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

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters
(m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all instances. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
