You can try to see if its Firmware related. If a newer firmware doesn't do the trick, then if that does work, Recommend consulting with the provider to maybe getting the CP changed.
Hello,
The control panel on our 5550N is extremely dim. In the menu under "Control Panel Brightness", the level of brightness seems to be stuck at "1". Using the Up/Down keys does not change the level at all, even though the number scale moves up and down.
Any suggestions that I might try? Other than change the entire CP assembly?
Thanks in advance for your help.
Cheers !
Mike K.
