communication equipment and Accella™ Therapy device –for the Accella™ Therapy device
Recommended separation distances between portable and mobile RF communications
equipment and the
Accella™ Therapy
The Accella™ Therapy device is designed for use in an electromagnetic environment in which
interference due to radiated RF is monitored. The customer or user of the Accella™ Therapy
device can contribute to the prevention of electromagnetic interference by keeping the
Accella™ Therapy device at the recommended distances from portable and mobile RF
equipment (transmitters) as shown below, according to the maximum power output of the
communication equipment.

For transmitters with a maximum transmitting power not given above, the recommended
separation distance in meters (m) can be estimated by using the equation applied to the
transmitter frequency, where P is the maximum transmitting power of the transmitter in Watts
(W), according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the highest frequency range
applies.
NOTE 2: These directives cannot be applied to every situation. The propagation of
electromagnetic waves is affected by absorption and reflection due to structures, objects and
persons.
