When you provide power to the ARGON8M synthesiser and power on using the power switch, you should see LEDs light up and a boot-up page with the name of the synthesiser appear on-screen.
If this isn't the case, first please check that you are using the correct power supply. We recommend that you only use the power supply provided with the synth, however if this is no longer available to you then you will need to use a power supply with the following specification - DC, 9.0V, 1.5A centre-positive.
The synth cannot be powered via the USB port.
