The following instructions describe the touch screen calibration procedure for the 500CCM. Note that there are separate instructions for recalibrating the 500CCM.

1. Connect the clock module to a PC via the USB connection, and open E-Logic.
2. Open the E-Logic design file for your system.
3. From the compile menu, select Open E-Plex interface.
4. Click on the Stop Streaming button.
5. If you have not already done so, program the clock and the LCD.
6. In the module selector area, choose (500LCD) from the drop-down list.
7. Click on the Open Module Test Program button.
8. Click on the Re-calibrate touch button.
9. Close the module test program.
10. Start streaming
11. The 500LCD display will now ask to you press on the highlighted regions. For best results you should use something hard and pointy (but not sharp).

A space is provided at the edge of the LCD to insert a printed graphic. Typically, this would include controls to switch the LCD display on and off. The 500CCM can be programmed to switch off the LCD after an amount of inactivity, but the power buttons will still be visible. This can also be used for commonly used menu functions, such as a link to the home page.
