GUIDANCE AND MANUFACTURER’S DECLARATION
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile 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 ReliOn
TM
HEM-741CRELN4 is used exceeds the applicable RF compliance level
above, the ReliOn
TM
HEM-741CRELN4 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the ReliOn
TM
HEM-741CRELN4.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2 : These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects, and people.
