This section documents several known behaviors and precautions in typical firmware versions to help mitigate risks in advance during device delivery and field use. Refer to the release notes provided with the product or officially published information for the definitive list of issues, and update it regularly based on the firmware version in use.

Typical Issues in Historical Versions

  • The password/unlock strategy in earlier versions was somewhat cumbersome:
    In some older versions, the screen unlock and password prompt strategy could cause prompts to appear too frequently, affecting the user experience. Later versions have been optimized while maintaining security.
  • HDMI output latency was relatively high in older versions:
    Early firmware used slightly conservative latency control for HDMI screen casting, while newer versions have delivered significant improvements through optimization.

For issues in historical versions that have been fixed in newer versions, upgrade to the target version standardized by your team as soon as conditions permit.

Safety and Usage Precautions

  • Before powering on, check the positions of the three-position switches and ensure they are set to the appropriate positions as described in the “Safety and Compliance” section;
  • Use chargers and cables that meet the recommended specifications, and avoid charging or discharging in extreme environments such as high temperatures or high humidity;
  • When planning network and data link solutions, comply with local radio and flight-related regulations to avoid noncompliant use.

General Recommendations for Routine Operation

  • Allow sufficient time for setup and rehearsal before important tasks, and avoid proceeding directly to a critical task when using the device for the first time;
  • Regularly back up critical configurations and data so that you can restore the system to a stable state more quickly if an abnormal condition occurs;
  • If you discover a potential issue that may be widespread, report it promptly through official technical support channels so that it can be improved in subsequent versions.
