Portable and mobile RF communications
equipment should be used no closer
to any part of the ZM-521PA/531PA,
including cables, than the recommended
separation distance calculated from 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
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters,

, should be less than the
compliance level in each frequency

.
Interference may occur in the vicinity of
equipment marked with the following
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
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 ZM-521PA/531PA is used exceeds the applicable RF compliance level above, the ZM-521PA/531PA
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the ZM-521PA/531PA.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m for respiration
and 3 V/m for all other functions.
