Hartmann Veroval Instructions For Use Manual page 97

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) tele-
a
phones 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 Veroval
upper arm blood pressure monitor is used exceeds the applicable RF compliance level above, the
Veroval upper arm blood pressure monitor should be observed to verify normal operation. If
®
abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the Veroval
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Where P is the maxi-
mum output power of
the transmitter in watts
(W) according to the
transmitter manufac-
turer and d is the rec-
ommended separation
distance in metres (m).
Field strengths from
fixed RF transmitters, as
determined by an elec-
tromagnetic site survey,
should be less than the
compliance level in each
range. Interference may
occur in the vicinity of
