B2 SCREEN CALIBRATION (OFFSET CORRECTION)
This procedure ensures that the display screen image is positioned correctly, compared with the touch screen (so that
'what you touch is what you get'). The procedure, is necessary only rarely, if at all, and is included here only for the
sake of completeness.
1. At power-up, continuously hold a finger in contact with the screen until (after approximately 30 seconds) the
diagnostic display appears as shown in figure B1. Operate the Touch cal key to call the first calibration screen, as
depicted in figure B2*
2. Using a soft point (> 1mm radius) of a material which will not damage the touch screen, touch the intersection of
the upper set of crosshairs, as requested by the display and keep touching it until the next target appears..
3. Continue the process, according to the directions appearing on the screen. Once all the 'targets' have been ac-
cepted, the recorder returns to the diagnostic display.
* Note: The diagnostic display times-out (to the screen calibration page) after about 5 minutes. The screen
calibration pages time-out to the diagnostic page after a time which depends on how much of the calibration
procedure has been completed
