The model 245 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled� The customer or the user of the model 245 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the model 245 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�
