Safety

1. Power Source—The unit should be connected to power supply only of the type described in the operating instructions or as marked on the unit.
2. Polarization—If the unit is equipped with a polarized AC power plug (a plug having one blade wider than the other), that plug will fit into the AC outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
3. Power Cord Protection—AC power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them. Never take hold of the plug or cord if your hand is wet, and always grasp the plug body when connecting or disconnecting it.
4. Nonuse Periods—When the unit is not used, turn the power off. When left unused for a long period of time, the unit should be unplugged from the household AC outlet.

Installation

Environment

1. Outdoor Antenna Grounding—If an outside antenna is connected to the receiver, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1990, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See figure below.

NEC—NATIONAL ELECTRICAL CODE

Listening caution

Selecting fine audio equipment such as the unit you've just purchased is only the start of your musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your equipment offers. This manufacturer and the Electronic Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion—and, most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing "comfort level" adapts to higher volumes of sound. So what sounds "normal" can actually be loud and harmful to your hearing.

Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

- Start your volume control at a low setting.

- Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.

Once you have established a comfortable sound level:

- Set the dial and leave it there.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.

We Want You Listening For A Lifetime

Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association's Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels* is included for your protection.

•The level used here is different from that displayed on the system's display.

Decibel

Level Example

30 Quiet library, soft whispers

40 Living room, refrigerator, bedroom away from traffic

50 Light traffic, normal conversation, quiet office

60 Air conditioner at 20 feet, sewing machine

70 Vacuum cleaner, hair dryer, noisy restaurant

80 Average city traffic, garbage disposals, alarm clock at two feet.

THE FOLLOWING NOISES CAN BE DANGEROUS UNDER CON- STANT EXPOSURE

90 Subway, motorcycle, truck traffic, lawn mower

100 Garbage truck, chain saw, pneumatic drill

120 Rock band concert in front of speakers, thunderclap

To preset AM broadcast frequencies into the memory:

Select AM in step 2, then follow steps 3 and 4.

To confirm the preset stations:

Note

When you preset a broadcast station to a channel that has already been preset, the previous presetting will be erased. So if, for example, FM frequencies are preset from channel 1 to 39 and then AM frequencies are preset, the first AM frequency will be preset to channel 21 (thus erasing the FM presetting of channel 21), the second AM frequency will be preset to 22 (erasing FM 22), and so on.

About the TUNER/BAND indicator:

While listening to radio broadcasts: Lights in green.

While listening to compact discs or tapes: Lights in orange.

Preset memory contents maintenance:

The contents of the memory will continue to be stored for approximately 2 weeks, even if the power supply cord is disconnected.

Correct presetting may not be possible in cases where the broadcast waves are too strong or too weak. In such cases, carry out presetting manually. (See next page.)

If the reverse side (◀) of the tape is playing:

The reverse operation should take place.

Note

TPS (Tape Program Sensor) is the function that searches for the silent passage in a tape program. So, it may sometimes fail to operate correctly in the following situations:

• When there is no blank space between tape programs (for example, when you are playing a tape recorded from a microphone)
• When the interval between programs (blank space) is less than 4 seconds
• When there is a particular low-level passage or silent passage in the middle of a program (For example, classical music)
• When the program is less than 10 seconds, or when it is less than 10 seconds from the beginning of the program to the beginning of the next program
• When a tape has been recorded with fade-ins (the function that increases the volume level gradually at the beginning of a program) and fade-outs (the function that decreases the volume level gradually at the end of a program)

For your reference:

Each decks' play direction is stored in the system's memory. So the play direction may change when you press DECK 1/2.

To fast forward or rewind the tape

Press ◀◀ (TPS) or (TPS) ▶▶ while the tape is in the stop mode.

If the forward side (▷) of the tape is playing:

If the reverse side (◀) of the tape is playing:

The reverse operation will take place.

