### Important Usage & Maintenance Guidelines

To ensure optimal performance and long service life, the following precautions and troubleshooting tips should be observed:

#### 1. Surface Care

●Avoid liquids or sticky substances on the touchscreen surface, as they can cause false touch detection and calibration errors in surface acoustic wave (SAW) systems.

●Cleaning method: Use a soft, dry cloth or a lint-free cloth lightly dampened with industrial alcohol or glass cleaner. Gently wipe from the center outward to avoid streaks or damage.

#### 2. Troubleshooting Common Issues

●Slow or unresponsive touch response:

  ●Possible causes:

    ●Aging system with low internal clock frequency.

    ●Moisture or water droplets moving on the screen surface.

  ●Solutions:

    ●Upgrade or replace the system if hardware is outdated.

    ●Dry the screen thoroughly with a clean cloth to restore normal responsiveness.

●Inverted cursor movement (e.g., touching left moves cursor right):

  ●Likely cause: Connector reversed between the control box and touchscreen, or left-right orientation of the touch panel is reversed.

  ●Solution: Reconnect the cable correctly or adjust the physical mounting orientation of the touchscreen.

### Additional Notes

●No moving parts in the touch panel ensures high reliability and low maintenance.

●Safe for use in harsh environments when properly sealed and cleaned.

●Ideal for mobile diagnostic, remote control, and field operator terminals in manufacturing, packaging, and material handling systems.
