NOTE 1: At 80 MHz and 800 MHz, 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.
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 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 CMS50D+ is used exceeds the applicable RF
compliance level above, the CMS50D+ should be observed to verify
normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the
CMS50D+.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than 3 V/m.
Recommended separation distances between portable and mobile
RF communications equipment and the EQUIPMENT or SYSTEM –
output power rating of
the transmitter in watts
(W) according to the
transmitter manufacturer
and d is the
recommended
separation distance in
metres (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