On this unit, if there is less tape on the take-up side than on the supply side (refer to the illustration below) at the time that ◀◀ or ▶▶ is pressed, the speed of the rewind/fast-forward operation will automatically be increased for approximately 1.5 times the normal speed. This function makes it possible to wind the tape faster when there is a large amount of tape to be wound.

Notes

• When there is more tape on the take up side than on the supply side, the tape will be wound at the normal speed.
• If high speed winding is begun from a state in which the tape is partly wound, such as that shown in the illustration above (for example, when the ratio of tape between the two sides is 1:3), high speed winding will continue until the ratio between the two sides reaches 3:1, and then the remaining winding will be done at the normal speed.

For your reference:

You can fast forward or rewind the tape while you are playing or recording a tape in another deck. Press DECK 1/2 to switch to the non playing deck, and then press ◀◀ or ▶▶.

About Dolby Noise Reduction system

Using Dolby NR reduces tape hiss in the high-frequency range. It boosts the level of the high-frequency during recording, and lowers it by the same amount during playback, simultaneously reducing high-frequency interference incurred during the recording process.

This system has the Dolby B-type of noise-reduction system. With Dolby B NR, the noise is reduced by 10 dB at high frequencies. If you are playing a tape that was recorded with Dolby NR, use Dolby NR during playback for best results.

Dolby noise reduction manufactured under license from Dolby Laboratories Licensing Corporation.

Press the center holder and lift the disc holding it by the edges.

Illustration showing a hand holding a circular object next to another hand holding a ring (no text or symbols present)

To hold the disc

Hold the disc by the edges so the surface is not soiled with fingerprints. Fingerprints, dirt and scratches can cause skipping and distortion.

To store a disc in its case

Insert the disc with the label facing upwards and press downward at the center.

If the surface is soiled

Wipe gently with a soft, damp (water only) cloth.

If the disc is brought from a cold to a warm environment, moisture may form on the disc

Wipe this moisture off with a soft, dry, lint-free cloth before using the disc.

Improper disc storage:

You can damage discs if you store them in the following places:

●Areas exposed to direct sunlight
●Humid or dusty areas
- Areas directly exposed to a heat outlet or heating appliance

Handling precautions:

• Do not write on the label side with a ball-point pen or other writing utensils.
• Do not use record cleaning sprays, benzene, thinner, static electricity prevention liquids or any other solvent.
• Do not soil with fingerprints.

Maintenance

Maintenance of external surfaces

To clean this unit, use a soft, dry cloth.

If the surfaces are extremely dirty, use a soft cloth dipped in a soap-and-water solution or a weak detergent solution.

Wring the cloth well before wiping the unit.

Wipe once again with a soft, dry cloth.

Never use alcohol, paint thinner, benzene, or chemically treated cloths to clean this unit. Such chemicals may damage the finish of your system.

Tape head care

Do not use any solution other than alcohol for head cleaning.

Concerning cassette tapes

Selection of cassette tapes

You can use normal, chrome, and metal tapes for recording:

• The deck automatically identifies the kind of tape loaded, and sets the bias (for recording) and equalization accordingly.
  ●The deck automatically sets the recording level.

Cassette tapes exceeding 90 minutes:

These tapes are handy for their long playback and recording time but be careful about repeatedly stopping and starting, rewinding and fast forwarding these tapes in short intervals as they are thin, tend to stretch and may become entangled in the deck mechanism.

Do not use the Fe-Cr tapes (TYPE III) in this system:

If you use this tape, it is impossible to obtain the required flat frequency response.

If the tape loosens, take up the slack

Tape slack may cause the tape to break.

To prevent erasure of recorded sounds

Remove the erase-prevention tabs with a screwdriver or a similar object.

To re-record on a protected cassette, cover the slot with adhesive tape.

Do not cover the detection holes on chrome and metal tapes.

Improper tape storage:

You can damage tapes if you store them in the following places:
- In high temperature [35°C (95°F) or higher] or high humidity (80% or higher) areas
- In a strong magnetic field (near a speaker, on top of a TV, etc.) This can erase a recording.
●Areas exposed to direct sunlight
