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...

Defrosting the freezer
A certain amount of frost will always form on the freezer shelves and around the top compartment. Defrost the freezer when the frost layer reaches a thickness of about 3-5 mm. Remove the freezer drawers and place them on top of each other by turning every other drawer one half turn. Put insulating material around the drawers, e.g. blankets or newspapers. The frozen products can also be packed closely together and be kept in a cold location, e.g. in the fridge. Defrosting can be accelerated by placing bowls with hot water (not boiling) inside the freezer. Take out the drain spout and place it in the bottom freezer drawer where water can collect. Loosen the ventilation grille to enable the bowl to fit under the drain spout. Carefully scrape off the ice when it starts to thaw. Use a wood or plastic scraper. Do not use sharp objects as these may damage the interior. When all the ice has melted, clean and wipe the cabinet dry, then push the drain spout back in place. Switch on the cabinet and replace the frozen foodstuff. Never use a hair drier or other heating appliances to speed up defrosting. Excessive heat may damage the plastic interior, and humidity could enter the electric appliance making it live.
To Change the Light Bulb
The light is switched on automatically when the door is opened. Before replacing the light bulb, disconnect the power plug from the outlet. Cut the packaging around the bulb socket. Keep the packaging on to hold the bulb when setting it into the socket. Do not touch the bulb with your bare fingers. Halogen light bulbs are sensitive to grease from the skin. Use a clear halogen light bulb.
When the appliance is not in use
Disconnect the appliance from electricity supply. Empty all foods and clean the appliance, leaving the doors ajar to prevent unpleasant smells. If the cabinet will be kept on, ask somebody to check it once in a while to prevent the food inside from spoiling in case of a power failure.
