2.1 Connecting to an iPhone

1. Locate the Lightning connector on the U Disk.
2. Insert the Lightning connector firmly into your iPhone's charging port.
3. Upon connection, your iPhone may prompt you to install a dedicated app (e.g., "i-USB-Storer" or similar, specific to Baseus products) for file management. Follow the on-screen instructions to download and install the recommended app from the App Store.
4. Once the app is installed, open it to access and manage files on the U Disk.

2.2 Connecting to an Android Device

1. Locate the USB-A connector on the U Disk. Depending on your Android device, you may need an OTG (On-The-Go) adapter if your device does not have a standard USB-A port.
2. Insert the USB-A connector (or adapter) into your Android device's USB port.
3. Your Android device should automatically detect the U Disk as external storage. You can access it through your device's file manager application (e.g., "Files," "My Files," or similar).

1. Locate the standard USB-A connector on the U Disk.
2. Insert the USB-A connector into an available USB port on your computer.
3. The U Disk will appear as a removable drive in "My Computer" (Windows) or "Finder" (macOS).

3. Operating Instructions

3.1 File Transfer

To transfer files, simply drag and drop them between the U Disk and your connected device's internal storage or other external storage locations using the respective file management application.

• Copying Files: Select the files you wish to copy, then choose the "Copy" option. Navigate to the destination folder on the U Disk or your device, and select "Paste."
• Moving Files: Select the files you wish to move, then choose the "Move" or "Cut" option. Navigate to the destination folder, and select "Paste."
• Deleting Files: Select the files you wish to delete and confirm the deletion.

3.2 File Management App (for iOS)

The dedicated app for iOS devices provides features such as:

• Direct photo/video backup from your iPhone to the U Disk.
• Playing media files (music, videos) directly from the U Disk without transferring them to your iPhone.
• Document viewing and management.
• Password protection for specific files or the entire U Disk (if supported by the app).

3.3 Safely Ejecting the U Disk

Always safely eject the U Disk from your computer or Android device before physically removing it to prevent data corruption.

• Windows: Right-click on the U Disk icon in "My Computer" or the system tray, and select "Eject."
• macOS: Drag the U Disk icon from the desktop to the Trash, or click the Eject icon next to the drive name in Finder.
• Android: Go to Storage settings, find the U Disk, and select "Eject" or "Unmount."
• iOS: The app typically manages the connection; simply close the app and disconnect.

4. Maintenance and Care

• Keep the U Disk away from extreme temperatures, direct sunlight, and high humidity.
• Avoid dropping the device or subjecting it to strong impacts.
• Clean the connectors gently with a dry, lint-free cloth if necessary. Do not use liquid cleaners.
• Ensure the protective caps (if any) are in place when not in use to prevent dust and debris from entering the connectors.

5. Troubleshooting

5.1 U Disk Not Detected

• Check Connection: Ensure the U Disk is firmly inserted into the port.
• Try Another Port/Device: Test the U Disk on a different USB port or another compatible device to rule out port issues.
• Restart Device: Sometimes, a simple restart of your phone or computer can resolve detection issues.
• iOS App: For iPhones, ensure the dedicated file management app is installed and open.
• Android OTG: For Android, verify that your device supports OTG and that the OTG function is enabled in settings if required.

5.2 Slow Transfer Speeds

• File Size/Type: Transferring many small files can be slower than transferring a few large files.
• USB Version: Ensure you are using a USB 3.0 port on your computer for optimal speeds if the U Disk supports it (though not specified, common for flash drives).
• Background Processes: Close any unnecessary applications running in the background on your device.

5.3 Data Corruption/Loss

• Safely Eject: Always safely eject the U Disk before removal.
• Backup Data: Regularly back up important data from the U Disk to another storage device.
• Avoid Interruption: Do not disconnect the U Disk during file transfer.
