WARNING TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. This unit is not disconnected from the AC power source as long as it is connected to the wall outlet, even if this unit itself is turned off. This state is called the standby mode. In this state, this unit is designed to consume a very small quantity of power. For U.K. customers If the socket outlets in the home are not suitable for the plug supplied with this appliance, it should be cut off and an appropriate 3 pin plug fitted. For details, refer to the instructions described below. Note: The plug severed from the mains lead must be destroyed, as a plug with bared flexible cord is hazardous if engaged in a live socket outlet. IMPORTANT THE WIRES IN MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE: Blue: NEUTRAL Brown: LIVE As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. Making sure that neither core is connected to the earth terminal of the three pin plug.

Set the dubbing speed to either NORMAL (normal speed) or HIGH (twice the normal speed) with the DUBBING buttons*. Dubbing starts automatically. DUBBING A # BNORMAL HIGHThe corresponding NORMor HIGH indicator lights onthe display.

• Higher quality sound will be obtained with the NORMAL setting. Note During dubbing, Dolby NR is automatically set to off and the recorded tape can be dubbed as is. (When the tape to be dubbed is recorded with Dolby NR, this effect is also dubbed.) PLAY TRIM control adjustment (KX-W421 only) For normal use, set the PLAY TRIM control to the center position. When the high frequencies sound is too noticeable or too weak while monitoring the sound of DECK B, compensate the high frequency response with the PLAY TRIM control before dubbing. The compensated sound can be dubbed onto DECK B. As the compensation result depends on the quality of the tape loaded in DECK A, the monitored sound cannot be recorded as it is. Refer to “PLAY TRIM CONTROL ADJUSTMENT” on page

To stop dubbing Press the & button. (If you press the & button on DECK B, both decks stop simultaneously and the dubbing mode is cancelled. If you press the & button on DECK A, DECK A stops immediately and then DECK B stops after recording a 4-second blank section.) When the tape in DECK B reaches its end, DECK B stops and then DECK A stops. When the tape in DECK A reaches its end, DECK A stops and DECK B stops after providing a blank section of about 4 seconds. Available operations while dubbing The Rec Return function can be carried out on DECK B. Refer to “REC RETURN OPERATION” on the previous page. You can make dubbing from DECK A to DECK B. Open the cassette compartments by pressing the EJECT buttons and load a blank cassette tape in DECK B and the original cassette tape in DECK A.

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. ÷ When using Chrome (Type II/HIGH <CrO 2>) or Metal (Type IV/METAL) tapes, make sure you do not cover the hole intended for the Auto Tape Selector operation.

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. 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. CASSETTE TAPES CASSETTE TAPES 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. ÷ 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 <CrO 2>), 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.

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 <CrO 2>) 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. Detector slotsDetector slots

With the optional remote control transmitter RKX1, you can operate this unit at your listening position. For details, refer to the instruction manual supplied with the remote control transmitter.

CLEANING OF THE TAPE PATH

Continued high quality performance of your deck is dependent upon periodic cleaning of the heads, capstan, pinch roller, and all surfaces over which the tape travels. Normal use will cause an accumulation of dirt and dust on the heads, capstans, and pinch rollers. This can lead to poor sound quality, drop outs (intervals with no sound), unsteady tape speed, loss of high frequency response, etc. Thus, clean the heads and all surfaces over which the tape travels with a commercially available cleaning cassette and fluid type cleaner. DEMAGNETIZATION After 20-30 hours of use, enough residual magnetism will build up on the heads to cause poor high frequency reproduction. 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.
