Introduction
This manual provides instructions for the proper use and maintenance of your Transcend 4GB Secure Digital High Capacity (SDHC) Memory Card. This memory card is designed for use with compatible devices, such as the Panasonic HDC-SD9 Camcorder, to expand storage capacity for digital media.

Image: A Transcend 4GB SDHC memory card. The card is blue with a multi-colored, red, and green label. The label prominently displays 'Transcend', 'LOCK', 'SDHC', '4GB', and a circular speed class '4' icon. A small yellow lock slider is visible on the left side of the card.
Setup
Inserting the Memory Card
- Locate the memory card slot on your compatible device (e.g., Panasonic HDC-SD9 Camcorder). Consult your device's instruction manual for the precise location and orientation.
- Ensure the memory card is oriented correctly. The metal contacts on the card should align with the contacts inside the device's slot.
- Gently push the memory card into the slot until it clicks securely into place. Avoid applying excessive force.
Lock Switch Function
The Transcend SDHC memory card features a write-protect lock switch located on its left side. When this switch is in the 'LOCK' position (slid downwards), the card is write-protected, meaning data cannot be written to, deleted from, or modified on the card. To enable writing or deleting data, slide the switch upwards to the 'UNLOCKED' position.
Operating
Data Storage
Once properly inserted and recognized by your device, the 4GB SDHC memory card can be utilized to store various types of digital data, including photographs, video recordings, and audio files. The card provides approximately 4 gigabytes of storage capacity.
Data Transfer
To transfer data to or from the memory card, connect your device to a computer or use a compatible external card reader. Follow the data management procedures outlined in your device's or computer's operating system instructions.
Speed Class
This memory card is rated as Speed Class 4, which guarantees a minimum write speed of 4 MB/s. This speed class is suitable for standard definition video recording and continuous shooting of still images on compatible devices.
Maintenance
- Keep the memory card clean and free from dust, dirt, and moisture.
- Avoid touching the metal contacts on the card to prevent static discharge or contamination, which can affect performance.
- When not in use, store the card in a protective case to prevent physical damage from drops or scratches.
- Do not expose the card to extreme temperatures (hot or cold) or strong magnetic fields, as this can lead to data loss or card malfunction.
Troubleshooting
Card Not Recognized
- Ensure the card is fully and correctly inserted into the device's memory card slot.
- If you are attempting to write data, verify that the lock switch on the side of the card is in the 'UNLOCKED' position.
- Confirm that your device is compatible with SDHC (Secure Digital High Capacity) memory cards. Older devices may only support standard SD cards.
- Try inserting the card into another compatible device or a different card reader to determine if the issue is with the card or the original device.
Data Corruption
- Always safely eject or unmount the memory card from your computer or device before physically removing it.
- Avoid removing the card during active data transfer, recording, or playback operations.
- If data corruption occurs frequently, consider formatting the card (note: this will erase all data) or replacing it if the problem persists.
