Suggestions for Safety
■Use a standard AC wall outlet
- Use from an AC power source of high voltage, such as for an air conditioner, is very dangerous. There is the possibility that a fire might be caused by making such a connection.
- A DC power source cannot be used. Be sure to check the power source carefully, especially on a ship or other place where DC is used.
■ Grasp the plug when disconnecting the power supply cord
- Wet hands are dangerous.
A dangerous electric shock may result if the plug is touched by wet hands. - Never place heavy items on top of the power supply cord, and never force it to bend sharply.
■AC outlet on rear panel (not equipped for some countries)
- Any equipment connected here should have the specified power consumption or less.
This outlet is exclusively for the connection of other audio equipment, such as a tape deck. Be sure the power consumption does not exceed the wattage specified near the AC outlet. - Never connect other electrical appliances, such as an iron or toaster.
If appliances with a large power consumption are connected, an accident might occur as a result of overheating.
Place the unit where it will be well ventilated Place this unit at least 10 cm (4") away from wall surfaces, etc. Be careful that curtains and similar materials do not obstruct the ventilation holes.
■ Avoid places such as the following: in direct sunlight or in other places where the temperature is high.
In places where there is excessive vibration or humidity. Such conditions might damage the cabinet and/or other component parts and thereby shorten the unit's service life.
■ Be sure to place the unit on a flat, level surface.
If the surface is inclined, a malfunction may result.
■ Never attempt to repair or reconstruct this unit
A serious electric shock might occur if this unit is repaired, disassembled or reconstructed by unauthorized persons, or if the internal parts are accidentally touched.
■Take particular care if children are present
Never permit children to put anything, especially metal, inside this unit. A serious electric shock or malfunction could occur if articles such as coins, needles, screwdrivers, etc. are inserted through the ventilation holes, etc. of this unit.
■ If water is spilled on the unit
Be extremely careful if water is spilled on the unit, because a fire or serious electric shock might occur. Immediately disconnect the power cord plug, and consult with your dealer.
■ Avoid spray-type insecticides
Insecticides might cause cracks or "cloudiness" in the cabinet and plastic parts of this unit. The gas used in such sprays might, moreover, be ignited suddenly.
■ Never use alcohol or paint thinner
These and similar chemicals should never be used, because they might cause flaking or cloudiness of the cabinet finish.
■ Disconnect the power supply cord if the unit will not be used for a long time
If the unit is left for a long time with the power ON, this will not only shorten its useful operation life, but may also cause other troubles.
■ If trouble occurs
If, during operation, the sound is interrupted or indicators no longer illuminate, or if abnormal odor or smoke is detected, immediately disconnect the power cord plug, and contact your dealer or an Authorized Service Center.

Listening to Radio Broadcasts
When broadcast frequencies have been preset to the memory, any of those broadcast frequencies can thereafter be easily selected by simply pressing one of the preset-channel buttons. There are two methods for presetting broadcast frequencies in the memory: the automatic method (see below) and the manual method (refer to page 19); select whichever method you prefer.
Automatic memory presetting

When this method is used, the frequencies of the selected broadcast stations are automatically preset (in sequence to higher frequencies) into the memory: "channels" 1 to 28 are available for the presetting of FM stations, "channels" 21 to 28 are available for MW stations, and "channels" 27 to 28 are available for LW stations. When a presetting is made to a channel that has already been preset, the prior presetting will be erased.
- Press the desired band selector.
FM: for FM broadcasts
MW: for MW broadcasts
LW: for LW broadcasts
Before presetting broadcast stations, press to select the appropriate frequency step for your locality.
(Refer to item 2 on page 10.)
2 Set to the frequency from which you want to start automatic memory presetting.
(Refer to "Frequency tuning", below.)
3 Press and hold the memory button; release it when the display frequency begins to change.
(The memory indicator will flash, and the automatic memory presetting is activated.)
4 Confirm the stations which are preset to each channel, and write them in the station log (page 20).
• To confirm the preset contents by tuning control
1. Set the tuning-mode selector to the "PRESET" position.
2. Turn the tuning control to the left or right to verify the broadcast station.
Notes
- For automatic presetting in areas where there are fewer than 28 FM stations, the remaining channels (through channel 28) will be left unoccupied. The unoccupied channels can be filled by using manual memory presettings.
- For AM broadcasts with extremely strong signal transmissions, the frequency memorized may be slightly different than the correct frequency. If this occurs, make a manual presetting.
Frequency tuning
DOWN: Turn to the left to lower the frequency
UP: Turn to the right to increase the frequency.
- Set the tuning-mode selector to the "AUTO" position.
-
Turn the tuning control to the left or the right until the frequency changes.
-
When the displayed frequency approaches the desired frequency, press the tuning-mode selector to select the "MANUAL" position. (The displayed frequency will stop changing.)
Note:
The changing of the displayed frequency will be automatically stopped (by the automatic tuning function) if a broadcast station frequency is located during the tuning process. If the frequency at which it stops is not close to the desired frequency, repeat step 2 at the left.
4. After stopping at step 3, turn the tuning control so as to tune to the desired frequency.
Note:
If a new broadcast station is preset into a channel, the broadcast station which was previously entered in that channel will be automatically erased.
Manual memory presetting

Stations can be freely preset to any desired channel.
A maximum of 28 broadcast stations can be memorized.
1 Press the desired band selector. FM: for FM broadcasts
MW: for MW broadcasts
LW: for LW broadcasts
Before presetting broadcast stations, press to select the appropriate frequency step for your locality

2 Select the desired broadcast station by using the tuning control and the tuning-mode selector.
(Refer to "Frequency tuning", at the bottom of page 18.)
If noise is excessive in FM broadcasts FM MODE:
Press the FM mode selector.
The sound will then be heard as monaural sound and the FM stereo indicator will not illuminate; the "MONO" FM mode indicator will then illuminate instead of the "AUTO" indicator. If the broadcast signal is weak, sounds can be heard more clearly (than in the stereo mode) by pressing the FM mode selector.
■ Back-up memory
The back-up function maintains the preset memory and the most recent memory (see below) when the unit is switched OFF, in the event of a power failure, or if the power cord is disconnected. The memory will be maintained for as long as approximately one week.
Most-recent memory
The most-recent memory system "remembers" the broadcast station last tuned to when the unit was switched OFF. That station will be automatically tuned in when the power is switched ON.
■ If frequency presettings are accidentally erased
Make the frequency presettings (on page 18 or 19) once again. The power cord should remain connected for one hour or more for the memory back-up to be effective.

About the Dolby noise-reduction recording/playback system
The Dolby noise-reduction system is a system designed to effectively reduce the annoying high-frequency "hissing" noise typically heard from tapes if this system is not used. During recording, the system functions to increase the level of the high-frequency part of the sound, and then, during playback, that same portion is weakened and returned to the previous level. This unit includes two types of Dolby noise-reduction systems, the Dolby B NR-type and C NR-type, as well as the Dolby HX PRO headroom extension system
■ Dolby B-type noise-reduction system
Noise is reduced to about one-third.
Use this system when playing back tapes recorded by the Dolby B noise-reduction system, such as prerecorded music tapes, etc
■ Dolby C-type noise-reduction system
Noise is reduced to about one-tenth.
Use this system for the recording and playback of sound sources that have a wide dynamic range and good tone quality, such as FM broadcasts of live performances, etc., and for playing back such tapes.
■ Dolby HX PRO headroom extension system
By functioning to improve the maximum output level of the tape's high-frequency range, this system permits recordings to be made without a drop of the level of the sound source's high-frequency range. In addition, by using the system in parallel with this unit's noise-reduction system, recording and playback with a greatly extended dynamic range is possible.
Dolby noise reduction and HX Pro headroom extension manufactured under license from Dolby Laboratories Licensing Corporation. HX Pro originated by Bang & Olufsen.

