USB connection

Your radio has a USB connection to connect your PC. The usb can be 
used to copy fi les to and from your SD card and also for any software 
updates available.

When the USB connection is used to link your radio to your PC the SD 
card should appear as a removable disk drive. MP2 and MP3 fi les are 
held in a folder called "RADIO".

If your PC already has an SD card reader, you will fi nd that fi le transfer 
is faster when using this than when using the USB connection to your 
radio.

Your radio uses the FAT 16 format for storing fi les on the SD card.

1.  Lift up the right hand side rubber cover on the top of your radio and  

insert the usb cable into the slot.

2.  In DAB mode press and hold in the 

Advanced info button

 and 

rotate the 

Tuning/Record control

 until "Memory Card" is shown on 

display.

 

If in FM or Playlist mode simply press and hold the 

Advanced info 

button

 and "Memory Card" will show on display.
