c) 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 Model XYC100 is to used exceeds the applicable
RF compliance level above, the Model XYC100 should be observed to verify normal operation. If the abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the Model XYC100.
d) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Immunity Requirements
Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The Model XYC100 is intended for use in the electromagnetic environment specified below. The customer or the user
of the Model XYC100 should assure that it is used in such an environment.

equipment should be used no closer to any part
of the Model XYC100, including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended Separation Distance
d = 1.17 x sqrt(P)
d = 1.20 x sqrt(P)
d = 1.17 x sqrt(P), 80MHz to 800MHz
d = 2.33 x sqrt(P), 800MHz to 2.5GHz
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).

should be less than the compliance level in each
frequency range.
d
Interference may occur in the vicinity of
equipment 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) The ISM (industrial, scientific and medical) bands between 150 kHz 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.
b) The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz
to 2.5 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 has been
incorporated into the formula used in calculating the recommended separation distance for transmitters in these frequency
ranges.
