This MP3 file needs to be deleted and replaced by the MP3 file you want to play when you activate the Alert mode. The
MP3 file name is not important. But it is important that there is only one MP3 file in the Alert folder.
Check the properties of the MP3 file.
NOTE the new MP3 file cannot be “Read only”.
To check this, right click on the MP3 file and scroll down and select Properties, you will get a window that looks like figure
15.
Make sure the “Read Only” box has no tick in it.
The new MP3 is now installed on the card. Repeat these steps for the other MP3 folders if you need to.
The card can be removed from the PC following windows safe card removal procedures. Make sure the amplifier is OFF
and insert the SD card into the slot in the rear; it will click when fully inserted. The amplifier is ready to use.
