NOTA 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTA 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 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 applica-
ble 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 reorienting or relocating the device.
Compliance Electromagnetic environment – guidance
Group 1 The device uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely
to cause any interference in nearby electronic equipment.
Class B The device is suitable for use in all establishments, including
domestic establishments and those directly connected to the
public low-voltage power supply network that supplies build-
ings used for domestic purposes
