Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, 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.

Le intensità di campo per trasmettitori fissi, come le stazioni base per radiotelefoni (cellulField strength 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 theoreti-
cally 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
UTC2
is used exceeds the applicable RF compliance level above, the
UTC2
should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
UTC2

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the UTC2
The
UTC2
is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
UTC2
can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equip-
ment (transmitters) and the
UTC2
as recommended below, according to the maximum output power of the communications equipment.
