RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE EQUIPMENT OR SYSTEMS - FOR HANDHELD
ECG MONITOR THAT ARE NOT LIFESUPPORTING
Recommended separation distances between portable and mobile RF communica-
tions equipment and the equipment
The equipment is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the equipment can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the equipment 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 sepa-
ration distance d in metres (m) can be estimated using the equation applicable to the fre-
quency 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 af-
fected by absorption and reflection from structures, objects and people.
