rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m)�

less than the compliance level in each
frequency range�

Interference may occur in the vicinity of
equipment marked with the following
symbol:
Note: At 80 MHz and 800 MHz, the higher frequency range applies�
Note: These guidelines may not apply in all situations� Electromagnetic propagation is affected by absorption and reflection from structures, objects
and people�
a
The ISM (industrial, scientific and medical) bands 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 4,066 MHz to 4,070 MHz�
b
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2�5 GHz are intended
to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas�
For this reason, an additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for
transmitters in these frequency ranges�
Recommended separation distances between portable and mobile RF communications equipment and the Generator G11
The Generator G11 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled� The customer or the
user of the Generator G11 can help prevent electromagnetic interference by maintaining a minimum distance between the portable and mobile
RF communications equipment (transmitters) and the Generator G11 as recommended below, according to the maximum output power of the
communications equipment�
