The power frequency magnetic field
should be measured in the intended instal-

low.

Mains power quality should be that of a
typical commercial or hospital environ-
ment. If operation is required during an
extended power outage or interruption, the
model P1170 should be switched to oper-
ate from the backup battery.
Note 1: U
T
is the AC mains voltage prior to application of the test level.
Note 2: The compliance levels in the ISM frequency range 150 kHz to 2.5 GHz are intended to decrease the likelihood that mobile/por-
table communications equipment could cause interference if it is inadvertently brought into the patient area. However, emission limits,
IEC 60601 test levels, and tests specified in IEC 60601-1-2:2001 do not address electromagnetic compatibility of electrical equipment at
very close distances. Care should always be exercised when using any electrical or RF equipment in the immediate patient area.
