Recommended separation distances between
portable and mobile RF communications equipment and the ri-‐focus LED, clar N LED.
Theri-‐focus and clar N is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the ri-‐focus and clar N can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the ri-‐focus, clar N 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
inmetres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is
themaximum 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
andreflection from structures, objects and people.
