Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. The electroma-
gnetic propagation is affected by absorption and reflection by structures,
objects and people.
a: Field strengths of fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM broadcast and television transmission, cannot be theoretically
predicted with accuracy. To evaluate the electromagnetic environment
based on fixed RF transmitters, an electromagnetic assessment should be
considered. If the measured field strength at the location where the ri-pen
is used exceeds the above-mentioned RF degree of compliance, the ri-pen
should be observed to ensure normal operation.
If abnormal performance is observed, additional measures may be requi-
red, such as reorienting or moving the ri-pen.
b: With a frequency range of 150 kHz to 80 MHz, the field strengths should
be less than 3 V/m.
