hello,
if you want to open this case, you have to screwing out the four gold pillars, and tear up the white tags, and then you can see the four screws, and unscrew them.
so you can open the case.
hope this will help you.
best regards
I recently bought the same device (F900 bt mini amp) via Amazon to connect two passive speakers to my PC. I have connected the Amp to my PC audio Output via the included 3,5 mm stereo cables. Works in general, but since I run the amp I have a strange problem with my VDSL router that is also connected to my pc via lan cable… in 50% of the cases when I switch the little amp on, my VDSL connection is suddenly lost and the router has to resync the DSL signal… this is so annoying, how can that even be possible? Any interferences between the bt signals and the Vdsl signals?
hi,
there are no interferences between the bt singals and the vdsl signals in normal conditions.
we are sorry we don’t know why your VDSL connection is suddenly lost and the router has to resync the DSL signal.because we are not use the vdsl.
hope you can understand.
best regards
