What means TRIPLE-MODE HI-FI on this model? At first glance I think on something similar to Moondrop model, but this has no audio output at first view.
How do I interact with the LCD to change the date or time? I just got mine and the instructions are entirely in Chinese and google translate isn't telling me.
I found this video (https://www.youtube.com/watch?v=cH2feyYD_cc) and you can interact with the screen with the dial. However, there is an odd feature: The dial can be enabled or disabled. Do FN + press dial to enable or disable the dial. You don't get any confirmation of the setting, so press once and then see if the dial does anything. If it doesn't try pressing again.
You can change the display language using the upper right knob fairly easily. Also, the driver is available here where you can change everything in the software: Infiverse INFI75 Driver (epomaker.com)
No, they just use the term to say that the KB sounds good. It's a bit of a misnomer, because it has nothing to do with "fidelity" or sound reproduction.
