This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. [. . . ] Distortion and noise in the high-frequency response are reduced to produce high-quality sound that can be enjoyed even during playback on other tape decks. After pressing z REC in Step 4 on page 10, turn REC LEVEL so that the peak level meters reach the recommended level for the corresponding tape type. After completing the adjustments, stop playing the program source, then continue the procedure from Step 5. Since there are many different types of cassettes on the market, your tape deck automatically sets the appropriate equalization characteristics and bias current for each tape type (ATS: Automatic Tape Selection). However, you can get better recording results by doing the automatic bias current and the recording level calibration. Even after adjusting the recording level, distortion may occur depending on the source that you're recording from. If this happens, turn REC LEVEL counterclockwise to lower the level. 1 Load the cassette you want to record Make sure the record-protect tabs on the cassette have not been removed. During the calibration, the counter changes from 9 to 0. When the automatic calibration procedure ends, the tape rewinds to the original position, the counter returns to normal and the tape deck stops. The Auto Rec Level function automatically measures the peak signal level and adjusts the recording level accordingly. during fade-in , the AUTO indicator flashes. When the fade-in has completed, the AUTO indicator lights up if the Auto Rec Level function is working, or goes off if the Auto Rec Level function is not working. While you're still recording, press FADER at the point where you want the fade-out to start. Fade-in or fade-out is not possible when REC LEVEL is manually set to 0 (minimum) (see page 11). You can copy a tape in deck A to a tape in deck B at normal or high speed. Make sure the record-protect tabs on the cassette in deck B have not been removed. Recording on the reverse side on deck B starts simultaneously with playback of the reverse side on deck A. During high-speed dubbing, only x is operative. ⷠDubbing is automatically performed with the same recording level and Dolby NR as the original in deck A. You don`t have to adjust the recording level or select the Dolby NR during dubbing. If, however, you want to monitor the sound during normal-speed dubbing, set the DOLBY NR selector to match the tape in deck A (see page 7). [. . . ] ⷠDo not place the tape deck: ­ on a soft surface such as a rug that might block the ventilation holes on the bottom. Cleaning the heads and tape path Heads, the pinch rollers and the capstans with a cotton swab slightly moistened with alcohol or a commercially available cleaning fluid for tape decks. Erasing head Recording/playback head After 20 to 30 hours of use, or when you notice a hissing sound or loss of high frequencies, demagnetize the heads with a commercially available demagnetizer for tape decks. Clean the heads and tape path of the tape deck after every 10 hours of operation to guard against: · Impairment of recording function To ensure better recording, we recommend that you clean the heads and tape path before every recording.
