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/or 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
LS7700 Light Source
is used exceeds
the applicable RF compliance level above, the
LS7700 Light Source
should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the
LS7700 Light Source
.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
