I took mine back to the service centre. It turns out the clamp that hold the battery was loose.
This has been tightened along with one only switches that needed some silicone spray into it. The switch itself was loose too and needed tightening. In addition the spring inside the switch was stretched a little.
The clock error is now gone!!!
The final summary is that my unit is functioning properly now!! Yippee!
Hopefully trouble free from herein! a little disappointed in the first two months of ownership. Here’s to a better more reliable future as the Kemper sounds the goods.
