during an extended power outage or
interruption, the model P1170
should be switched to operate from
the backup battery.
Note 1: UTis 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 electromag-
netic compatibility of electrical equipment at very close distances. Care should always be exercised when using any elec-
trical or RF equipment in the immediate patient area.
