A complete and well done copy of the manual, at a not expansive price!
The delivery of the manual is very fast.
Thank you for all

Perfect quality. Was able to fix speed drifting on my Sansui Turntable using the service manual instructions for PLL adjustment.

I am very happy regarding the online purchase of this manual from Owner-Manuals.com as with this I could set right my Denon CD player and Amplifier.
I once again sincerely thank them for the prompt service which was rendered to me.

More than pleased with my prurchase, very good product for the price.

Manual-link came 30 minutes after having paid for an extremely rare (40 years old) item (sony icr-120) and helped me to get the radio rework again. So really good help for me, fast and reliable delivery and -taken that into consideration- a very reasonable price for that service. So thanks again! Mike, Germany
ICF-CD73/CD73V
Ver. 1.1
SECTION 1 SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S701. (push switch type) The following checking method for the laser diode is operable. � Method Emission of the laser diode is visually checked. 1. Open the lid. 2. Push the S551 as shown in Fig.1. 3. Press the [CD NX] button. 4. Check the object lens for confirming normal emission of the laser diode. If not emitting, there is a trouble in the automatic power control circuit or the optical pick-up. In this operation, the object lens will move up and down 2 times along with inward motion for the focus search.
