P is the maximum output power
rating of the transmitter in watts.
d is the recommended separation
distance in meters.
Field strength from fixed RF
transmitters, as determined by an
electromagnetic site survey,
a
should be less than the
compliance level in each
frequency range.
b
Interference may occur in the
vicinity of equipment marked
with the following symbol.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted accurately. If you wish to use the equipment
in the vicinity of fixed RF transmitters and you are uncertain about the electromagnetic environment, please consider obtaining
an electromagnetic site survey. If the measured field strength in the location where the equipment is being used exceeds the
applicable RF compliance level above, it is the user’s responsibility to verify that the equipment is operating normally. If
abnormal performance is observed, additional measures, such as re-orienting or relocating the equipment, may be necessary.
b
Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
TABLE 3: Recommended Separation Distances (IEC 60601-1-2:2007)
This equipment is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
Observing the recommended separation distances between this equipment and other portable and mobile RF
communications equipment (transmitters) can reduce the likelihood of electromagnetic interference.

For transmitters rated at a maximum output power not listed above, the recommendation 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 may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, object and people.
