A: Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and 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 device is used exceeds the applicable RF compliance level above, the device should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
the device.
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 COMMUNICATIONS EQUIPMENT AND THE DEVICE.
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The user can
help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the device as recommended below, according to the maximum output power of the communications
equipment.
