4) Recommended separation distances between portable and mobile RF communications
equipment and the EX PLUS 1300
The EX PLUS 1300 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the EX PLUS 1300 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the EX PLUS 1300 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.
Caution
1. At 80 MHz and 900 MHz, the separation distance for the higher frequency
range applies.
2. These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
