Hi,
I just bought a new TH-7800 from China and what really concerns me is a very loud beeping which I cannot switch off. It starts as soon as I turn the device on, changing channels doesn't help, neither hard resetting does. I tried numerous switch offs and back ons and only in few cases beeping didn't start but after pressing some buttons it again started loud beeping. It stops beeping when I press quickly left volume/sql knob to switch into single receive on. It is according to manual 17 (bottom section). When I switch single receive off it starts beeping loudly with no end
I made a short movie of this symptom: https://youtu.be/7Z4L8t67_iU
Anyone have any idea?
Thx
Igor
