124 Specifications Welch Allyn Propaq Encore Vital Signs Monitor
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment
and the Propaq Encore Monitor
The Propaq Encore monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the monitor can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the monitor 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.
Note 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2 These guidelines might not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
