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.
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 CO

the applicable RF compliance level above, the CO

SYSTEM should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the CO
