Operation
During a procedure, the user can access any of the functions available
in the system either through the camera head button mappings or via
the Select/Menu Access button on the front panel of the control unit.
Any settings changed during the procedure will be temporarily saved
until the system is powered down. To customize procedures and save
settings permanently, refer to the “Customize the System” section of
this manual. Refer to the menu maps for an overview of how to access
System screens.
When setup is complete and safety checks have been performed, the
System is ready for the surgeon to use. The list below sumarizes the
initial portion of the operative case:
1. Obtain a sterile camera head.
2. Plug the camera head into the control unit.
3. Connect the light guide to the appropriate light guide recepticle on
the front of the control unit.
4. Turn on the illumination by pressing the
Illumination button
5. White Balance from within the sterile field.
For detailed information about how to operate the System, read this
“Operations” section.

White Balance
To perform a White Balance, a camera head and scope must be

white object (a 4” x 4” gauze pad or flat white piece of paper) and focus
(Figure 14). Fill as much of the screen as possible with the white object,
but do not hold the scope close enough to touch the white object. Press
the White Balance button at the upper right corner of the camera head
connector (Figure 1). When the camera completes the White Balance
process, the message “White Balance Complete” appears briefly on the
screen, and a long tone sounds to indicate that the White Balance is
complete. If the White Balance fails, a chirping tone will sound.
Note: Each time the White Balance button is pressed, a single tone will
sound. Press Select to return to the MAIN MENU.
Note: When a procedure is chosen from the STARTUP screen, the
camera automatically performs a White Balance.
