Recommended separation distances between portable and mobile
RF communications equipment and the SoundCare™ Plus device
The SoundCare™ Plus device is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or the user of the SoundCare™ Plus device can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment
(transmitters) and the SoundCare™ Plus 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) accordable to the transmitter manufacturer.
NOTE I At 80 MHz and 800 MHz. the separation distance for the
higher frequency range applies.
