VP998 noise Reply

 Dear Wellon,

my VP998 has a strange issue, when it is writing or reading from the chip, it makes a very loud, high-pitched noise.
I attach a video, please let me know, if this is a problem, or is it only bad for my ears. I have tried with other external power supply, but the problem stays.
Thank you,
Yours:
Janos

 You also seem to have a problem with your programmer. How do you know, it is not coming from there?
