Electromagnetic environment
– guidance
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:

Not Applicable
0.01 NA
0.1 NA
1 NA

100 NA
For transmitters rated at a maximum output power not listed above,
the recommended separation distance d in metres (m) can be esti-
mated using the equation applicable to the frequency of the transmit-
ter, 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. Electro-
magnetic propagation is affected by absorption and reflection from
structures, objects and people.
