Guidance and manufacture’s declaration – electromagnetic immunity
The
TR-KID-7
is intended for use in the electromagnetic environment specified below. The customer or the
user of the
TR-KID-7
should assure that it is used in such an environment.
Immunity test

Electromagnetic environment - guidance
Conducted RF
IEC 61000-4-6
3 V

150 kHz to 80 MHz
3 Vrms
Portable and mobile RF communications equipment
should be used no closer to any part of the TR-KID-7,
including 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
transmitter in watts (W) according to the transmitter
manufacturer and
d
is the recommended separation
distance in metres (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:
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2.5 GHz
3 V/m
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 TR-KID-7 is used exceeds
the applicable RF compliance level above, the TR-KID-7 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
TR-KID-7.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
