Selecting fine audio equipment such as the unit you've just

purchased is only the start of your musk:a] enjoymonr. 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 Eleetmnics 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 distortiou---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 asafe kvd:

• Start your volume con_at a low setting.

•Slowly increase the sound until you can hear it comfortably

and clearly, and without distortion.

Once you have _acomfortable round level:

•Set the dial and leave it them.

Taking a minute to do this now will help m 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.

INSTALLATION

When installing the deck, avoid locations with

high temperatures or humidity, and make sure

that the deck receives adequate ventilation.

•Do not install the deck in locations subject to direct sunlight, or

near a space heater or other heating device, as this may cause

damage to the finish or internal parts.

•Malfunctions may also result if the deck is installed in an ex-

cessively humid or dusty location. Avoid installing the deck

next to kitchen counters or other locations subject to oily

smoke or humidity.

•If the deck is placed directly on top of an amplifier, it may pick

up humming or other noise. Also, if the amplifier generates a

large amount of heat, the deck may malfunction.

•If the deck is located near a television set, it may pick up inter-

ference noise, which will be recorded as awhistling sound on

the tape. If this happens, move the deck further away from the

television set or turn the television set off when operating the

deck.

•Do not place a cloth over the deck, or block the ventilation slots

in any way. The ventilation slots on this deck are necessary to

keep internal parts cool. If they are blocked, the deck may mal-

function.

CONDENSATION

When the deck is moved from a cold location to a warm location,

or when the temperature of the room changes suddenly, conden-

sation may form on the mechanical parts. This can adversely af-

fect the performance of the deck. If condensation forms, wait for

about one hour to allow the deck to adjust to the room tempera-

ture. To prevent condensation when heating a room, raise the

temperature slowly.

THE POWER SWITCH IS SECONDARY CONNECTED AND

THEREFORE DOES NOT SEPARATE THE UNIT FROM MAINS

POWER IN STANDBY POSITION.

MAINTENANCE

._. _

1CLEAN|NG THE HEADS" PINCH ROLLERSlAND CAPSTANS

The heads, pinch rollers and capstans are likely to get dirty quite

easily. If these parts, particularly the heads, get dirty, the high fre-

quency components of a recording will not be reproduced and the

stereo balance will be impaired, resulting in a deterioration of the

playback sound. It is therefore recommended that the head sec-

tion be cleaned regularly.

1. Set the POWER switch to STANDBY.

2. Press the eject button to open the cassette door.

3. Dip a cleaning swab in cleaning fluid and use it to wipe the

heads, capstans and pinch rollers.

NO TE:

After cleaning the head secdon, do not load a tape until the clean-

ing fluid has dried completely (about two or three minutes).

IDEMAGNETIZING THE HEADS ]

After using the cassette deck for a period of time, the heads will

become magnetized. The same effect will occur if a magnetized

screwdriver, magnet or other magnetized object is brought too

close to the heads. When the heads become magnetized, high-fre-

quency sounds will be lost during recording or playback, and in-

terference noise may also occur. The heads should be regularly

demagnetized with a head demagnetizer, which can be purchased

at most audio stores.

When demagnetizing the heads, make sure that the POWER

switch of the cassette deck is set to ON. However, be sure to turn

down the amplifier's volume control to its lowest position, and dis-

connect any headphones from their headphones jack. For detailed

instructions, refer to the operating instructions of the head de-

magnetizer.

CLEANING THE FRONT PANEL ]

Clean the deck regularly with a soft cloth. Ifthe front panel becomes

soiled, moisten a soft cloth with a weak solution of neutral deter-

gent (diluted in five to six parts water), wring the cloth well, and

wipe the panel clean. Never use volatile cleaners like thinners,

benzine or alcohol because they will damage the panel finish.

ICHECK CASSETTE BEFORE USE ]

IAUTOMATIC TAPE SELECTOR FUNCTION I

This cassette deck is equipped with an automatic tape selector

function which utilizes the sensor holes on the tape cassette to

determine the type of tape being used. The deck is then set to

match the tape recording bias and equalization.

NO TES :

•When using TYPE IV (Metal) tapes, make sure that the tapes

have sensor holes.

•Make sure that the sensor holes on the cassette are not

blocked; otherwise the tape selector mechanism will not func-

tion properly.

•Do not use TYPE III (FeCr) tapes.

