Recommended separation distances between portable and mobile RF communication equipment
and MAW, Multi-zone ART Workstation
®
MAW, Multi-zone ART Workstation
®
is intended to be used in the electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of MAW, Multi-zone ART Workstation
®
can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and MAW, Multi-zone ART Workstation
®
as recom-
mended 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 dis-
tance
d
in meters (m) can be estimated 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 transmit-
ter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations.
Medical devices may be affected by cellular telephones and other personal or household
devices not intended for medical facilities. It is recommended to make sure that all equip-
ment used near the ART workstation product complies with the medical electromagnetic
compatibility standard and to check before use that no interference is evident or possible.
If the interference is suspected or possible, switching off the offending device is the normal
solution as it is the usual practice in aircrafts and medical facilities.
Medical electrical equipment is to be treated with special precautions indicated by EMC and
has to be installed and put into service according to the EMC information provided. Portable
and mobile RF communications equipment can affect medical electrical equipment.
