Guidance and Manufacture’s Declaration - Electromagnetic Immunity
The Performance Table is intended for use in the electromagnetic environment specified below. The customer or the user
should assure that it is used in such an environment.

Portable and mobile RF communications equipment should
not be used closer to any part of the Performance Table,
including cables, than the recommended separation
distance calculated by the equation applicable to the
transmitter frequency.

Where P is the transmitter maximum output power rating in
watts (W) according to the transmitter manufacturer and d
is the recommended separation distance in meters (m).

Interference may occur in the surroundings 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.

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 measure filed strength in the location in which the Performance Table is used exceeds the
applicable RF COMPLIANCE LEVEL above, the Performance Table should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
Performance Table.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and the Performance
Table
The Performance Table is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the Performance Table 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 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.
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.