Quick-reverse function
This is a function by which the unit detects the leader tape (the transparent tape at both ends of the magnetic tape) and then automatically reverses (in about one second) the direction of the tape during playback (or recording).

- In order to avoid an operational error, this function is not first effective until about 15 seconds after playback (or recording) first starts.
- This function does not operate for tapes that do not have leader tapes.
- This function may not function correctly: If the leader tapes are colored.
If there is dirt or dust on the tape.
If the magnetic part of the tape is thin
If a strong light (direct sunlight, a spotlight, etc) is shining into the cassette holder.
When the unit is subjected to a strong impact - When the quick-reverse function is not activated, the tape's direction of movement will reverse when the tape reaches its end.
Automatic-tape-select function
This unit is equipped with the automatic-tape-select feature; it automatically detects the type of tape being used, and then makes the suitable adjustments of the bias for recording and equalization accordingly.

About Cassette Tapes
Avoid the following types of tapes
- 120-minute (or longer) tapes
Because this tape is very thin, it might stretch during use, become tangled with rotating parts in this unit, and/or tape movement might not be stable.
- Fe-Cr tape (TYPE Ⅲ)
The high range will be emphasized and a flat frequency response characteristic cannot be obtained.
- Metal tape without detection holes in the cassette
Recordings will be very distorted. (There is no playback problem, however.)

Notes about the handling of cassettes
If the tape in the cassette is loose, the tape can easily break during use or otherwise be damaged.
Never touch the tape itself, or attempt to pull it out of the cassette.
Use a pencil or similar object to take up the slack.

In order to maintain good sound quality during recording and playback, it is recommended that the heads should be demagnetized if distortion or poor sound quality persist after cleaning the heads.
If the heads become magnetized, they could create noise in recordings, loss of high-frequency response, or erasure of valuable recordings. Several types of head demagnetizers are available and may be purchased at local electronics supply stores. Follow the instructions that are supplied with the device.
- Do not bring any type of metal objects or tools such as magnetic screwdrivers in contact with the head assembly.
Maintenance of external surfaces
To clean this unit, use a soft, dry cloth.
For very dirty surfaces, dip a soft cloth in a weak soap-and-water solution and wring well. After cleaning, wipe with a soft, dry cloth. Never use alcohol, paint thinner, benzine, or a chemically treated cloth to clean this unit.
Such chemicals may damage the unit's finish

