How to update firmware

Updating Firmware on Your AR5 Recorders

Updating your recorder’s firmware lets you install new features and bug fixes. It’s a quick process that only takes a few minutes.

What You’ll Need

• An SD card

• The latest firmware version - available at Firmware v1.74 for AR5 - NEW

• Batteries or a USB power cable

• Your working AR5 or AR4 units.
  

Steps to Install Firmware

1. Save the Firmware to an SD Card
    Go to alato.co.nz/firmware, download the latest version, and save it onto your SD card.
   

2. Insert the SD Card
    Place the SD card into your AR5 or AR4 recorder.
   

3. Connect Power
    Insert batteries or connect your USB power cable. Do not turn the unit on
   

4. Start the Firmware Update
    Press and hold the Right Arrow button - do not release this.
   While the Right Arrow button is pressed tap the PAGE button once to turn the unit on and you see “Flashing ARM” appear on the screen.
   
   The recorder will automatically begin updating. A percentage counter will show progress — this takes about 20 seconds.
   

5. Finish and Confirm
    When complete, the recorder will restart and display the new firmware version number.
   

Common Issues

• Unit was already ON: The update won’t start if the recorder is powered on — it will just turn on normally.
  

• Buttons not pressed together: If you don’t hold both the Page and Right Arrow buttons at the same time, the recorder will simply power up instead of updating.
