[. . . ] Be sure to make connections firmly to avoid hum and noise. To play a tape recorded with the Dolby NR* system turn DOLBY NR to the same Dolby system that the tape was recorded in--B , C , or S . Please note that the B, C, and S settings on both sides are identical during playback since the MPX filter operates only during recording. With the side you want to play facing you Do not press POWER or § while the tape deck is operating. [. . . ] However, we recommend that you repeat the automatic calibraion procedure each time you insert a new cassette since cassettes of the same type also vary in their characteristics. Before recalibrating, be sure to clear the existing calibration data by pressing AUTO CAL until "AUTO CAL" disappears from the display. Then start from Step 2 of the automatic calibration procedure. 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. You can insert a blank space of 4 seconds between each track. The blank spaces between tracks let you locate the track easily with the Multi-AMS function (see page 8). Also, use this function to eliminate only unwanted portions on the tape. Do not disassemble the cabinet -- this may result in an electrical shock. Should any solid object or liquid fall into the cabinet, unplug the tape deck and have it checked by qualified personnel before operating it any further. Before operating the tape deck, check that the operating voltage of the tape deck is identical with your local power supply. If you are not going to use the tape deck for a long time, be sure to disconnect the tape deck from the wall outlet. To disconnect the AC power cord (mains lead), grasp the plug itself; never pull the cord. AC power cord must be changed only at the qualified service shop. The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off. Press R REC MUTE once when you want to insert a blank space. "REC" in the display starts flashing and the tape moves on without recording any signals. After 4 seconds, "P" lights up and the tape deck is now ready to resume recording. To insert a blank space longer than 4 seconds Hold down R REC MUTE as long as you want. After 4 seconds, "REC" in the display flashes faster. When you release the R REC MUTE , "P" lights up and the tape deck is ready to resume recording. Because of a safety mechanism, the function buttons will not operate if the cassette holder is not completely closed, if there is no cassette in the cassette holder, or if a cassette has been incorrectly inserted into the cassette holder. [. . . ] The Dolby NR system boosts the low-level signals in high frequency during recording and restores them during playback. there are 4 types in the Dolby NR system: A , B , C and S. A-type is for professional use (not available on this tape deck), and B, C and S-types are for consumer use. S-type has the maximum noise reduction capability, followed by C and B. [. . . ]
