Guidance and Manufacturer's Declaration - Electromagnetic Immunity
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
(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 ME
Equipment is used exceeds the applicable RF compliance level above, the ME Equipment
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the ME
Equipment.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1]
V/m.
Recommended Separation Distances
Recommended Separation Distance Between Portable and Mobile RF Communication
Equipment and the ME Equipment
The ME Equipment is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the ME Equipment
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the ME
Equipment as recommended below, according to the maximum output power of the
communication equipment.
