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 con-
sidered. 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.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and

Electromagnetic environment Guidelines
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 recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as deter-
mined by an electromagnetic site surveya
be less than the compliance level in each frequency
range. b
