The Mediant 4000 is a fantastic all-in-one multimedia player that comes with a built-in FM radio. It’s also compatible with many other devices, such as smartphones and tablets.

However, you may find it impossible to get the Mediant working after a few years of use. The reason for this can be hardware issues or software glitches.

In this article we will show how to reset your AudioCodes Mediant 4000B so that it works again. First, let us explain what an audio code is…

What is an audio code?

An audio code is a short sequence of data that represents one song in one of two formats – MP3 or WMA. The AudioCodes Mediant 4000 only has enough space on its memory card to store a maximum of four audio codes at any time.

If you want to listen to more than four songs, you’ll need to upgrade your Mediant 4000 using external media cards.

For example, if you have a 128MB SD card, then you could store up to 16 songs (4×4 MB) on to it. If you want to store 24 songs (6×6 MB), you would need to buy an SD card with 256MB capacity. And if you wanted to store 32 songs (8×8 MB) then you would need a 512MB card.

It’s important to note here that most of the large SD cards available today are actually 4GB cards, which means they only hold the equivalent of 64 songs. This isn’t surprising when you consider the size of an audio code!

To avoid confusion, it should be noted that there is no limit on the number of songs you can store on your Mediant 4000 via audio codes. However, some users have reported problems storing more than 40 songs on their mediant 4000.

With these limitations in mind, it’s clear that you should only buy an SD card that has a minimum storage capacity of 1GB or greater.

When you connect your Mediant 4000 to your PC, it will automatically create a folder called ‘audio codes’ on your hard drive.

This folder contains every audio code that was stored on your Mediant 4000’s internal flash memory. To remove all audio codes from your Mediant 4000, follow these steps:

• Connect your Mediant 4000 to your computer using the supplied USB cable.
• Open the ‘audio codes’ folder using Windows Explorer.
• Right click inside the ‘audio codes’ folder and select Delete Folder.
• Now, open the Mediant 4000 settings menu and select Reset to Factory Defaults.
• You will see a warning message saying that certain files on your Mediant 4000 might not work once it has been reset. Click OK to proceed anyway. Your Mediant 4000 will restart itself immediately.
• Your Mediant 4000 will now display the “Initializing Firmware” screen, followed by the Mediant 4000 startup logo.

Once you hear the startup sound, press the power button on the front of your Mediant 4000 to turn it off and then on again to start up. If you hear a buzzing noise instead, try holding down the power/reset button on the back of the device until the startup sound fades away.

Finally, you can disconnect your Mediant 4000 from your PC and continue listening to your music. You may need to reconnect your Mediant 4000 to your PC before your music starts playing again.

Note: We haven’t tested whether the Mediant 4000 supports the playback of video files through audio codes. So far, we don’t think it does, but we advise you check our video recommendations page before buying your first Mediant 4000.
