The electromagnetic intensity of fixed transmitters, such as wireless devices (cyber/cordless),
telephone station, on-shore movable radio transmission, amateur radio transmission, AM and FM
radio stations, TB stations are theoretically difficult to be assumed. It is advised that field exami-
nation of electromagnetic environment is given to evaluate the electromagnetic condition induced
by fixed RF transmitter. If the electromagnetic intensity of the RC-5000 in its use position exceeds
the abovementioned RF compatibility level, its operation under such conditions above should be
examined. If any abnormal condition is observed, an additional means, for instance, changing of
RC-5000 direction or place may be necessary.
b
150 kHz to 80 MHz The electromagnetic intensity is preferred to be not more than 3 V/m at a
frequenncy range of 150 kHz to 80 MHz.

The RC-5000 is intended to be used in the electromagnetic environments where the radiation
interference is provided. The customer or the user of the RC-5000 will be able to contribute to the
prevention of electromagnetic interference by maintaining the minimum distance between the
portable or movable type RF-communication equipment (transmitter) and the RC-5000. The
minimum distance shall be in conformance to the maximum output by communication equipment,
as recommended below.

The recommended separation distance, d, in a unit of meter (m) for a transmitter other than listed
above which is not listed, is determined by using the equations which apply for transmitter fre-
quency, where "P" is the maximum rated output of a transmitter in the unit of watts (W), which is
specified by transmitter manufacturer.
Remark 1: Higher frequency range is applicable for 80MHz and 800MHz.
Remark 2: These guidance items are not always applicable for all cases. The transmission of
electromagnetic emissions is influenced by the absorption and reflection of emissions from struc-
tural objects, physical objects, and human bodies.
