Note 1: At 80Hz and 800MHz, 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.
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.
Recommended separation distances for portable and mobile RF communication equipment and the device
The device is intended for use in the electromagnetic environment in which radiated RF disturbances are
controlled. The customer or user of the device can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communication equipment (transmitters) and the
device 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 metres (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 higher frequency range applies.

Portable and mobile RF communication
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:
d = 3,5/3 * SQRT (P/W)
d = 3,5/3 * SQRT (P/W) 80 MHz to 800 MHz
d = 7/3 * SQRT (P/W) 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 recom-
mended separation distance in metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
a
surveya
, should be less than the compliance
level in each frequency range.
