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...

MAINTENANCE
Before carrying out any maintenance operation, always disconnect the plug from the wall socket. Warning This appliance contains hydrocarbons in its cooling unit maintenance and recharging must therefore only be carried out by authorised technicians.
Defrosting
The freezer compartment will become progressively covered with frost. This should be removed with the special plastic scraper provided, whenever the thickness of the frost exceeds 1/4". During this operation it is not necessary to switch off the power supply or to remove the foodstuffs. However, when the ice becomes very thick on the inner liner, complete defrosting should be carried out and it is advisable to carry out this operation when the appliance is empty. To carry out complete defrosting proceed as follows: 1. Remove any stored food, wrap it in several layers of newspaper and put it in a cool place. 2. Turn the thermostat control � to the «q» setting. 3. Leave the door open and insert the plastic scraper in the special location to act as an extension channel; pull out the drawer to collect the defrost water (see Fig.). 4. When defrosting is completed, dry the interior thoroughly. Keep the scraper for future use. Warning Never use metal objects for defrosting your appliance as it may get damaged. Do not use a mechanical device or any artificial means to speed up the thawing process other than those recommended by the manufacturer. A temperature increase of the frozen food shortens its safe storage period.
