Note:
The following degradations associated with essential performance were not allowed during
test: component failure, changes in programmable parameters, resets to factory defaults,
changes in operating modes, or data corruption.
Medical Electrical Equipment needs special precautions regarding EMC and needs to be installed and
put into service according to the EMC information in this manual.
Portable and mobile RF communications equipment can affect Medical Electrical Equipment.
*
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the Platform is used exceeds the applicable RF compliance level above, the Platform should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
Platform.
** Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
*** The ISM (industrial, scientific, and medical) bands between 0.15 MHz 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. The amateur radio bands between 0.15 MHz and 80 MHz
are 1.8 MHz to 2.0 MHz, 3.5 MHz to 4.0 MHz, 5.3 MHz to 5.4 MHz, 7 MHz to 7.3 MHz, 10.1 MHz to 10.15 MHz, 14 MHz to
14.2 MHz, 18.07 MHz to 18.17 MHz, 21.0 MHz to 21.4 MHz, 24.89 MHz to 24.99 MHz, 28.0 MHz to 29.7 MHz, and 50.0 MHz to
54.0 MHz.

Recommended separation distances between portable and mobile RF
communications equipment and the Platform
The Platform is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Platform can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the Platform
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
meters 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 according to the transmitter manufacturer.
Notes:
1.
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
2.
These guidelines may not apply in all situations. Electromagnetic propagations affected by absorption and
reflection from structures, objects, and people.
