Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situations. The propagation of electromagnetic
waves is affected by absorptions and reflections of buildings, objects, and people.
a
Field strengths from fixed transmitters, e.g., base stations for radio (cellular/cordless) tele-
phones and land mobile radios, amateur radio, AM and FM radio broadcast, and TV broad-
cast cannot be predicted theoretically with accuracy. To assess the electromagnetic environ-
ment due to fixed transmitters, an electromagnetic site survey should be considered. If the
measured field strength at the location where the device is used exceeds the above compli-
ance levels, the device should be monitored to ensure proper function. If abnormal perfor-
mance is observed, additional measures may be necessary, such as re-orienting or relocating
the product.
b
Over the frequency range from 150 kHz to 80 MHz, field strengths should be less than 3 V/
m.

RF emissions acc. to CISPR 11 Group 1 The product uses RF energy only
for its internal function. Therefore,
its RF emissions are very low and
are not likely to cause any interfer-
ence in nearby electronic equip-
ment.

establishments other than domestic
and those directly connected to the
