Recommended separation distances between portable and mobile RF
communications equipment and The equipment or system-
for EQUIPMENT and SYSTEM that are not LIFE-SUPPORTING
Vital Signs Monitor is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the equipment or system can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the equipment or system 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.
