Recommended separation distance between portable and mobile RF communications equipment and the QardioBase 2 (Model No.: B200)
The QardioBase 2 (Model No.: B200) is intended for use in an electromagnetic environment (for home healthcare) in which radiated RF disturbances are
controlled. The customer or the user of the B200 can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the B200 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 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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects
and people.
