When you encounter issues with abnormal touch positions on the touchscreen, you can first attempt to resolve them through touchscreen calibration. Here are the touchscreen calibration steps:
1. After starting the stereo, on the main interface of the system, press five fingers on the screen simultaneously. Wait for 4 to 6 seconds, and the system will enter the touchscreen calibration mode.
2. Click the “+” symbol in the upper - left corner, and the touchscreen calibration will be completed.
If the touchscreen problem is not resolved by following these steps, please contact Perloyal's customer service for further assistance.
