Environment—Guidance
This device is intended for use in the electromagnetic environment specified below.
The user of this device should ensure that it is used in such an environment.
Portable and mobile RF communications equipment should be used no closer to any part of
the device, including cables, than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended Separation Distance
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to
80 MHz
3 V
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to
2.5 GHz
3 V/m
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 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 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 device is used exceeds
the applicable RF compliance level above, the device should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the device.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3]V/m.
NOTES:
• At 80 MHz and 800 MHz, the higher frequency range applies.
• These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.
