Using an SD memory card with your radio
An SD card can be used in your radio for recording, playing back previously recorded radio programs, or playing back MP2/MP3/WMA fi les transferred from a PC.
Depending on the radio station a 512MB SD card will give typically 8 - 16 hours of recording time. If you are using a new SD card ensure that it is formatted correctly (see page 28)
Many different brands and capacities of SD card are available. Your RD-41 can use cards up to 2 GB. However, there are many different card variants available and not all cards can be guaranteed to work in the RD-41. In this application there is no performance benefi t in using high-speed cards. Note that the RD-41 is not compatible with very high capacity cards using the SDHC standard.
