EMC Information
Guidance and manufacturer’s declaration – electromagnetic emissions
The device is intended for use in the electromagnetic environment specified below. The
customer or the user of the device should assure that it is used in such an environment.
Emissions test Compliance Electromagnetic environment –
guidance
RF emissions
CISPR 11 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.
RF emissions
CISPR 11 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 buildings
used for domestic purposes.
Harmonic emissions

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 customer or the user of the device 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.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance
d in metres (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 separation distance for the higher frequency range
applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
