Paradigm P-LCD Touchscreen Calibration
Determine the firmware version of your P-LCD or P-TS7 touchscreen:
This process will require using a paperclip, pen, or other small utensil.
- Tap the Mode button (see green rectangle in image below) on the bottom edge of the screen to go to the Setup menu. On a wall-mount touchscreen this is accessible after removing the screen from the wall. Portable wired touchscreens have a door below the display that hinges toward you to reveal the buttons and LEDs. The wireless handheld P-LCD has a plastic door that opens at the top (thinner edge, opposite the power button), after which you tilt the antenna up to access the button.
- Press the {About} button in the top left corner if not already selected
- There are separate instructions below, depending on which hardware model and which firmware version it’s running. The model type is on a sticker found on the back of the touchscreen.
Calibrate P-LCD (all versions) & P-TS7 touchscreens in firmware versions 2.1.3 and lower:
This process will require using a paperclip, pen, or other small utensil.
- Press and hold the recessed Mode button (see green rectangle in image below) on the bottom edge of the screen for 5 seconds.
- A white screen with a + symbol will show up in the top left corner. Tap it with your finger or stylus, and repeat for the other four that subsequently pop up after each press.
- After the fifth + use your finger to draw on the screen and verify the calibration is correct.
- Press {Clear} to clear the drawings you make on the screen, {Recalibrate} to start the process over if it still is not correct, or {Close} to return to your configuration, or the Setup menu.
Calibrate P-TS7 in firmware versions 3.0.0 thru 3.1.1:
In Paradigm 3.0.0 we introduced gestures to P-TS7 hardware, which requires a thin band of pixels on the outside edge of the screen to detect those movements. The way of calibrating touchscreens in software versions lower than 3.0.0 has enough variability that the calibration may cause that thin band of pixels to be missing from the screen.
To properly calibrate in 3.0.0, follow the steps in the previous instructions, and then follow the instructions below:
- Tap the Mode button to go to the Setup menu.
- Press {Screen} screen button and then press {Calibrate Touchscreen} in the bottom left of the screen. You’ll see a screen much like the previous instructions, however there is no + symbols to touch.
- Press {Default} to use the calibration ETC has programmed at the factory, and then {Accept} to return to the Setup menu.
- Press {OK} in the bottom right to return to normal operation of the screen.
Calibrate P-TS7 in firmware 4.0.0 or higher
In Paradigm 4.0.0 we removed the ability to calibrate the P-TS7 touchscreens in the field. The factory sets the calibration during manufacturing, and much like your cell phone or home tablet, never should need to be calibrated again. Instead of a {Calibrate Touchscreen} button in the Setup menu, you'll see a {Test Touchscreen} button, which goes to a white screen with a {Close} button. This utility is great for verifying that it takes touch properly. Pushing and holding the Mode button will also get you access to the test screen.
