Troubleshooting and error codes
| Items | Measurement conditions | Measurement method | Standard Values | Adjusting positions |
|---|---|---|---|---|
| Confirmation of head angle | Test tape :TA-182A(8KHz) Measurement output terminal :Speaker terminal Speaker R (Load resistance:3 ) :Headphone terminal |
1 Playback the test tape TCC-182A (8KHz) 2 With the recording & playback mechanism, adjust the head azimuth screw so that the left and right output levers become maximum, After adjustment, lock the head azimuth at least by half turn. |
Maximum output | Adjust the head azimuth screw only when the head has been changed |
| Confirmation of tape speed | Test tape TCC-112(3000Hz) Measurement output terminal :Headphone terminal |
Adjust VR501 so that the frequrncy counter reading becomes 3,010Hz +/-15Hz when playing back the test tape TCC-112 (3000Hz) with playback and recording mechanism after ending forward winding if the taoe. | Tape speed of deck :3,010Hz +/-15Hz |
