K8098 contrast adjustment problem

Hello all,
Just completed this kit and all was well. Adjusted the contrast just see if I could improve it slightly. Went beyond veiwable and then discovered I could not move it back. Unpluged the power and powered it back up and then discovered that the contrast setting was saved. So now I can’t see anything. Anyone know how to get the contrast lower if I can’t see the screen or how do you reset for original start up settings???
Thanks in advance,
John

We’ve checked but the firmware does not seem to feature a ‘reset’-function.
Anyway, you can try this, we did and it works:

Power up the unit and wait for a couple of seconds.
Press and hold button and count to 5 (enter menu) then release.
Press and hold button while counting to 2 five times in a row.
Short press.
Press and hold button while counting to 2.
Now you should be in the ‘contrast’ menu.
Short presses will adjust the contrast.

If you make a mistake, just restart.

Thank you so very much! The fix was just as easy as messing up on my part.
