Remote Control of my Dreambox One Combo

Hi,

The remote control of my Dreambox One Combo doesn't respond when I press the buttons. I've tried reinstalling OpenPli 8.0 image, but I can not finish the new configuration because the problem with the remote is still persisting. And when I press some buttons, then the circular button "MODE" at the top center appears lighted in green. What can I do for now?

Thanks in advance

auto-reply : problem solved

After changing batteries , I press the button "MODE" and suddenly the button changes its light from green into blue. Then I can handle the receiver with the remote.

Thanks.
