Guidance and manufacturer's declaration – ELECTROMAGNETIC IMMUNITY – FOR
EQUIPMENT AND SYSTEMS THAT ARE NOT LIFE-SUPPORTING
(1)
At 80 MHz and 800 MHz, the higher frequency range applies.
(2)
Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people.
a)
Field strengths from fixed RF 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 I-TECH UE is used
exceeds the applicable RF compliance level above, I-TECH UE should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating I-TECH UE.
b)
Over the frequency range 150kHz to 80MHz, field strengths should be less than [V
Recommended separation distances between portable and mobile radio
equipment for I-TECH UE not sustaining vital functions
I-TECH UE is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of I-TECH UE can help prevent
electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and I-TECH UE 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 determined 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 80MHz and 800MHz, the separation distance for the higher frequency range applies.
(2)
These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
