Mains power quality
should be that of a typi-
cal commercial or hospi-
tal environment. If
operation is necessary
during an extended
power outage or inter-
ruption, the Basic
Care™ Bed should be
switched to operate 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/portable 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.
