Electromagnetic Immunity Guidance
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The P7500 is intended for use in the electromagnetic environment specified below. The customer or the user
of the P7500 should make sure it is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the P7500, includ-
ing cables, than the recommended separation distance
calculated from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
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 in metres (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey

compliance level in each frequency range

Interference may occur in the vicinity of equipment marked
with this symbol.
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 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 P7500 is used exceeds the applicable RF compliance level above, the P7500 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the P7500.
b. Over the frequency range of 150 kHz to 80 MHz, field strength should be less than 3 V/m.
Note 1: At 80 MHZ and 800 MHz, the higher the 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.
