• Guidance and manufacturer’s declaration—electromagnetic emissions
The device is intended for use in the electromagnetic environments listed below, and should only be used in
such environments:
Emissions test
Compliance
Electromagnetic environment—guidance
RF emissions CISPR 11
Group 1
RF energy is used only to maintain device’s operation.
Therefore, its RF emissions are so low that it’s not likely to
cause any interference in nearby electronic equipment.

• Recommended separation distances between portable and mobile RF communication equipment and
the device.
The device is intended for use in an electromagnetic environment where radiated RF disturbances are under
control. User can help prevent electromagnetic interference by keeping the device at a minimum distance
from portable and mobile RF communications equipment (transmitters). Below table details the maximum
output power of transmitter:
