Table 4: Guidance and Manufacturer’s Declaration: Electromagnetic Immunity
The device is intended for use in the electromagnetic environment specified below. The
customer or the user of the device should assure that it is used in such an environment.

Guidance
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.

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 deter-mined by an
electromagnetic site survey,
should be less than the
compliance level in each
frequency range.
Interference may occur in the
vicinity of equipment marked with
the following symbol:
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 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 re-orienting or relocating the device.
B
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
