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 bro-
adcast 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 model Medel Check is used exceeds the applicable RF compliance level above,
the model Medel Check should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting
or relocating the model Medel Check.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
[V1] V/m
Recommended separation distances between portable and mobile RF
The model Medel Check is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the model Medel
Check can help prevent electromagnetic interference by maintaining a minimum distan-
ce between portable and mobile RF communications equipment (transmitters) and the
model Medel Check as recommended below, according to the maximum output power
Rated maximum
output power of
transmitter
For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for 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.
