Environment Guidance
Potable and mobile RF communications equipment should be used no closer to any part of the
Smartsigns
® Liteplus , including cables, than the recommended separation distance calculated
from the equation appropriate for the frequency of the transmitter.

Note: Field strengths from fi xed 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 survey accuracy. To assess the
electromagnetic environment due to
fi xed RF transmitters, an electromagnetic site survey
should be considered. If the measured fi eld strength in the location in which the Smartsigns ®
Liteplus is used exceeds the applicable RF compliance level above, the Smartsigns ® Liteplus
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Smartsigns
® Liteplus.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and re
fl ection from structures, objects, and people.
Interference may occur in the vicinity of equipment marked with the following
