Recommended separation distances
Medical devices may be affected by cellular telephones and other personal or household
devices not intended for medical facilities. It is recommended that all equipment used
near the Multi-zone ART workstation product comply with the medical electromagnetic
compatibility standard and to check before use that no interference is evident or possi-
ble. If interference is suspected or possible, switching off the offending device is the usual
solution required in aircraft and medical facilities.
According to the EMC information, medical electrical equipment needs special precau-
tions regarding EMC and needs to be installed and put into service. Portable and mobile
RF communications equipment can affect medical electrical equipment.
Recommended separation distances between portable and mobile RF communication equipment
and the Multi-zone ART Workstation
The Multi-zone ART Workstation
is intended for use in the electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the Multi-zone ART Workstation user,
can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF com-
munications equipment (transmitters) and the Multi-zone ART Workstation
as recommended below ac-
cording 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 transmitter
manufacturer.
NOTE 1:
At 80 MHz and 800 MHz, the higher frequency range's separation distance applies.
NOTE 2:
These guidelines may not apply in all situations.
