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.

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.

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:

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.
