 ;
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.
3-11. Upgrading the FPGA Program Version
3-11. Upgrading the FPGA Program Version
The DSR-1800/P/1600/P mounts the FPGA (field programmable gate alley) on the process board and uses flash ROMs for loading this program. The version of these flash ROMs mounted on the board can be upgraded using the following method.
3-11-1. Upgrading the Version
(1) Prepare a DJ-499 (J-6444-990-A). (2) Write the required number of rewrittable program files in the PROM (M27C1001-70F1 (F8) (8-75958-91) or equivalent). Refer to the following for the number required. (3) Mount the PROMs in order from the one with the smallest number to the DJ-499 IC100 to IC103. (4) Set the DJ-499 as follows. (5) With the power of the unit set to OFF, mount the connector of the corresponding board to DJ-499. (6) Turn ON the power of the unit. . Of the three LEDs on the DJ-499, the green D1 at the end lights up and goes off. (The dummy data will be loaded in the FPGA. It will be completed when D1 goes off.) . The same green D1 will blink after a while. (The flash ROM on the board is erased and new data is downloaded.) . It stops blinking, and the green D2 in the middle lights up, meaning that upgrading has ended normally. . If the red D3 in the middle lights up halfway through, it means that a writing error has occurred. Check if the DJ-499 is connected properly, and perform from step (6).
