Four views of the Iyalezirk XY6509S showing the screen rotated at 0, 90, 180, and 270 degrees — **Figure 4:** The XY6509S module demonstrating its 360-degree screen rotation capability. The display can be oriented in four directions (0°, 90°, 180°, 270°) by long-pressing the SW button, allowing for versatile placement and viewing.

To rotate the screen, press and hold the SW button on the home screen. The display will cycle through four orientations (0°, 90°, 180°, 270°).

4.4 Data Group Management and System Settings

Screenshots showing locking function, quick data group retrieval, and system parameter settings on the Iyalezirk XY6509S — **Figure 5:** This image illustrates three advanced functions of the XY6509S: the locking function to prevent accidental changes, the method for quickly recalling saved data groups, and the process for setting system parameters via the right status bar. Each function is shown with its corresponding screen display.

Locking Function: Long press the encoder key for more than 2 seconds to lock the device and prevent misoperation. To unlock, press and hold the encoder key for more than 2 seconds.
Quickly Retrieve Data Group: Long press the V-SET button to bring up the pop-up window for data group retrieval. Rotate the encoder to select the desired group. Hold down I-SET or press SW/Encoder to retrieve the selected data group.
Quickly Set System Parameters: On the main interface, press the SW button to select the status bar parameter. Rotate the encoder to switch the parameter to be set. Press SW or the encoder button to bring up the parameter setting interface. Adjust parameters by rotating the encoder. If no operation occurs for more than 6 seconds, the system will automatically exit and save settings.
