Guidance and manufacture’s declaration – electromagnetic immunity
TC200 is intended for use in the electromagnetic environment specified below. The customer or the user of TC200 should assure that
they are used in such an environment.

cables and external antennas) should be used
no closer than 30 cm (12 inches) to any part of

manufacturer).
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 device
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.
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 TC200 is used exceeds the applicable RF compliance level above, TC200 should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating TC200.
b. Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3V/m.
c. The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to
13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz and 80 MHz
are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2
MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0
MHz.
