<p><b>New page</b></p><div>There are minor differences between screens in the alignment of the touch sensor with the display. This is a particular problem with the small buttons on the Signal Generator, but can also cause the screen to appear unresponsive in other modes. Software release 201711031 (NOT YET RELEASED) introduces the capability to calibrate the touchscreen, to store the corrections and apply them each time the transmitter or signal generator are started up.<br />
<br />
The TouchScreen calibrator is accessed from the "Cal Tch" button on Menu 3 of the Portsdown Transmitter application.<br />
<br />
=== Usage ===<br />
<br />
After selecting "Cal Tch" an information screen is displayed explaining that 8 touches will be required.<br />
<br />
Touching the screen again shows the first cross (in the top left corner). Touch the screen at the centre of the cross. This will cause the next cross to appear (bottom left); touch that and the next cross will appear and so on. If you make a gross error (perhaps by double tapping one of the crosses) and the program senses that you have touched outside the correct quadrant for the cross, it will display an error message and ask you to start again. The stored calibration will not be overwritten.<br />
<br />
After 8 successful touches on the crosses, the display will show you the initial sensed touch positions in red, and the corrected positions in green. A further touch saves the new calibration to file and restores normal operation.</div>G8GKQ
