GUIDANCE AND MANUFACTURER'S DECLARATION – ELECTROMAGNETIC IMMUNITY
The BW-X07HD Handheld VitalSigns Monitoring System is intended for use in the electromagnetic environment specified below. The customer or the user of the
BW-X07HD Handheld VitalSigns Monitoring System should assure that it is used in such an electromagnetic environment.

where P is the maximum output power

and d is the recommended separation

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, a should be less than the compli-
ance level in each frequency rangeb
Interference may occur in the vicinity of
equipment marked with the following
symbol:
a. The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to
27,283 MHz; and 40, 66 MHz to 40, 70 MHz. The amateur radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz
to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0
MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz.
b. The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2, 7 GHz are intended to decrease
the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason,
an additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for transmitters in these
frequency ranges.
c. 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 the BW-X07HD Handheld VitalSigns
Monitoring System is used exceeds the applicable RF compliance level above, the BW-X07HD Handheld VitalSigns Monitoring System should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the BW-X07HD
Handheld VitalSigns Monitoring System.
d. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

The BW-X07HD Handheld VitalSigns Monitoring System is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the BW-X07HD Handheld VitalSigns Monitoring System can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the BW-X07HD Handheld VitalSigns
Monitoring System as recommended below, according to the maximum output power of the communications equipment.
