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...

How to use the refrigerator
For adequate cooling developing interior air circulation is necessary. For this reason you are asked not to cover the air circulation gaps behind the shelves (e.g. with tray etc.). Do not put hot food into the refrigerator. Allow it to reach room temperature naturally. In this way the unnnecessary frost building up can be avoided. Foods can take over odours from each other. So it is essential to put foods in closed dishes or wrap them in cellophane, aluminium foil, greaseproof paper or cling film before placing them into the refrigerator. This way foods will keep their moisture e.g. vegetables will not dry out after some days.
Display background colour
By default the display background is blue. While whatever button or knob is used the background turns bright blue and remains so for a while. The display background turns red, if the temperature inside the freezer is too warm (alarm). If this is the case, the digits show blinking the warmest temperature inside the freezer, the high temperature symbol flashes and an acoustic alarm signal is shown. The temperature might be too warm in the following cases: Immediately after switching on The freezer door was left open for a longer time There is an operating trouble in the freezer To switch the alarm sound off press the "E" button. The display returns to showing the ambient temperature, however the background remains red until the freezer cools down properly. Should you press no button during alarm, press the "E" button when the sound finishes to see the warmest temperature reached during the alarm.
Using the Appliance
Putting it into use
Place the accessories into the appliance then plug to the mains socket. Press the "A" button. The backlight of the display turns on. The applince is ready to use. Pressing the "A" button again the appliance is off, but still under voltage.
Controlling the temperature, setting
The thermostats interrupt the cooling automatically for more or less time depending on the setting then restarts it assuring the required temperature. Temperature of the refrigerator and freezer can be set by knobs "F" and "B", respectively. The set temperature is seen blinking on the display. For everyday use medium setting, i.e. +5°C in the refrigerator and colder than -18°C is the freezer is recommended. Allow the appliance to run for a period of 24 hours whenever the temperature setting is changed. This will allow the temperature to stabilise inside the appliance. The temperature coming about in the refrigerator is effected by not only the position of the thermostat but the ambient temperature, frequency of door openings and the quantity of food put into it newly, etc. When the coldest temperature possible is set - in case of increased demand e.g. during heatwaves - the compressor may operate continually. This does not cause damages to the appliance.
