ANNEX E: Table 5

Recommended separation distances between portable and mobile RF communications
equipment and the Morpheus.
The Morpheus is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Morpheus can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the Morpheus 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 :
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
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.
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 V1 and 10V for V2
