SAFETY  
INSTRUCTIONS  
READ BEFORE OPERATING EQUIPMENT  
This product was designed and manufactured to meet strict quality  
and safety standards. There are, however, some installation and  
operation precautions which you should be particularly aware of.  
12. Power–Cord ProtectionPower–supply cords should be routed  
so that they are not likely to be walked on or pinched by items  
placed upon or against them, paying particular attention to cords  
at plugs, convenience receptacles, and the point where they exit  
from the appliance.  
1. Read InstructionsAll the safety and operating instructions  
should be read before the appliance is operated.  
14. Cleaning The appliance should be cleaned only as  
recommended by the manufacturer.  
2. Retain InstructionsThe safety and operating instructions  
should be retained for future reference.  
15. Power LinesAn outdoor antenna should be located away from  
power lines.  
3. Heed WarningsAll warnings on the appliance and in the  
operating instructions should be adhered to.  
16. Outdoor Antenna GroundingIf 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. Article 810 of the National Electrical Code,  
ANSI/NFPA 70, provides information with regard 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 A.  
4. Follow InstructionsAll operating and use instructions should be  
followed.  
5. Water and MoistureThe appliance should not be used near  
water–for example, near a bathtub, washbowl, kitchen sink,  
laundry tub, in a wet basement, or near a swimming pool, and  
the like.  
6. Carts and StandsThe appliance should be used only with a  
cart or stand that is recommended by the manufacturer.  
17. Nonuse PeriodsThe power cord of the appliance should be  
unplugged from the outlet when left unused for a long period of  
time.  
6A. An appliance and cart combination  
should be moved with care. Quick  
stops, excessive force, and uneven  
surfaces may cause the appliance and  
cart combination to overturn.  
18. Object and Liquid EntryCare should be taken so that objects  
do not fall and liquids are not spilled into the enclosure through  
openings.  
7. Wall or Ceiling MountingThe appliance should be mounted to a  
wall or ceiling only as recommended by the manufacturer.  
19. Damage Requiring ServiceThe appliance should be serviced  
by qualified service personnel when:  
8. Ventilation The appliance should be situated so that its location  
or position does not interfere with its proper ventilation. For  
example, the appliance should not be situated on a bed, sofa,  
rug, or similar surface that may block the ventilation openings;  
or, placed in a built–in installation, such as a bookcase or  
cabinet that may impede the flow of air through the ventilation  
openings.  
A. The power–supply cord or the plug has been damaged; or  
B. Objects have fallen, or liquid has been spilled into the  
appliance; or  
C. The appliance has been exposed to rain; or  
D. The appliance does not appear to operate normally or exhibits  
a marked change in performance; or  
9. Heat The appliance should be situated away from heat sources  
such as radiators, heat registers, stoves, or other appliances  
(including amplifiers) that produce heat.  
E. The appliance has been dropped, or the enclosure damaged.  
20. Servicing The user should not attempt to service the appliance  
beyond that described in the operating instructions. All other  
servicing should be referred to qualified service personnel.  
10. Power SourcesThe appliance should be connected to a power  
supply only of the type described in the operating instructions or  
as marked on the appliance.  
11. Grounding or PolarizationPrecautions should be taken so that  
the grounding or polarization means of an appliance is not

PROPER RECORDING LEVEL  
A too high recording level can saturate the tape and cause distortion.  
On the other hand, if the recording level is set too low, soft passages  
will be marked by residual noise. A proper recording level is the  
single most important factor for making well balanced recordings.  
Note:  
The optimum recording level differs depending on the program  
source and the type of tape used.

DOLBY B AND C NOISE REDUCTION SYSTEM  
í The Dolby noise reduction system substantially reduces the tape  
background noise (hiss) inherent in the cassette medium.  
í The operating principle of Dolby C NR is similar to that of Dolby B  
NR except for the encoding/decoding response curves. The noise  
reduction effect obtained with Dolby C NR is up to 20 dB,  
compared to 10 dB with Dolby B NR. In addition, Dolby C NR uses  
an anti-saturation network and spectral skewing circuitry for a  
significant improvement in the dynamic range of the mid-to high-  
frequencies.  
í Tape background noise consists primarily of high frequency  
information, which is particularly annoying during soft passages,  
The Dolby NR system increases the level of low volume mid and  
high frequency signals during recording and reduces the level of  
these signals by an identical amount during playback, As a result,  
the playback signal is identical to the original source, but the level  
of background noise generated by the tape is greatly reduced.

DOLBY HX PRO HEADROOM EXTENSION SYSTEM  
This deck is equipped with the Dolby HX PRO headroom extension  
system. Since the system functions automatically during recording, no  
switching operation or adjustment is required. The system is effective  
with any type of Normal, High and Metal tape.  
The Dolby HX PRO headroom extension system functions during  
recording to raise the saturation level in the high frequency range.  
Therefore, most of the high frequency range distorted or lost during  
recording on conventional cassette decks are more faithfully  
recorded on the new MARANTZ cassette deck.  
Features of the Dolby HX PRO Headroom Extension System  
(1) Performance of Normal and High Position tapes can be improved  
to very close of that offered by Metal tape.  
(2) The dynamics in the high frequency range are improved  
significantly.  
(3) Since no decoding is necessary during playback, the improved  
sound can be enjoyed on any type of tape deck, including  
portable players and car aud io systems.  
(4) The system functions whether the Dolby B/C NR system is  
engaged or not.  
MAINTENANCE  
í Head cleaning  
í Cleaning the Pinch Rollers and Capstans  
After long usage, tape coating material or dust may adhere to the  
heads, causing deterioration of sound. Therefore, the parts  
depicted in the illustration should be cleaned reguraly. Use a  
cotton swab moistened with a tape head cleaning solution (such  
as alcohol).  
If the pinch roller or capstans accumulate dust, tape transport may  
become unstable, as a result from slippage, during recording or  
playback. The tape can also be damaged if it gets entangled in  
the capstan.  
Clean these parts with a cotton swab or a soft cloth moistened with  
a tape head cleaning solution (such as alcohol).  
Note:  
1. Some cleaning cassettes on the market have strong abrasive  
effects and may scratch the heads. Always use cotton swabs  
instead of cleaning cassettes.  
2. Since the use of metal tape is apt to collect more dust on the  
heads, the heads should be cleaned more often to enjoy the  
best possible sound.  
í Demagnetizing the Heads  
The heads may become magnetized after long usage or if  
storongly magnetized objects are brought near them. The result is  
a generation of noise, loss of the high frequency range, and in  
extreme cases erasure of the high frequency part on pre-recorded  
tapes in combination with added noise.  
Thus, the heads should be demagnetized at regular intervals.  
(Head demagnetizers are sparately available from your dealer.)  
í How to Demagnetize the Tape Heads  
1. Turn off the power.  
2. Turn on the demagnetizer while it is at least 30 cm away from  
the heads. Bring the demagnetizer near the heads and slowly  
move it in small circles four or five times in front of each head,  
making sure you do not touch them.  
3. Slowly move the demagnetizer away and turn it off when it is at  
least 30 cm away from the heads.  
4. For more details, please read the User Guide provided with the  
demagnetizer (optional).
