how to change DVB-C QAM KIII Pro

Dear all.

I'm new mem, i was received the KIII Pro, but when i scan DVB-C, it don't have any program.

With my DVB-C cable on my TV or STB i just input fre: 730000khz, 6956 kbps, QAM 64, it will have full program.

In setting general in my KIII, DVB-C have region Brazil, China.

I was ordered in tmall.

With DVB-T2 i scan full program, DVB-S2 ok.

Can i use other DTV apps to have change QAM or NIT scan to have full DVB-C program.

Thanks

So bad, the DVB-C Tuner so not sensitive, with my TV and STB Provider Quality is 80%-90%.

Now with booster it can have some program, but it can detect NIT to have full program, i must manual input all freq.
