If you have stored some presets but wish to assign the stored stations to another preset number, you can do so by following these steps:
Select the preset you want to move. You should hear the selected station in the background
Press and hold the Mode/Store button for about 1 second until “Memory…” shows in the display.
Use the skip forward/skip backward buttons to select the preset number you wish to allocate to the current station.
Press the Mode/Store button again to save your selection and return to normal mode
Note: following the long press of the Mode/store button, you must begin to make your selection quickly (within 2 seconds) otherwise, normal mode will automatically resume.
