portable and mobile RF communications equipment and the Focus
The Focus is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
Focus can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Focus 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 meters (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.
Guidance and manufacturer's declaration - electromagnetic emissions

Electromagnetic Environment guidance
The Focus 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.
Group 1
The Focus is suitable for use in all establishments, including domestic establishments and
Class B
those directly connected to the public low-voltage power supply network that supplies
buildings used for domestic purposes.
