Firmware is the software that runs on your device and Titley Scientific is continually improving this software to add features and address performance issues. It is vital that you install new updates as soon as they become available to ensure your device runs smoothly. Follow the instructions below to update the firmware on your Chorus.

How to Apply the Firmware Update

The Chorus firmware is updated using an SD card with the update copied onto it.

Step 1

Download the Chorus update file HERE. Copy it to the root directory (i.e. not in any folder) on an SD card. Make sure the file is named chorus.adx. You can use the same SD card to update multiple recorders.

Step 2

Insert the SD card and fresh batteries into your device and then turn it on.

An on-screen message will appear after a few moments: Update available. Select ✓ (left soft key) to start the update.

Do not remove the batteries or power off the recorder while the update is being installed. The Recording Mode LEDs will cycle to indicate the update is occurring and the unit will restart upon completion.

If this message does not appear then the update file wasn’t copied onto the card correctly or the firmware is already up to date. You can check the installed firmware version in the Info screen on your Chorus.

Please note the device will not update firmware if a low battery warning is displayed.

Step 3

You can now delete the update file from the SD card or use the card again to update several devices.
