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, and electromagnetic site survey should be considered. If the measured

ﬁeld strength in the location in which the display is used exceeds the applicable RF compliance

level above, the display should be observed to verify normal operation. If abnormal performance

is observed, additional measures may be necessary, such as re-orienting or relocating the Display.

Over the frequency range 150 kHz to 80 MHz, ﬁeld strengths should be less than 3 V/m.

Recommended Separation Distances for the Display

The Display is intended for use in the electromagnetic environment in which radiated disturbances

are controlled. The customer or user of the Display can help prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile RF Communications Equipment and

the Display 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 in meters (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 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.
