Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The IS-5500is intended for use in the electromagnetic environment specified below. The customer or the user
of the IS-5500 should assure that it is used in such an environment.
Electromagnetic Environment Guidance
RF
IEC 61000-
150 kHz to 80
MHz
Portable and mobile RF communications equipment should
be used no closer to any part of the “Product Name”,
including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
d =
,
150 KHz to 80 MHz
d =
,
80 MHz to 800 MHz
d =
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:
RF
IEC 61000-
4-3
80 MHz to
2,5 GHz
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.
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 IS-5500is used exceeds
the applicable RF compliance level above, the IS-5500should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
“Product Name”.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
