yield roughly 720 printouts. Thermal paper may be ordered from Carl Zeiss Meditec Parts
Department. The item Part Number for thermal paper is 2660100024433.
Hint: For thermal printouts of exam data that you wish to have a very long shelf life, make and file a
photocopy of the printout, shortly after it is thermally printed.
Touch Screen Calibration
Maintaining proper calibration of the touch screen is critical. The touch screen is calibrated properly
if the screen recognizes the location where your finger touches the screen and responds
appropriately. For example, when accessing the Main Menu, if you select RECALL LAST TEST and the
instrument responds as if you selected SHOW TEST LIBRARY, the touch screen is not calibrated
correctly.
Note: In addition to the standard calibration method that follows below, there are two additional
ways to re-calibrate the touch screen should you have difficulty getting to the TOUCH SCREEN
CALIBRATION button on the Additional Setup Screen. These two alternative methods are presented
here, following the standard calibration method.
Standard Touch Screen Calibration
The touch screen’s response may drift periodically. If errors occur, follow this standard procedure or
one of the alternative methods that follow this section:
1
Go to the Main Menu and press the
SYSTEM SETUP
icon.
2
Press ADDITIONAL SETUP.
3
Press TOUCH SCREEN CALIBRATION.
4
Verify that you wish to calibrate the touch screen by selecting CONTINUE.
5
Follow any screen instructions. Using the eraser end of a pencil, touch the square in the upper
left-hand corner of the screen, keeping the alignment of the pencil perpendicular to the screen.
6
When prompted, touch the square in the lower right-hand corner, again keeping the pencil
perpendicular to the screen.
7
You will return to the Additional Setup screen. With your finger, touch the screen in several
locations to determine whether it is calibrated properly.
8
If the touch screen response still is not accurate, re-calibrate by repeating steps 1 through 7.
