Guidance and Manufacturer's Declaration (continued)
Separation Distances
The RMU-2000 ACC is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the RMU-2000 ACC can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the RMU-2000 ACC as recommended below,
according to the maximum output of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (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: As 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 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.
Note 3: An additional factor of 10/3 is 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 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
The use of accessories other than those specified may result in
increased emissions or decreased immunity of the RMU-2000 ACC.
WARNING
Portable and mobile RF communications equipment should be used
no closer to any part of the RMU-2000 ACC, including cables, than
WARNING
necessary.
The RMU-2000 ACC should not be used adjacent to other electrical
equipment. If the situation requires that the RMU-2000 ACC be used
when adjacent with other electrical equipment, the RMU-2000 ACC
WARNING
should be observed to verify normal operation in the configuration in
which it will be used.
