Does anybody have the instructions for updating the firmware? I have 1.50 on a USB key, but I forget the key combinations I need to do. Any instructions would be appreciated. Currently I'm running 1.41. Cheers.
Hello Sonic Defender
The M51 Firmware update instruction PDF is provided with the update in the same zip file that you download from NAD website.
and to make it easier for you:
first you go here and download the update
http://nadelectronics.com/download-agree/141204162109-Software-M51-SB201402-Web.zip%7CM51-software-upgrade-V1_50
by clicking on agree at the end of the page
1. Download and save the NAD provided zip file to your computer. Unzip the file, extract and store the “xxxxx.hex” file to an empty USB memory stick.
2. Connect the USB memory stick (with “xxxxx.hex” file already stored) to the USB input (rear panel UPGRADE input for M51). With the unit plugged-in to a mains power source, press and hold the front panel Standby button. While holding down the Standby button, switch ON the rear panel POWER switch.
3. Release the Standby button when “Updating” is displayed on the front panel. The unit will automatically go to standby mode after completion of the update.
also if you want to know what update ver you got
HOW TO CHECK SOFTWARE DETAILS
1 Press and hold front panel INPUT or the Source Right u(C510) button while switching ON the rear panel POWER switch.
2 “SETUP”, “VFD TEST”, “Vx.xx” (software number) and “RESET” will be shown in the display.
