[. . . ] REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. Important Safety Instructions 1. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] · On each pair of input or output jacks, the lower jack (marked R) corresponds to the right channel, and the upper jack (marked L) to the left channel. Refer to the amplifier's instruction manual for further information on connections. To AC outlet Plug the AC power cord into a wall outlet. IN (REC) OUT (PLAY) REMOTE CONTROL L L R R L RL R (REC)(PLAY) Connecting to an amplifier Connect the tape deck LINE IN jacks to the TAPE REC jacks on the rear panel of the amplifier and the tape deck LINE OUT jacks to the amplifier TAPE PLAY jacks. Set the Dolby NR by pressing the DOLBY NR button repeatedly until the proper Dolby NR indicator (OFF, B or C) turns on. · Select the same noise reduction system that was used when the cassette was recorded. For instance, tapes recorded using Dolby B NR should be played back with Dolby B NR. Set the Reverse Mode by pressing the REVERSE MODE button repeatedly until the desired mode is displayed. ( b ) repeat: Both sides of the tape are played back repeatedly eight times or until the e button is pressed. · Press the a or s button depending on which side of the cassette you wish to listen to. · The auto-stop mechanism will automatically stop the tape (depending on the tape transport mode) if a tape is played through to the end. Stopping playback Press the e button. 6 TA-R200_En. book Page 7 Tuesday, April 19, 2005 4:36 PM To play a tape Recheck the tape direction settings (shown by the Deck A and Deck B direction indicators) before pressing the d or f button. The following explanation assumes that the tape direction is forward ( s ). A A Fast forward and rewind To fast forward the tape, press the f button. · To stop either fast forward or rewind, press the e button. Automatic tape selection system A A This deck automatically detects the type of cassette in the cassette holder and sets the bias and equalization to the correct settings. Press the s button on this unit and begin playing the source component. You can also use the CD Synchro Recording function if this unit is properly connected to an Onkyo CD player bearing the z symbol. Stopping recording DUBB. STOP t Press the e button. Interrupting recording briefly Press the t button. Making good sound recordings Dolby Noise Reduction System Dolby B NR is the system used in most cassette tape decks to reduce the background noise that is inherent in all cassette tapes. Dolby Laboratories then developed an even more effective noise reduction system, Dolby C NR, in response to the demand for increasingly better sound quality from cassette tapes. Both Dolby noise reductions systems operate by boosting signals during recording that fall below a certain input level. Dolby B and C NR operate on the higher portions of the frequency spectrum using what is called a "sliding band" technique. This is because tape hiss is most prominent during the quiet, high frequency portions of a recording. These same signals are then reduced back to their original strength during playback, thereby reducing the background noise by the same amount. In order to operate only when necessary, the Dolby NR system has a varying effect depending on the input level and frequency of the material being recorded. Dolby C NR is capable of reducing tape hiss by 10 dB more than Dolby B NR. In addition to its noise reducing function, Dolby C NR has an anti-saturation network that lowers high input levels before recording them and returns the signals to their original strength during playback. This raises the high-frequency saturation level of cassette tapes to allow you to record signals that would normally cause distortion. [. . . ] · Do not put thick paper or cardboard labels in the cassette holder. · Do not put tapes near magnetic sources (speakers, amplifiers, TVs, etc. ) Your important recording might be erased or damaged. · Do not expose cassettes to direct sunlight.
