Appendix

Recommended Separation Distances between Portable and Mobile RF
Communications Equipment and Devices or the CR-2

The CR-2 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the CR-2 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the CR-2 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 metres (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.

NOTE 1: To maintain the optimum EMC performance, do not use cables other than supplied, nor extend the cable lengths

more than specified.
