This GRUNDIG UV5A Owner Manual is not only an instruction manual but a total functional circuit description of the Multimeter and includes circuit diagram at the end pages. It is very helpful for repairing and calibrating the instrument. It is written in two languages English and German for international support. It was very easy to repair my unit with this document. Regards, Regis Pauly, Electrical Engineer.
The owner's manual was evetything I thought it would be. I was able to print it out using both sides of the paper in quick order, saving me a search online for a used one.
Was happy to find the complete owners manual... It's all in there, just like the original...

Using and Replacing the Light Bulbs
The Cooktop light
The Top Light Switch is located below the control panel. Push the right side of the switch to turn the light ON. Push the left side of the switch to turn it OFF.
To replace the fluorescent
tube and starter:
2. With both hands, pull top of light
cover towards you and lift it out of bottom support trim.
