Step 4: Open folder named "trig1" you
should get a window that looks like figure 4.
Step 5: You should see an MP3 file
XXXXXX.MP3 if you have never changed the
trigger1 MP3 file then it will be named
Trigger1.MP3.
This MP3 file needs to be deleted and
replaced by the MP3 file you want to play
when you activate trigger1. The MP3 file
name is not important only that there is one
MP3 file in the trig1 folder. Make sure you
delete the old MP3!
The folder should look something like figure
5 where the MP2 file has been replaced with
Newtone.MP3.
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 6. Make sure the "Read Only"
box has no tick in it.
The new MP3 is now installed on the card and the card can be re-
moved from the PC following windows safe card removal procedures.
Make sure the A 1720B is OFF and insert the Micro SD Card back
into the Micro SD slot; it will click when fully inserted. The A 1720B is
ready to go on Trigger1.
Repeat these steps for Trigger2 to Trigger8 if you need to.
