A.5.4 Annex E - Table 5
Recommended separation distances between portable and mobile RF communications
equipment and the Siaretron 4000
The Siaretron 4000 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Siaretron 4000 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Siaretron 4000 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 metres (m) can be determined using the equation applicable to the frequency of the transmitter, where
P is the maximum 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.
2. 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 40,66 MHz to 40,70
MHz.
3. An additional factor of 10/3 has been incorporated into the formulae used in calculating the
recommended separation distance for transmitters in the ISM frequency bands between 150 kHz
and 80 MHz and in the frequency range 80 MHz to 2,5 GHz to decrease the likelihood that
mobile/portable communications equipment could cause interference if it is inadvertently brought
into patient areas.
Note: the values shown in the table refer to the standard levels of the norm, 3V for V
