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.

Perfect like it was descriped, Perfect like it was descriped

Very good detail, all pages clear, exactly what I needed
AH-X08BE/10BE/13BE AY-X08BE/10BE/13BE AY-X08BE-C/10BE-C AU-X08BE/10BE/13BE AE-X08BE/10BE/13BE AE-X08BE-C/10BE-C
(5) Control for prevention of indoor heat exchanger freezing If the temperature of the indoor heat exchanger goes below approximately 5°C during cooling(only Full power operation), the operating frequency is lowered by approximately 5 Hz. After that, the frequency is lowered by approximately 5 Hz once every 60 seconds. When the temperature of the indoor heat exchanger rises above approximately 5°C, the frequency is raised by approximately 5 Hz once every 60 seconds, and normal operation is restored. If the temperature of the indoor heat exchanger goes down to approximately 0°C and this condition continues for 4 minutes, the compressor is stopped. When the temperature rises above approximately 2�C, normal operation is restored. 2-3 Overcurrent protection (1) Compressor lock detection If the set value (AE-X08BE/X10BE/X13BE: 2.7A,AE-X08BE-C/X10BE-C: 2.7A, AU-X08BE/X10BE/X13BE: 2.7A) of AC current is exceeded in 6 seconds when operation begins, operation is stopped. In this case, the compressor outdoor fan does not stop, and 170 seconds after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. (2) DC overcurrent detection, AC overcurrent detection To protect against overcurrent due to sudden changes in load, the compressor is stopped if the set value (AEX08BE/X10BE. AE-X08BE-C/X10BE-C. AU-X08BE/10BE: 26A, AE-X13BE. AU-X13BE: 47A) DC is exceeded in the DC section, or the set value (AE-X08/10BE. AE-X08-C/10BE-C. AU-X08/10BE: 11A, AE-X13BE. AU-X13BE: 13A) AC is exceeded in the AC section. In this case, the outdoor fan does not stop, and 170 seconds after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. 2-4 Compressor protector control If the temperature of the compressor chamber exceeds 114°C, the compressor is stopped. In this case, the outdoor fan does not stop, and when the compressor chamber temperature decreases to 100°C three minutes after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. 2-5 Power transistor module protector If the temperature of the chips in the power transistor module exceeds 105 °C, the compressor is stopped. In this case, the outdoor fan does not stop, and when the temperature of the chips in the power transistor module decreases to 105 °C 170 seconds seconds after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. 2-6 Power factor module (AE-X08BE/X08BE-C, AE-X10BE/X10BE-C, AU-X08BE, AU-X10BE) If a voltage error (over 400 V), current error (over 17 A), or temperature error (over 90°C) is detected in the power factor module, 170 seconds the compressor is stopped. (AE-X13BE, AU-X13BE) If a voltage error (over 420V) is detected at power factor module output voltage, 170seconds the compressor is stopped. In this case, the outdoor fan does not stop, and 170 seconds after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. 2-7 Serial signals (1) Serial signals consist of all 96-bit signals. (2) If the outdoor unit does not receive a serial signal, it will stop approximately 30 seconds later. Note that this is true only of normal operation; in test mode, it does not stop and operation takes place based on the test mode commands.
