electromagnetic site survey,
ᵃ
should be less than the compliance
level in each frequency range.

.
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 of this device is used exceeds the applicable RF compliance level above, the
models KTR-201, KTR-202, KTR-203 should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating this device.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
