Code 50, Firmware was up to date.
I used the amp while practicing for an hour or so with no issues other than Bluetooth connectivity.
However, when I used the amp at band rehearsal, the volume fluctuated and diminished to where I could not thear the amp at all.
It might be worth trying a factory reset.
Performing a factory reset will return CODE’s Presets back to when it was new.
To perform a factory reset:
Power OFF the amplifier using the ON/OFF switch
Whilst holding down the AMP Section Switch, turn the power ON.
The screen will display a notification that the amplifier is about to be returned to its factory settings.
If you are sure that you want to perform a factory reset, press and hold the EXIT/STORE switch to confirm.
