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 the device is used exceeds the applicable
RF compliance level above, the 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 device.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distance
BIOS Diagnostics
TM
ambulatory blood pressure monitor is intended to be used in electromagnetic environment with
controlled RF disturbances. The purchaser or user of the devices may help to reduce electromagnetic disturbances by
defining the separation distance between the transportable or mobile RF telecommunication equipment (transmitters)
and the device, depending on the highest output power of the telecommunication equipment.
Separation distance in function of the frequency of the transmitter (m)
The highest output power of the
transmitter (W)
150KHz-80MHz
d=(3,5/V1)√P
80MHz-800MHz
d=(3,5/E1)√P
800MHz-2,5GHz
d=(7/E1)√P
0,01 Not applicable 0,12 0,23
0,1 Not applicable 0,38 0,73
1 Not applicable 1,2 2,3
10 Not applicable 3,8 7,3
100 Not applicable 12 23
If this table does not contain the highest output power of the transmitter, the d separation distance [m] can be
calculated by the formula, depending on the frequency of the transmitter, where P is the rated highest output power
of the transmitter [W].
Note: in case of frequency 80MHz or 800 MHz, the formula for the higher range is applicable.
Note: These are guidelines. Actual conditions may vary.
