Portable and mobile RF communications equipment
should be used no closer to any part of the
KR/RM-9800, including clables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance
d=1,2√P
d=1,2√P 80 MHz to 800 MHz
d=2,3√P 800 MHz to 2,5 GHz
where P is the maximum output power rating of the
transmitter in watts (W) according to the
manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey a,
should be less than the compliance level in each
frequency range b.
Interference may occur in the vicinity 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 solutions. Electromagnetic propagation is affected by absorption and reflection
form structures, objects and people
a 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 cannot be predicted theoretically with accuracy. To assrss 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 KR/RM-9800 is used exceeds the applicable RF compliance level above, the KR/RM-9800 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating
the KR/RM-9800.
b Over the frequency range 150 kHz à 80 MHz, field strengths should be less than 3 V/m.
Recommanded distance between the device and portable or mobile frequence emmision communication devices.
The device is intended to be used in electromagnetic environments where the interference resistance is controlled.
Buyer or user can keep the minimum distance between the device and the portable or mobile commnumcation
