communications
equipment should be used
no closer to any part of the
product, including cables,
than the recommended
separation distance
calculated from the
equation applicable to the
frequency of the
transmitter. Recommended
separation distance PVd]5.3
[ 1 = PEd]5.3 [ 1 = 80 MHz to
800 MHz PEd]7[ 1 = 800 MHz
to 2.5 GHz 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
metres (m).b 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 central frequency of 80 MHz and 800 MHz, the formula for higher
frequency band shall be used.
Note 2: These guidelines may not be suitable for all situations. Electromagnetic
propagation is affected by absorption and reflection from buildings, objects,
and humans.
a. Fixed transmitters, such as base stations for wireless (cellular/cordless)
phones and terrestrial mobile radios, service radios, AM and FM radio
broadcasts, and TV broadcasts, of which the field strength cannot be
accurately predicted in theory. In order to assess the electromagnetic
environment of fixed radio frequency transmitters, electromagnetic field
surveys should be considered. If the measured field strength of the place
where this product is located is higher than the above applicable RF
compliance level, the product should be observed to verify that it can operate
normally. If abnormal performance is observed, supplementary measures may
be necessary, for example, reorienting or relocating the product.
b. In the entire frequency range of 150 kHz ~ 80 MHz, the field strength should
be lower than [3] V/m.
