This is the Jabra BT620s USB upgrade software. What this software does is basically it will update the firmware inside your Jabra BT620s to a newer version using USB cable.

New features with the new firmware

  1. Fixes the reconnection problem with LG and Motorola phones.
  2. Improved echo control for better audio quality.
  3. Improved the DSP algorithm to fix the static/buzz experienced sometimes when streaming music from a BT stereo phone.

You must read the included Jabra BT620s.pdf file carefully before running the USB software update. The PDF contains useful information regarding the new firmware flashing and a slightest error will probably render your Jabra BT620s useless. So beware.

USB Update Software Installation Steps

  1. Do not remove your Jabra BT620s during the installation process
  2. Connect the Jabra BT620s with the PC, using the USB cable.
  3. To update your software unzip the attached software, then save to your Desktop.
  4. Place headset in the [Software download mode] using the following procedure:
    1. Press and hold the [Play] and [next track] buttons at the same time.
    2. Continue to hold the buttons until the light in either left or right turns green.
  5. Click Next to upgrade your software.
  6. The wizard will now upgrade your headset automatically. Your Jabra BT620s headset is ready for use when the window says:

    [Successful upgrade]

One thing I found funny about the BlueCore Device Firmware Upgrade Wizard, saturn-1-31-0.exe is that when check with Windows Explorer on the exe property, it says:

Internal CSR development version built on 23:Jun:04 - not for release

under the Special Build Description. Nothing major but I think you should know this before proceed with the USB software update.
