This service bulletin will summarize some of the major differences between the HFA II system and the
HFA II - i system. If you are trained on the HFA II system, the similarities between the two models are
close enough that additional classroom training is not required.

The CPU plugs into the Backplane PCB and is enclosed in an ESD enclosure. The Backplane PCB
controls the Patient Switch, Touch Screen, Camera, Frame Grabber and Video.

A new power supply is used, which has additional vcc power capacity. The HFA II and HFA II - i power
supplies are not interchangeable. The HFA II - i uses a new Motor Driver Board, which is backward
compatible to the HFA II. The back cover of the instrument has been re-designed to fit over the CPU
enclosure and provides access to peripheral connectors.
Service Changes
All calibration procedures for the HFA II - i are identical to the HFA II. The HFA II - i saves all calibrations
to the Hard Drive. The calibration file is also saved to a floppy disk and can be restored through the
calibration menu. The back cover of the instrument provides a special storage slot for the calibration
backup diskette.
The HFA II - i utilizes a new DST tool for changing the configuration of the instrument. Additionally, you
may need to change BIOS settings for future upgrades to the system. The CPU diagnostics are no longer
available; the Quick Tech 2000 Pro Tool will be used for HFA II - i CPU diagnostics.
