Guidance and Manufacturer's Declaration - Electromagnetic Immunity
(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 ME Equipment is used
exceeds the applicable RF compliance level above, the ME 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 ME Equipment.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1]
V/m.
Recommended Separation Distances
Recommended Separation Distance Between Portable and Mobile RF Communication
Equipment and the ME Equipment
The ME Equipment is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the ME Equipment can help
prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the ME Equipment as
recommended below, according to the maximum output power of the communication
equipment.
