Portable and mobile RF communications
equipment should be used no closer to
any part of the Merlin@home transmitter,
including cables, than the recommended
separation distance.
Recommended separation distance:
(80 MHz to 800 MHz)
(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 meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey*, should be less than the
compliance level in each frequency range.
Interference may occur in the vicinity of
equipment marked with the following

*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 of the location in which the Merlin@home transmitter is used exceeds the applicable
RF compliance level above, the Merlin@home transmitter should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the Merlin@home transmitter.
Note
The Merlin@home transmitter is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The user of the Merlin@home
