distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey a , should be less than the
compliance level in each frequency range.
b
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 radio, 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 equipment is used exceeds the
applicable RF compliance level above, the equipment should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the equipment.
b. Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distances between Portable and Mobile RF
Communication Equipment and the Lode equipmentr
TheLode equipment is intended for use in the electromagnetic environment on which radiated
RF disturbances are controlled. The customer or the user of theLode equipment can help
prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the Lode equipment as
recommended below, according to the maximum output power of the communications
equipment.
