Surge Protectors

ZEISS recommends the use of surge protectors or UPS (Uninterruptible Power Supply) systems to
help isolate the HFA3 from power surges or fluctuations. Hospitals, surgery centers, and offices with
instruments which consume large amounts of power, such as surgical lasers, especially should be
careful to plug the HFA3 directly into a UPS or adequate surge protector.

Printers

The HFA3 is compatible with PostScript printers, including shared network printers and wireless
printers using a wireless USB adapter, or directly connected using the Ethernet port. Direct USB
connection is not supported.
WARNING: If any external devices are connected to the instrument, the operator
must ensure that the complete system continues to comply with the requirements
defined in IEC 60601-1.

Touch Screen

All functions can be performed by touching a command button on the touch screen. Be careful not
to press too hard against the screen. To deselect an item, touch on another area of the screen. To
return to a previous screen, if applicable, select the Back button on the lower left side.

Screen Keyboard

The screen keyboard is used to fill out the text boxes. It appears automatically as soon as the cursor
is inserted into a text box. Touch and hold a character to bring up a menu with all the special
characters (umlauts, etc.) belonging to this character. Select the desired special character by tapping
it. Not all characters on the keyboard will be associated with special characters.
