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 determined 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 symbol:

At 80 MHz and 8 00 MHz, the higher frequency range applies.

These guidelines may not apply in all situations. Electromagnetic propagation is af-

fected by absorption and reﬂection from structures, objects and people.

2. 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 Coronis 3MP LED Display is used exceeds the applicable RF compliance level above, the Coronis 3MP LED

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 Coronis 3MP LED Display.

3. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than3V/m.
