TABLE 19-3
GUIDANCE AND DECLARATION - ELECTROMAGNETIC IMMUNITY
The Passport V is intended for use in the electromagnetic environment specified below. The customer or
the user of the Passport V should assure that it is used in such an environment.

ENVIRONMENT - GUIDANCE
Portable and mobile RF communications
equipment should be used no closer to
any part of the
Passport V , including
cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation
distance
Conducted RF
IEC 61000-4-6 3 Vrms
150 kHz to 80 MHz 3 Vrms
d
= 1.2 x
Radiated RF
IEC 61000-4-3 3 V/m
80 MHz to 2.5 GHz 3 V/m d = 1.2 x 80 MHz to 800 MHz
d
= 2.3 x 800 MHz to 2.5 GHz
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,
as determined by an electromagnetic site
survey,
a
should be less than the
compliance level in each frequency
range.
b
Interference may occur in the
vicinity of equipment marked
with the following symbol:
NOTE: At 80 MHz and 800 MHz, the higher frequency range
applies.
NOTE: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
NOTE: The device that intentionally receives RF electromagnetic
energy at the exclusion band (2409.5MHz-2464.5MHz) is
exempt from the wireless performance requirements, but
remains safe.
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 theo-
retically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electro-
magnetic site survey should be considered. If the measured field strength in the location in which the
Passport V is used exceeds the applicable RF compliance level above, the Passport V should be observed to ver-
ify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the Passport V.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
