Mains power quality should
be that of a typical
commercial or hospital
environment. If operation is
required during an
extended power outage or
interruption, 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 or 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.
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The Basic Care™ Bed is intended for use in the electromagnetic environment specified
below. The customer or the user of the bed should make sure it is used in such an
environment.
