ELECTROMAGNETIC COMPATIBILITY (EMC)
EN
Recommended separation distances between portable and mobile RF communications equipment and the
Cryo Cuff IC is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of Cryo Cuff IC can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and Cryo Cuff IC as recommended below, according to the maximum output power of the communications

For transmitters rated at a maximum output power not listed above, the recommended separation distance d
in meters (m) 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 80 MHz and 800 MHz, the separation distance for 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.
