Recommended Separation Distances
Separation Distance Notes
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.
Immunity Test IEC 60601 Test Level Compliance Level Electromagnetic Environment Guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the product, including cables, than
the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended Separation Distance
Conducted RF 3 Vrms 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m 3 V/m 80 MHz to 800 MHz
IEC 61000-4-3 80 MHz to 2.5 GHz 800 MHz to 2,5 GHz
Where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer, and d is
the recommended separation distance in meters (m).
Field strengths 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 this 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 theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the product is used exceeds the applicable RF
compliance level above, the product should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the product.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distances Between Portable/Mobile RF Communications Equipment and the Product
This product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of this product can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the product as recommended below,
according to the maximum output power of the communications equipment.
Rated Maximum Output

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.
