.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

The BC1 ECG monitor is intended for use in the electromagnetic environment
specified below. The customer or the user of the BC1 ECG monitor should assure
that it is used in such an environment.
Portable and mobile RF communications
equipment should be used no closer to any part
of BC1 ECG monitor, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
D =1.2√P
D =1.2√P 80 MHz to 800 MHz
D =2.3√P 800 MHz to 2.5 GHz
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 fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range.
Interference may occur in the
vicinity of equipment marked
with the right side symbol:
