Recommended separation distances between portable and mobile RF
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.

Compliance
The Focus uses RF energy only for its internal function. Therefore,
Group 1
its RF emissions are very low and are not likely to cause any
interference in nearby electronic equipment.
The Focus is suitable for use in all establishments, including
Class B
domestic establishments and those directly connected to the
public low-voltage power supply network that supplies buildings
used for domestic purposes.
