Guidance
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.
Conducted RF

80 MHz to 2.5 GHz

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
2
, should be
less than the compliance level in each
frequency range. Interference may
occur in the vicinity of equipment
marked with the following symbol:
2. 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.