| When listening to stereo sound, the sound lacks depth (i.e. thin bass, tinny sound). | One of the speakers is connected out of phase [(+) (-), (-) (+)] . | · Reconnect the speakers, maintaining proper polarity [i.e., (+) (+), (-) (-) ]. |
| When listening to stereo sound, the left and right sounds are reversed. | The left and right speaker connections, source connections, or stereo sound processor connections are reversed. | · Check all connections and correct them if necessary. |
| A low-pitched noise (“hum” or “buzz”) is heard. | The power cord or a fluorescent light, etc., is near the connection wires. | · Try separating this unit as far as possible from the electric appliance. |
| Sound is not heard from one of the speaker systems. | The speaker wires are disconnected. | · Check and correct the connections of the speaker wires. |
| The balance control is set too far to one side. | · Set so that sounds are heard at the center, between the speaker systems. | |
| Sound stops during a performance, or no sound is heard when the power is switched ON. | The protection circuitry has functioned because the positive and negative speaker connection wires are “shorted” or speaker systems with an impedance less than the indicated rated impedance of the amplifier are used. | · Switch OFF the power, and, after determining and correcting the cause, switch ON the power once again.· Use speaker systems of the proper impedance rating. |
| While using the tape deck | ||
| Tape moves but no sound is heard. | The volume control of the amplifier is set to its minimum position | • Adjust the volume control to the desired level. |
| Distorted sound. | The recording level is too high | • Select the appropriate recording level. |
| Previously recorded sound has not been erased. | Erase head is dirty. | • Clean the head. |
| Sound output is hoarse or unsteady. | Heads are dirty | • Clean the heads. |
| Tape is damaged. | • Try operation with a new cassette, if there is no problem with the new cassette, discard the damaged cassette. | |
| Poor sound quality (especially in the high treble and low bass ranges) | The correct Dolby noise-reduction button is not set. | • Set it to the correct position |
| Sound is low, poor tone, intermittent sound, noise. | Heads, capstan and/or pinch roller are dirty or tape is damaged. | • Clean the heads, capstan and/or pinch roller, or try a new cassette. |
| Recording is not possible. | The recording level control is at the "0" position. | • Select the appropriate recording level. |
| One of the edit-recording Indicators is illuminated. | • Switch OFF the indicator by pressing the tape-to-tape recording tape-speed selector. | |
Troubleshooting Guide
(continued)
| Problem | Probable cause(s) | Suggested remedy |
| While listening to FM broadcasts | ||
| An unusual hissing noise is heard when listening to broadcasts in stereo, but not heard when listening monaurally. | Due to the differences between a monaural and a stereo signal, a higher level of signal strength is required for proper stereo reception. If the signal level is low, a hissing noise may be produced on the stereo channel. | Try reducing the treble sound by using the treble control of the amplifier.Set for monaural reception to reduce the hiss.Note, however, that the broadcast will not be heard as stereo.Try changing the location, height and/or direction of the antenna.If an indoor antenna is being used, change to an outdoor antenna.Try using an antenna with more elements. |
| Noise is excessive in both stereo and monaural broadcasts. | Poor location and/or direction of the antenna. | |
| Transmitting station is too far away | ||
| The FM stereo indicator or the quartz lock indicator flickers, without completely illuminating. | Poor location and/or direction of the antenna. | Try changing the location, height and/or direction of the antenna.If an indoor antenna is being used, change to an outdoor antenna.Try using an antenna with more elements. |
| Transmitting station is too far away | ||
| Excessive distortion in the sound of stereo broadcasts. | Nearby building or mountain.[Multipath distortion is being caused by the mutual interference of broadcast signals received directly from the transmitting station (direct waves) and signals being reflected from nearby buildings or mountains (reflected waves).] | |
| Sound is distorted, "popping" noise is heard, and/or the volume level becomes low. | Broadcast signals are being disturbed by nearby automobile traffic or airplanes. | Relocate the antenna and the connection wires to a place farther away from where automobiles pass. |
| While listening to AM broadcasts | ||
| An unusual "beat" sound is heard. | Unit is being used at the same time as the television set. | Switch OFF the television set, or use this unit farther away from it. |
| A low-pitched "hum" sound is heard when the broadcast is tuned. | The AM loop antenna connection wires are too close to the power cord. | Place the antenna connection wires and the power cord farther apart. |
| The power supply frequency from the power cord is modulated and heard from the speakers. | Install a special outdoor antenna. | |
| A strange hissing noise is produced continuously or intermittently. | Caused by the "discharge phenomenon" and the "oscillation phenomenon" of electric appliances (such as fluorescent lights, TV, small series-type motors, rectification equipment, etc.) | Try placing this unit farther away from such equipment.Install noise-prevention equipment on this unit or on the electric appliance. |
| While using the remote-control transmitter | ||
| The remote-control transmitter does not function. | Batteries are incorrectly placed. | • Insert the batteries so that the positive (+) and negative (−) polarities are correct. |
| The remote-control transmitter batteries are consumed. | • Replace them with new batteries. | |
| There is an obstruction between the remote-control transmitter and this unit. | • Remove the obstruction. | |
| The remote-control transmitter is not correctly facing this unit | • Face the remote-control transmitter correctly toward this unit. | |
