Electromagnetic Immunity (continued)
Immunity test
Radiated RF
IEC/EN 61000-4-3
Conducted RF
IEC/EN 61000-4-6
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
Note 3: The RMU-2000 ACC's Essential Performance for the purposes of EMC testing is to provide chest compressions at
defined range of motion and rate. For the purposes of monitoring performance that could result in unacceptable
risk during immunity/susceptibility testing the RMU-2000 ACC shall not exceed 2.4 inches.
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.
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 RMU-2000 ACC is used exceeds the applicable RF compliance level
above, the RMU-2000 ACC should be observed to verify normal operation. If abnormal performance is observed additional
measures may be necessary, such as reorienting or relocating the RMU-2000 ACC.

Portable and mobile RF communications
equipment should be used no closer to
any part of the RMU-2000 ACC, including
cables, than necessary. The recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter is shown in the following table.
Interference may occur in the
vicinity of equipment marked
