Hillrom service team has identified that during an audio station's rebooting sequence, which may occur during a system upgrade/planned service event, or with an emergency power outage, where back up power is not functioning, the audio station may potentially experience an unrecoverable lost Psoc system alert which stops the audio functionality and indicates a functional error on the user interface. Error state indications display on caregiver interfaces, however in this state there is no call annunciation for the impacted location, which includes normal calls and bed exit calls and code calls.
