IEC Alarms Upgrade To comply with the IEC 60601-1-8 Edition 2.1 standard, GE Healthcare has made changes to the way alarm conditions are signaled both visually and audibly to the operator on Giraffe™ and Panda™ Warmer products. Note: No changes were made to alarm definitions, alarm triggers, durations for which the alarm can be silenced, or how the alarms are terminated.

Alarm Changes The following changes have been made to the way alarm conditions are signaled visually and audibly to the operator: •

The red alarm light has changed to a white device indicator light.

The graphical user interface (GUI) has changed to indicate the priority of alarm conditions (see also Figure 1).

Figure 3. Priority of Alarm Conditions • •

The auditory alarm signals have been updated to improve spacial localization. The white device indicator light helps the operator to locate the specific device with an alarm condition (see Figure 2).

All visual and audible alarm signals are compliant with IEC 60601-1-8 Edition 2.1.
