Instructions for Use for KardiaMobile Card (AC-021)
Recommended separation distances between portable and mobile RF communications equipment
and KardiaMobile Card
KardiaMobile Card is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of KardiaMobile Card can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and KardiaMobile Card 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 (m) can be determined 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.
