Hi everyone,

I have a problems with Profilux Plus II.
I can't use profilux using keys on device. Despite the pressing of buttons nothing happens.
I hear only clickin signal ( beep ) when I press buttons.

Other functions of this Profilux works well. I can connect to device by PC app, set everything.
Some times I see blinking Alarm LED only.
on PC app in Remote Control LCD display the same what is on device. There is only http address to GHL.
In remote tab buttons not working too...

When I'm restarting device I see information about detected cards in slots, Intro with eating fish on first line and... that all :-)
When I made firmware update LCD is changed and I see firmware update ... press yes....
So, It looks like LCD and key are OK.

I've made upgrade to firmware 5.15 now.
As you can see there was replaced LCD screen which was damaged but the problem was before.

Now I can't calibrate ph probe for example :-(
