The Saver ONE P must be used in an electromagnetic environment in which radiated RF interference is controlled. The
customer or the operator of the Saver ONE P can help prevent electromagnetic interference by maintaining the
minimum distances recommended below, between the portable and mobile RF communications equipment
(transmitters) and the
Saver ONE P , based on the maximum output power of the communication devices.

For transmitters whose estimated maximum power is not listed above, the separation distance
“d” in metres (m) can be
determined using the equation that applies to the transmitter’s frequency, where P represents the maximum power produced
by th e transmitter in watt (W) in accordance with the transmitter’s manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance applied is the one used for high frequency intervals.
NOTE 2:
The ISM frequency bands (for industrial, scientific and medical application) between 150 kHz and 80
MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz and 40.66
MHz to 40.70 MHz
NOTE 3:
An additional factor of 10/3 is used in the calculation of the recommended separation distance for
transmitters in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency interval
from 80 MHz to 2.5 GHz to reduce the possibility that portable/mobile equipment can interfere, if
accidentally brought into the patient’s area.
NOTE 4:
These guidelines may not be applicable to all situations. Electromagnetic diffusion is affected by
absorption and reflected from structures, objects and people.
