GUIDANCE AND MANUFACTURER’S DECLARATION —
ELECTROMAGNETIC IMMUNITY (CONTINUED)
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.
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 lV 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 device is used exceeds the
applicable RF compliance level above, device should be observed to verify
normal operation. If abnormal performance is observed, additional measures may
be necessary, such as re-orienting or relocating device.
b. Over the frequency range 150 kHz to 80MHz, field strengths should be
less than 3 V/m.
