Table 4: Recommended separation distances between portable and mobile RF communications
equipment and the model SR TL 1
portable and mobile RF communications equipment and the model SR TL 1
The model SR TL 1 is intended for use in electromagnetic environment in which radiated RF disturbances is
controlled. The customer or the user of the model SR TL 1 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the model SR TL 1 as recommended below, according to the maximum output power of the communica-
tions 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) accordable 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 absorpti-
on and reflection from structures, objects and people.
