Vital Signs Monitor is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or user of the Advisor

Vital Signs Monitor can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Advisor

For transmitters rated at a maximum output power not listed above, the recommended separation distance k
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 animals.
