A. The interface between the PATIENT physiological signal simulation, if used, and the ME EQUIPMENT or ME SYSTEM shall
be located within 0,1 m of the vertical plane of the uniform eld area in one orientation of the ME EQUIPMENT or ME
SYSTEM.
B. ME EQUIPMENT and ME SYSTEMS that intentionally receive RF electromagnetic energy for the purpose of their operation
shall be tested at the frequency of reception. Testing may be performed at other modulation frequencies identied by
the RISK MANAGEMENT PROCESS. This test assesses the BASIC SAFETY and ESSENTIAL PERFORMANCE of an intentional
receiver when an ambient signal is in the passband. It is understood that the receiver might not achieve normal
reception during the test.
C. Testing may be performed at other modulation frequencies identied by the RISK MANAGEMENT PROCESS.
D. Applies only to ME EQUIPMENT or ME SYSTEMS with magnetically sensitive components or circuitry.
E. During the test, the ME EQUIPMENT or ME SYSTEM may be powered at any NOMINAL input voltage, but with the same
frequency as the test signal (see Table 1).
F. Before modulation is applied.
G. This test level assumes a minimum distance between the ME EQUIPMENT or ME SYSTEM and sources of power frequency
magnetic eld of at least 15 cm. If the RISK ANALYSIS shows that the ME EQUIPMENT or ME SYSTEM will be used closer
than 15 cm to sources of power frequency magnetic eld, the IMMUNITY TEST LEVEL shall beadjusted as appropriate for
the minimum expected distance.

RF Emissions
CISPR 11
Group 1
The ME equipment uses RF energy only for its internal function. Therefore,
its RF emissions are very low and are not likely to cause any interference in
nearby electronic equipment.
