22.2 Recommended separation distances between portable and
mobile RF communications equipment and BT-740
The BT-740 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the BT-740 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the BT-740 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.
