Welch Allyn Spot Vital Signs 420 Series User Manual

Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and the 420 Series Spot Vital
Signs
The 420 Series Spot Vital Signs is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or user of the 420 Series Spot Vital Signs can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the 420 Series Spot Vital Signs 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 din meters (m) can be estimated
using the equation applicable to the frequency of the transmitter, where Pis 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.
