B1.4.1 Touch screen calibrate
This key initiates the display calibration (offset correction) procedure. 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. Operate the 'Touch Screen Calibrate' key to call the fi rst calibration screen, as depicted in fi gure
B1.4.1
2. Using the stylus, 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 accepted, the recorder returns to the diagnostic display.

B1.4.2 Touch screen verify
This allows the user to check the accuracy of the touch screen without having to carry out the calibration
procedure described above.
Touching the screen with the stylus produces a crosshair at the position the recorder believes the screen
to have been touched. It is up to the user to decide if the response is good enough for recorder opera-
tion. After a few seconds of non-operation, the recorder returns to the top level touch screen display
(fi gure 1.4).
B1.4.3 Main menu
Touching this returns the user to the top level diagnostics screen (
