RECOMMENDED SEPARATION DISTANCES FOR
COMMUNICATIONS EQUIPMENT
The LifeCare XLM with DataPort is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The recommendations provided in
Table A-4, Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and the LifeCare XLM with DataPort
help the user of the
LifeCare XLM with DataPort to prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the LifeCare XLM with DataPort, according to the maximum output
power of the communications equipment

Note: At 80MHz and 800 MHz, the separation distance for the higher frequency range
applies.

Note: The ISM (industrial, scientific and medical) bands between 150 kHz and 80
MHz are 6.765 MHz to 6.695 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283
MHz; and 40.660 MHz to 40.700 MHz.

Note: 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 80MHz
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: These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structure, objects and people.

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.
