⚠️ Important Notice: Card Insertion, Concealed Plug & OTG Setup

1. Align Micro SD (TF) Card Vertically: Always insert the Micro SD card straight and vertically into its dedicated slot with the golden contact pins oriented correctly. Any angled or forced insertion may cause the card to slip inside the casing seam or jam.
2. Concealed 2-in-1 USB-A / Micro USB Plug: The standard USB-A connector houses a concealed pull-out Micro USB plug inside. Gently push the release latch to reveal the Micro USB connector for Android devices.
3. Single Host Connection Only: Connect only one host interface (USB-C or USB-A/Micro USB) at a time. NEVER connect two computers, tablets, or phones simultaneously to prevent short-circuit damage.
4. OTG Support & Memory Card Clarification: Smartphones and tablets must support USB OTG functionality (enable "OTG Connection" in system settings if required). Memory cards are for demonstration only and are NOT included.

Frequently Asked Questions

Q: Can I read both an SD card and a Micro SD card at the same time?
A: Yes. Both slots function concurrently, allowing your computer or phone to recognize two separate drive letters and transfer files directly between the two cards.

Q: Where is the Micro USB connector located?
A: The Micro USB plug is concealed inside the full-sized USB-A connector. Simply press the blue tab on the USB-A plug forward to extend the Micro USB connector.

Q: Why is my memory card not showing up on my Android smartphone?
A: First, make sure OTG is enabled in your phone's system settings. Second, verify that the memory card is formatted in FAT32 or exFAT, as Android does not natively support NTFS-formatted storage media.
