 ;
very good quality readable manual,printed off very well.
;
The manual was very accurate for the part that I was changing, I was able to order the correct part and had no issues with the replacement procedure. However, I was expecting to have more detailed repairs for the lower drive unit.
 ;
I needed the manual immediately and I got it immediately. I couldn't find this manual anywhere else on the net. The site was easy to traverse, and the price was very reasonable. I'll definitely be back for any future needs.
;
I received a good service manual, with good resolution. Improve the instructions for the purchase because they are not well understood.
For the rest, so good.
Thanks Angel.

Very good documentation for the Grundig 2077 model (as well as similar 800/900/1000 series radios). The first two pages are a summary of reception specifications and output capability. The third page is the tuner dial indicator and dial cord routing diagram. the final ~5 pages are the schematics for the various models (including 2077). The scan quality of the schematics are good, adn can be easily read if zoomed in. The documents are in German, not English as stated. It would have been nice to have the tuning sequence and settings, and some trouble shooting materials... or component and wiring map.

� Installation
(1) Connect the piping between the indoor and outdoor unit firmly. � Incorrect connection may cause the leakage and incomplete vacuuming. (2) Attach the charging hose (manifold gage) to the service port. � Charging hose is necessary to check the pressure and to inject R22 for leakage test. � The valve of charging hose must be closed before being connected. (3) Inject the 100~300g R22 through the charging hose opening the valve. (4) Check the joint part using a gas detector or soapy water for leakage. � On checking, the service valve of main service port must be closed, this test is only for checking whether pipe connection is ok or not. (5) If there is no leakage, discharge R22 in piping completely into tank for retrieving. � Complete discharge is needed for vacuuming. � If leakage is found, please fasten the joint more tightly. (6) After closing the valve of charging hose, disconnect the tank and connect the vacuum pump to charging hose and open the valve again for vacuuming. (7) Turn on the vacuum pump until the pressure drops below 0kg/cm2. (8) After vacuuming, disconnect the vacuum pump and open the spindle of service port (liquid-side) slightly for 30 sec and then open the spindle of (gas side) with hexagonal wrench. (9) Open the liquid side completely first and then the gas side fully in order.