•Leader tape (which cannot be recorded on) is I_rovided at the

beginning of a cassette tape. Let the tape run for about 5 sec-

onds before starting to record, to allow the leader tape to clear

the recording head.

•Do not leave a cassette tape exposed to the environment.

Store the cassette in its case after use so that dust and dirt do

not adhere to the tape, and so the tape will not get slack. Store

tapes in a location free from magnetism, dust, dirt, oil, heat and

humidity.. "

•Because C-120 tapes are verythin, they can easily jam in the

pinch rollers and capstan, and they often are subject to

other problems such as irregular winding. It is best not to

use them with this deck.

•If cassette tapes are irregularly wound, the tape may get

jammed in the rollers. This can cause damage to both the tape

and the deck. If you are not certain whether the tape is wound

evenly, fast forward or rewind the tape from beginning to end.

to make sure that the tape is properly wound.

< RRB1150>

Check the following items before loading acassette tape:

Is the tape loose, or is some of the tape outside

the cassette?

If some of the tape is loose or projecting outside the cassette

shell, the tape may not properly enter between the capstan and

pinch roller. This will prevent the tape from being loaded properly,

and may even damage the tape itself, In such cases, insert a pencil

into the reel hole and take up the slack (Fig. A).

Some cassette tapes come with a plastic or thick paper stopper to

prevent the tape from becoming slack. Remove this stopper when

loading the cassette and replace it after using the cassette.

Are the accidental erasure prevention tabs intact?

These tabs allow you to prevent important recordings from being

erased accidentally. When the tab on the cassette shell is broken

off (Fig. B), it is not possible to activate the recording function, so

valuable recordings will not be erased by mistake.

To rerecord on a cassette whose tab has been broken off, simply

stick a piece of doubled adhesive tape over the hole (Fig. C).

When using TYPE IV (Metal) or TYPE II (High/CrO z) tapes, be care-

ful not to block the sensor holes with the tape (Fig. D, Fig. E). If the

holes are blocked, the automatic tape selector mechanism will not

operate correctly.

NO TES:

•The accidental erasure prevention tab for each side is the one

located on the top left when the side that you want to protect is

facing you.

•When breaking off the tab, do not use a magne_'zed screw-

driver.

DOLBY NR

•Dolby NR Systems

Dolby NR systems are designed to reduce the amount of tape l_tss,

mainly in the treble components. During recording, the high-

pitched pianissimo sou_ which are most characteristic of

audible noise are boosted, and during playback, only these

boosted sections are attenuated, so that tape sound is returned to

normal. As a result, the noise is attenuated by an amount equal to

the boosting in the treble range. The Dolby B-type NR system re-

duces noise in the treble range, cutting tape hiss and expanding

the dynamic range. The Dolby C-type NR system is even more ef-

fective in reducing noise, as it reduces noise from the mid-range

and treble range.

NOTE:

When a tape has been recorded using the Dolby B-type or C-type

NR system, make sure that the DOLBYNR switch is set to the same

position during playback.

FRONT PANEL FACILITIES

IREVERSE MODE SWITCH (REV MODE)

There are three settings:

One way mode = position

When the switch is set to this position, playback or recording is

performed on one side of the tape only. When the tape reaches

the end of the side, it stops automatically (auto stop function).

Two way n_'de _position

When the switch is set to this position, playback or recording can

be performed on both sides of the tape. When the tape reaches

the end of the first (forward) side, its direction is automatically

reversed, and playback or recording continues on the other

(reverse) side. When it reaches the end of the reverse side, the

tape stops automatically (auto stop function), if playback or re-

cording is started from the reverse side, the tape will stop when it

reaches the end of that side.

Repeat mode _position (RELAY/SKIP)

When the switch is set to this position for playback, both sides of

the tape are played back repeatedly until the stop (11) button is

pressed, or until the tape has been repeated 15 times (16 sides). If

the pause button is pressed to pause the tape, and then playback

is restarted, the repeat mode starts over from the beginning, and

will repeat the tape 15 times (sixteen sides).

When the switch is set to this position for recording, both sides

are recorded and then the tape stops, as described above for the

two way mode.

NOTE:

If Deck I and II are loaded with tapes, each tape will be played

using relay playback.

