델 무선키보드 마우스 km7321w 모델 키보드 자판 무입력 문의 드립니다

I purchased a Dell wireless keyboard mouse model km7321w, but the / and - keys on the right numeric keyboard do not work.

I installed and updated the software, but it still doesn't work.

Sometimes I get frustrated because the Korean/English keys don't work.

If you need it, I have recorded it on video, so please contact me and I will send you the video.

I purchased it from Coupang online on September 23rd and would like a quick response.
