Subject: Vertical Lift Column Power Supply (PS3) Replacement

Affected Products: OEC® 8800; OEC® 9800; OEC® 9900 Elite

The Vertical Lift Column Power Supply (PS3) has been replaced on the GE Healthcare OEC C-arm. The
replacement PS3 fixes the root cause of the early life failure experienced with the previous version.

The new PS3 functions slightly different than the older version. After the C-arm is switched on the
vertical up or down switch must be pressed to start the full initialization of the vertical drive
functionality. This initialization takes approximately five seconds after which full vertical functionality is
enabled.

The Up and Down switches for the Vertical Lift Column operates as before and in order to protect the
power supply, a delay (0.4 second) was built into the Up command and Down command switch
operations. If the user makes a quick change between Up and Down commands, or presses the same
button quickly in succession, the respective switch will need to be released and pressed again. This
delay is normal and expected, and will protect the PS3 from failure.

The overall benefit to the new Vertical Lift Column Power Supply is the elimination of a potential Vertical
Lift Column failure that has been identified as a safety concern. The built in switch delay makes the
integrity of the PS3 consistent with the overall life expectancy of your GE Healthcare OEC C-arm, and will
eliminate the failure of the Vertical Lift Column during use.

If you have any questions or concerns regarding this issue, please do not hesitate to contact the
sales or service team for further information at 800-874-7378. Information is available at this

number 24 hours per day, 7 days a week.
