Redback® A 4574 Alert/Evac/Chime Tone Generator
The contents of the Micro SD Card include a Library folder of sample MP3 files and five folders for the MP3 files associated
with the various functions of the A 4574.
There should be default MP3 files included in each folder. These will need to be replaced with your own MP3 files.
Open the folder in which you want to install an MP3 (in our case its the Alert folder) and you should see an MP3 file which
is named Alert.MP3 as shown in figure 7.
Fig 7.
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 8.
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.
Step 7: The card can be removed from the PC following windows safe
card removal procedures. Make sure the A 4574 is OFF and insert the
Micro SD card into the slot in the front; it will click when fully inserted.
The A 4574 is ready to use.
