Guidelines and manufacturer’s declaration - electromagnetic immunity
The Mobil-O-Graph
®
blood pressure monitor is intended for use in the environment specified below. The pur-
chaser or user of the Mobil-O-Graph
®
blood pressure monitor should ensure that it is used in such an environ-
ment.

Portable and mobile RF communications equipment should

where
p
is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufac-
turer and
d
is the recommended separation distance in
metres (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 “non-ionising radiation” 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 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 theoretical-
ly with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnet-
ic site survey should be considered. If the measured field strength in the location in which the Mobil-O-Graph
®
blood pressure monitor is used exceeds the applicable RF compliance level above, the Mobil-O-Graph
®
blood
pressure monitor should be observed to verify normal operation. If abnormal performance is observed, addition-
al measures may be necessary, such as reorienting or relocating the Mobil-O-Graph
®
blood pressure monitor.
Recommended separation distances between portable and mobile
RF communications equipment and the Mobil-O-Graph
®
blood pressure monitor
The Mobil-O-Graph
®
blood pressure monitor is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Mobil-O-Graph
®
blood pressure mon-
itor can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Mobil-O-Graph
®
blood pressure monitor as rec-
ommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where
p
is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorp-
tion and reflection from structures, objects and people.
