ayon cd 5s remote controller

hi everyone
I bought a brand new Ayon cd 5s and I really love it with great care.
but suddenly the remote controller does not work.
does anyone has same problem? please give your kind advice.

thank you very much
This might be simplistic - check the batteries.
This thing eats batteries
Mine has worked flawlessly for a year with no battery change. If you just bought it after checking batteries I would ask them to send you a new one
