User manual SONY TC-M77V

[. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ­ Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. ­ Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. [. . . ] However, we recommend that you repeat the automatic calibration procedure each time you insert a new cassette since cassettes of the same type also vary in their characteristics. Before recalibrating, be sure to turn off "[A] CAL" or "CAL [B]" by pressing DECK A or DECK B. Then start from Step 2 of the automatic calibration procedure. The Auto Rec Level function automatically measures the peak signal level and adjusts the recording level accordingly. The Auto Rec Level function operates during normal recording, Relay Recording or Simultaneous Recording on either deck. You should adjust the recording level manually with REC LEVEL in the following cases: --The recording level cannot be adjusted properly due to excessive noise in the program source. --The program source level is too low and the recording level does not increase. During a quiet passage in a program source such as classical music, the recording level may not increase for some time. If a high sound level is expected later on in the track, play that portion first so that the right adjustment can be obtained. --The recording level does not decrease for a long time. The Auto Rec Level function may not work properly when you try to record sound produced by a graphic equalizer that has extremely high-level signals. Adjust the recording level manually, if necessary (see page 7). If a TV set is placed near the tape deck, noise may occur during high-speed dubbing. In that case, turn the television set off or move it away from the tape deck. You can do this only during the normal-speed dubbing. Locate the point you want to resume recording on deck A, then stop the tape. On deck B once; otherwise, Relay Recording stops when the reverse side of the cassette in deck B finishes. You can record the same source on cassettes in deck A and B at the same time. You can record an RMS program that you've created (see "Creating Your Own Program (RMS Play)" on page 9). This function works only at normal speed. Make sure that record-protect tabs on the cassettes have not been removed. Insert the recorded cassette into deck A and a blank cassette into deck B. [. . . ] / This noise is caused by the cassette and is not a mechanical problem. Move the tape deck away from the TV or VCR. / The tape deck is placed on or under the amplifier. Move the tape deck away from the amplifier. [. . . ]
