Electromagnetic Immunity Guidance
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The P7900 and HR and RR Monitoring System are intended for use in the electromagnetic environment specified
below. The customer or the user should make sure they are used in such an environment.

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 range.
a. 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 can not 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 P7900 is used exceeds the applicable RF compliance level above, the P7900 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the P7900.
Interference may occur in the vicinity of equipment marked
with this symbol.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
