Separation Distance/ Portable & Mobile RF Communications Equipment
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and the MODEL
The Model XYC100 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Model XYC100 can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the Model XYC100 as recommended
below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance 'd' in meters can be
estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of
the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE 2: 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.
NOTE 3: An additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended
separation distance for transmitters in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80
MHz to 2.5 GHz to decrease the likelihood that mobile/portable communications equipment could cause interference if it is
inadvertently brought into patient areas.
NOTE 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.

Electromagnetic Environment - Guidance
The Model XYC100 uses RF energy only for its
internal function. Therefore, its RF emissions are
very low and are not likely to cause any interference
in nearby electronic equipment.
The Model XYC100 is suitable for use in all
establishments, including domestic establishments
and those directly connected to the public low-
voltage power supply network that supplies buildings
used for domestic purposes.
