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 Medel Professional is used exceeds the applicable RF compliance level abo-
ve, the Medel Professional should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as re-orienting or relocating the Medel
Professional.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the Medel Professional including cables, than

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 consi-
dered. If the measured field strength in the location in which the Medel Professional is used
exceeds the applicable RF compliance level above, the Medel Professional should be obser-
ved to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the Medel Professional.

Recommended separation distances between portable and mobile RF
communications equipment and the Medel Professional
The Medel Professional is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Medel Pro-
fessional can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters)
and the Medel Professional as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in metres (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.
