All Manuals Search And Download.   CASSETTE TAPES   CASSETTE TAPES   PROTECTING YOUR RECORDINGS   There are many different types of cassette tapes available.   However, they all conform to standard specifications so any   brand may be used with the deck.   All cassette tapes are provided with erasure protection holes   to prevent accidental erasure of recorded contents. There is   a small tab covering the hole on each side of the cassette,   and it should be broken off after recording the tape. Without   this tab covering the hole, it is impossible to record onto that   tape. Thus, you can safely protect a recording for as long as   you wish without fear of accidental erasure. Should you wish   to use a cassette tape protected in this way for recording,   simply covering the hole with adhesive tape will permit   erasure and re-recording.   ÷ Classification of Cassette Tapes by Formulation:   Cassette tapes are available in four basic types depending   on their formulation, or type of magnetic material and   manufacturing process. These four types are commonly   known as Normal (Type I/NORM), Chrome (Type II/HIGH   <CrO2>), Ferrichrome (Type III/FeCr), and Metal (Type IV/   METAL), and they each require specific tape deck   adjustments for optimum performance.   * YAMAHA does not recommend the use of 120 minute   length cassettes since the extreme thinness of the tape   makes them susceptible to mechanical and recording   problems.   ÷ When using Chrome (Type II/HIGH <CrO2>) or Metal   (Type IV/METAL) tapes, make sure you do not cover the   hole intended for the Auto Tape Selector operation.   AUTO TAPE SELECTOR DETECTION SLOTS   The deck has a built-in Auto Tape Selector which   automatically adjusts for the proper bias, level and   equalization according to the tape formulation — all you   have to do is to load a cassette and the Auto Tape Selector   does the rest.   The Auto Tape Selector determines which type of tape is   loaded by sensing detector slots in the top of the tape shell.   Each tape formulation has its own characteristic hole   markings standardized by the tape industry.   ÷ Early model Metal (Type IV/Metal) tape formulation   cassette shells do not have the slots for Auto Tape   Selector operation. As a result, early model Metal type   tapes recorded on another deck will be played back with   the deck at the Chrome (Type II/HIGH <CrO2>) settings.   YAMAHA does not recommend using this kind of tape.   ÷ The deck does not have the required setting for   Ferrichrome (Type III/FeCr) tape, since this tape   formulation is not widely used. Should you use a   Ferrichrome tape, it will be recorded and played back at   the Normal (Type I/NORM) settings, which will result in an   unnatural high frequency emphasis. This effect may be   compensated for somewhat by adjusting the PLAY TRIM   control and/or the tone controls of your amplifier/receiver   during playback.   TAKING UP SLACK IN THE TAPE   As a precaution against tape entanglement and damage,   remove any slack in the tape before inserting cassettes into   the deck. This is accomplished by inserting a pencil, pen or   similar object into one of the spools and gently winding it   until all the slack is removed. You do not have to wind it too   tightly.   Be careful not to touch the tape part itself. It is very delicate   and touching it may damage the tape and its recorded   contents.   TYPE II   TYPE IV   Detector slots   Detector slots   STORING CASSETTES   After putting a cassette tape back into its case, store it in a   location away from exposure to direct sunlight, humidity,   high temperatures, and magnetic fields (away from television   sets, speakers, etc.). High temperatures and humidity will   damage the tape itself, while exposure to magnetic fields   may cause a loss of recorded material. Avoid touching the   tape surface with your fingers, since dirt or finger oil will   contaminate the deck’s heads.   14   Download from Www.Somanuals.com.

At this time you should use a commercially   available cassette tape-type head demagnetizer.   ÷ When cleaning the tape path or demagnetizing the heads,   be sure to follow carefully the instructions of the   concerning materials such as cleaning fluid or head   demagnetizer.   OPTIONAL REMOTE CONTROL TRANSMITTER   With the optional remote control transmitter RKX1, you can   operate this unit at your listening position.