Rewind autoplay engaged when the REWIND AUTO PLAY button

Tape counter =Time counter

•Tape counter

Different counters are provided for DECK I and II. The number

of a counter increases/decreases as a tape runs. It is conveni-

ent if you make a note of the recorded content and range of the

counter while recording or playing back. You can then easily

locate the desired track or where you last recorded to resume

recording.

•Time counter

• This indicates the elapsed time for recording or playback.

This automatically starts counting when recording or play-

back starts. During fast-forwarding/rewinding, the counter

automatically switches to a tape counter.

• The time counter indicates only time duration of recording

or playback. When recording or playback is changed to fast-

forwarding, rewinding, or music search, the counter swit-

ches from the time counter to tape counter. When the oper-

ation returns to recording or playback, the counter switches

to the time counter.

MUSIC SEARCH

(Skipping forward or backward to playback a desi[ed selection

The music search function detects blanks (longer than 4 seconds)

between selections, advances the tape in the forward or reverse

Erasure prevention tabs

The recording (e) button does not work when the erasure preven-

tion tabs of the loaded cassette tape have been broken off. (See

page 5.) Do not press the recording (•) button with unreasonable

force. When recording on both sides, make sure that both tabs are

intact.

ADJUSTING THE RECORDING LEVEL

The adjustment of the recording level is the most important factor

in achieving good recording results. A high level provides a good

signal-to-noise ratio and dynamic range, but an excessively high

level distorts the sound. If the level is set too low for fear of sound

distortion, irritating tape hiss will mar the recording. The charac-

teristics of tapes differ depending on the manufacturer and the

type of tape. Set the REC LEVEL control so that the level meter's

the audio source and type of tape used. In order to obtain the

best possible results, set the recordieg level after actualtesting.

Listen to your recordings, and adjust the level as necessary.

The level meter may react differently during recording and

/ilayback of the same tape. This is due to differences in tape

sensi_vity, and creates no problem.

RECORDING MUTE I

Use this function to create the 4.5-second blanks required for

proper operation of the music search function.

•Press the recording mute (O) button during recording and the

deck will create a blank space by recording e section which

contains no signal for approximately four seconds. The deck

will then enter recording standby mode.

• To create a blank which is more than four seconds long, hold

the button down for the desired length of time. When the but-

ton is released, the deck will enter recording standby mode.

•To resume recording, press the pause ( II ) button or the play-

back (),or •) button.

I ERASING A TAPE ]

To erase the recorded contents of a tape, load the tape in DECK II

and follow the procedure below.

1. Set the REC LEVEL control to the MIN position.

2. Press the recording (e) button.

3. Press the playback (1_ or <1) button or the pause (II)

button.

ITAPE COPYING (from DECK I to DECK II) I

• The tape copying function permits you to copy the contents of

a tape from DECK I to DECK 11.

•The SYNCHRO COPY button is used to select either normal

speed copying, or high-speed copying (copying at twice the

normal playback speed).

1. Load s tape for playback into DECK I and a tape for

recording into Deck II.

2. Set the REV MODE switch.

3. Set the tape transport direction.

•Tape copying is always performed in the direction indicated

by the tape transport indicator (1_or <1).To change this di-

rection, press the desired playback button (1_or <1),then im-

mediately press the stop (11) button.

4. Press the SYNCHRO COPY button to select either

NORMAL or HIGH speed.

NORMAL: Tape copying at normal speed allows listening dur-

ing playback (COPY indicator lights steadily).

HIGH: Tape copying at twice the normal be speed (COPY

indicator flashes). Playback will still be audible.

To stop copying

Press the stop (11) button of either deck. Both decks will stop.

NOTES:

•The tape in DECK II will be copied with the same type of

DOLBY NR as DECK rs tape, regardless of its own setting.

•ff a nearby television set is on whi/e high-speed copying is

being performed, a high-pitched interference sound may be

heard on the tape. In this case, either use the normal speed

copying function, or turn off the television.

•During high-speed copying, none of the opera,on buttons v_ll

function except for the stop (IE) button.

•During normal speed copying, the recording mute (O) and

pause ( II) buttons of deck II also function.

•Tape copying is cancelled when either of the two tapes reaches

the end. Therefore it is advisable to use tapes of the same

length.

•The sound quality of the copied tape will be somewhat less

than the original. Therefore when making more than one copy,

always record from the original tape (do not make a copy of a

copy).

•The recording level adjustment is not necessary during tape

copying.
