Configuring the ClearChart 4P
(continued)
SWAP ODD/EVEN LINES
This menu setting allows for the reversal of left and right images and the direction of stereo displace-
ment. The options using the RIGHT arrow button are "Swap" and "No Change". This option accom-
modates the two different sets of polarization lenses with reversed orientation in the Auto Phoroptor
VRx. The default is No Change.
SCREEN SAVER
The ClearChart software displays a screen saver which will show a floating image when active. Either
the default ClearChart image contained in the software or a user loaded screen saver image can be
loaded.
The ClearChart has an option to adjust the length of time the Screen Saver is active. The MIN (de-
crease) and MAX (increase) buttons are used to change the time the Screen Saver is active. After
setting the preferred time, press the DOWN arrow to finalize the selection.
After the screen saver has been active for the default 30 minutes or the preferred time entered, the dis-
play will show a black screen to extend the lifetime of the display. Pressing any button will re-activate
the screen.
MADDOX LIGHT ADJUSTMENT
CAUTION: DO NOT ADJUST THE BACKGROUND ILLUMINATION. BACKGROUND ILLUMINATION
SHOULD BE ADJUSTED ONLY BY A TRAINED TECHNICIAN AND WITH THE USE OF A LIGHT ME-
TER TO VERIFY CALIBRATION OF ILLUMINATION LEVELS.
The Maddox LED light intensity can be adjusted by accessing the default settings of the instrument.
While in the start-up mode, (blue splash screen with image of the eye), press the EDU and the
MENU button in sequence to access the factory default settings. Use the DOWN arrow to advance
through the menu selections to reach the Brightness settings. Press the RIGHT arrow button to
select Recalibrate and the DOWN arrow to display the Brightness setting screen. Use the two
center buttons at the top of the remote (labeled .2 and .5 in Linear Decimal, 200 and 60 in Snellen,
and .1 and .32 in Decimal LogMAR) to increase or decrease the brightness of the Maddox light. The
number in the left corner of the screen indicates the brightness on a scale of 1 to 128. The default
setting is 45. Press the down arrow to exit the factory default settings.
