The manual was of good quality with high resolution schematic diagrams.
;
The manual was very clear and contained all the information I was looking for. My dishwasher is working again because of this servicemanual!
;
Quality scan, great manual. I solved my problem with this manual.

The AKAI 1720 model reel to reel tape recorder described in this Manual is quite an old unit - circa late 1960's. As a consequence, the description of the mechanical details - and adjustments thereof - is quite critical. The manual does this quite well. The schematics are also well presented and have detailed PCB overlays. Probably the only negative is that some half-tone detail has been lost from the original manual as it has been scanned in simple B&W.

7.1.2 Self-Diagnosis Mode
Procedure
1) Open the bonnet and short the Boot Pin (K6003) and GND. (The Boot Pin terminal is located at the upper side of CN6001 as seen from the front.) 2) Turn ON the power. Push "SELECT" key. The self-diagnosis mode is set. LED �0 to 38� on the IRD front panel light up one by one and then all lit. If a LED stops between �0 and 38�, the circuit block corresponding to that number should be checked. 3) When all the LEDs are lit, it indicates that the IRD is waiting for downloading of the Test software "Ggs1001.exe". The Test software "Ggs1001.exe" will be downloaded from the PCMCIA CARD JIG (GGF1377) connected to the IRD. 4) When the downloading completes normally, OK is displayed on the PC display. If OK, it indicates that the Download JIG is operating normally. 5) After completing the downloading, resetting the power supply, and this time all LEDs �0 to 38� will light up one by one, and finally all lit. If a LED stops, the circuit block corresponding to that number should be checked.
Example Downloading of Self-Diagnosis Program
1) Move the cursor to �No.8 PCMCIA ON� at MAKE CHECK_STEP, press the RETURN key ,then move the cursor to "No.25 PCMCIA Download" also at MAKE CHECK_STEP , press the RETURN key and then press the F10 key to end the setting. When the IRD side sets into the downloading standby state, select IRD CHECK from the main menu, and press the RETURN key. Then the IRD CHECK screen is displayed. Press the RETURN key again ,then supply the power to the JIG and "OK" is displayed if there is no problem. Press the RETURN key once more to download the program. Note : If the PCMCIA CARD JIG is not inserted or the CARD JIG part is something wrong ,"NG" is displayed.
