Setup and Installation
Follow these steps to install your SanDisk 32GB Micro SDHC Memory Card into a compatible Roku streaming player.
- Identify the SD Card Slot: Locate the Micro SD card slot on your Roku device. For some models, such as the Roku 3, you may need to unplug the HDMI cable to access the slot.
- Insert the Memory Card: Carefully insert the SanDisk Micro SDHC card into the slot. Important: For some Roku models, the gold contacts on the card should face upwards when inserting. If the card does not slide in smoothly, gently flip it over. Do not force the card into the slot.

- Format the Card: Upon recognition, your Roku device will typically prompt you to format the memory card. Follow the on-screen instructions to allow Roku to format the card. This process prepares the card for use with your Roku player.

Troubleshooting
If you encounter issues with your SanDisk Micro SDHC Memory Card, refer to the following common solutions:
- Card Not Recognized by Roku:
- Ensure the card is fully and correctly inserted into the slot. Try re-seating the card.
- Verify the card's orientation; for some Roku models, the gold contacts should face up.
- Restart your Roku device. Unplug it from power, wait a few seconds, and plug it back in.
- Confirm your Roku model is compatible with Micro SD cards.

- This error often resolves with a simple restart of the Roku device after inserting the card.
- Ensure the card is properly seated.
- Slow Performance:
- This is a Class 4 card, designed for a minimum write speed of 4MB/s. For applications requiring higher speeds, such as recording high-resolution video or very demanding apps, a higher class card (e.g., Class 10 or U1/U3) might be necessary.

- Card Not Recognized by Computer (using card reader):
- Ensure the Micro SDHC card is correctly inserted into the Everything But Stromboli Memory Card Reader.
