First download the sound file.
Plug in your USB to your Speaker, and to your computer.
then im going to imagine you know how to do this but im going to list it anyhow.
Right click on the drive for your Ecaller, Probably "Removeable disc F:"
This opens window showing all the folders on your Ecaller, Right click in an empty area, slide mouse down to new and select "folder"
Now right click and rename your new folder.
open that folder.
navigate to the sound file on your computer, you should have saved it to music or someplace like that, drag and drop it in the new empty folder on your ecaller.
after it transfers, Right click on the sound file (In the folder on your caller) and click "Properties"
you get this box
Leave the name. Click the tab "Details"
Remove the text in all these areas, click apply, click OK
now disconnect speaker from your computer, BE SURE you do this properly, bottom right, in the task bar (where your clock shows), click the icon for your USB storage device and click "Safely Remove mass storage device" or something like that...if you just simply shut it off or unplug it you can corrupt the memory in your speaker unit and it will be ruined, you will know its safe when a box pops up telling you it is safe to remove.
once you have it unplugged turn off the speaker, then turn the speaker back on and turn on the remote, Wait for it to Synchronize with the remote..this step can take up to 10-15 minutes or more. Once its done you should be able to find it and its name will show up properly, your done.
When you get your Dogg caller, if you are not comfortable you can PM me and ill give you my cell number and i can walk you through it step by step no problem.
