Technical Information
This table details the recommended separation distances between portable and mobile RF
communications equipment and this device
This device is intended for use in an electromagnetic e
nvironment in which radiated RF disturbances are controlled. Users
of this device can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communication equipment (transmitters) and the device as recommended below, according to maximum output
power of the communications equipment.

For transmitters rated at a maximum output power n
ot 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.
NOTES:
1. At 80 MHz and 800 MHz, the higher frequency range applies.
2. These guidelines may not apply in all situations. Electro
magnetic propagation is affected by
absorption and reflection from structures, objects, and people.
