13. Power-Cord Protection – 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, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product.
15. Outdoor Antenna Grounding – If an outside antenna or cable system is connected to the product, be sure the antenna or cable 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.
16. Lightning – For added protection for this product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power-line surges.
17. Power Lines – An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

21. Damage Requiring Service – Unplug this product from the wall outlet and refer servicing to qualified service personnel under the following conditions: a) When the power-supply cord or plug is damaged, b) If liquid has been spilled, or objects have fallen into the product, c) If the product has been exposed to rain or water, d) If the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the product to its normal operation, e) If the product has been dropped or damaged in any way, and f) When the product exhibits a distinct change in performance – this indicates a need for service.
22. Replacement Parts – When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
23. Safety Check – Upon completion of any service or repairs to this product, ask the service technician to perform safety checks to determine that the product is in proper operating condition.

Ω
/ohms) in the second and subsequent units.
• Use resistors having a tolerance of with ±5%.
Use of resistors having a poorer tolerance will cause incorrect operation.
• Never short circuit the left-channel line (Vcc). Doing so will damage the main unit.
2. Operation with Parallel Connections
A number of DN-780R units can be simultaneously operated in parallel with 1 button.
Operation with parallel connections can be used with a maximum of 5 units.
Connection of 6 or more units will lead to indicator operation.
3. Cable Length
The longer the length of the cable, the more susceptible the system will be to the effects of external noise.
Keep cable lengths to 2 m or less.
Do not locate equipment that produces electrical noise in the vicinity of the cable.
Doing so might lead to incorrect operation due to the noise.
4. Do not disconnect or connect the remote control plug during operation of the unit.
The pins of the plug might cause a short circuit of the pins inside the jack which can stop the operation.
5. Pressing more than one button of the wired remote control box at the same time (for combined operations) is not possible.
A music search operation will not result from pressing the Play (1) and Fast Forward (7), or Play (0) and
Rewind (6) buttons at the same time.
6. Pressing a button of the wired remote control box and a button of the main unit, DN-780R, (for combined operations) is not possible.
Note on Connecting the Remote Control Box
When multiple sets are connected to a single remote control box, the other sets may operate erroneously when this set’s power is turned on off or when the cord is connected or disconnected from the remote control jack.
Turn off the remote control box’ toggle switched (SW101, 102, ...) when turning this set’s power on or off or when connecting or disconnecting the cord from the remote control jack while other sets are connected to the remote control box.

Handling Precautions
• C-120 cassette tapes
C-120 cassette tapes are not recommended as they use a very thin tape base which may become tangled around the capstan or pinch roller.
• Tape Slack
Before putting a tape into the deck, take up any slack with a pencil or your finger tip. This precaution prevents the tape from becoming entangled around the capstan or pinch roller.
A
2
Storage Precautions
• Do not store cassette tapes in a place where they will be subject to:
• Extremely high temperature or excessive moisture
• Excessive dust
• Direct sunlight
• Magnetic fields (near TV sets or speakers)
• To eliminate tape slack, store your cassettes in cassette cases with hub stops
2
Accidental Erasure Prevention
• All cassettes have erasure prevention tabs for each side. To protect valuable recordings from accidental or inadvertent erasure, remove the tab for the appropriate side with a screwdriver or another tool.
• To record on a tape whose erasure prevention tabs have been removed, cover the tab holes with adhesive tape.
AUTOMATIC TAPE SELECTION
This Stereo Cassette Deck contains an automatic tape selector which automatically selects the optimum bias and equalization for the tape in use.
This is accomplished by detection of the tape type detections holes in the cassette housing.
Erasure prevention tab for side A
Erasure prevention tab for side B
• If a tape without tape type detection holes is used, the deck will be set for normal tapes.

(1).
NOTE :
In the relay play mode, it is not possible to perform the play operations simultaneously on Decks A and
B. If one of the decks is set to the play mode while the other deck is already in the play mode, playback is performed on the deck that has just been set to the play mode and stops on the other deck.
2
TWIN OUTPUT
With the DN-780R, it is possible to play tapes simultaneously on decks A and B and output their signals at the same time.
When both decks A and B are played, the signals for deck A are output from the DECK A LINE OUT jacks, and the signals from deck B are output from the DECK
B LINE OUT jacks..
• The DECK B LINE OUT jacks are exclusively for the deck B signals.
• The DECK A LINE OUT jacks are for both the deck
A and deck B signals when deck A line output select switch set to “A+B”.

DOLBY B AND C NOISE REDUCTION SYSTEM
2 The Dolby noise reduction system substantially reduces the tape background noise (hiss) inherent in the cassette medium. Dolby B NR is most widely in use. However Dolby C NR is a much more recent development and represents significant improvements over Dolby B NR.
2 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 midand 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.
2 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.
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, CrO
2 and Metal tape.
The Dolby HX-PRO headroom extension system functions during recording to raise the saturation level in the treble range. Therefore, most of the treble range components distorted or lost during recording on conventional cassette decks are more faithfully recorded on the new DENON cassette deck.
Features of the Dolby HX-PRO Headroom
Extension System
(1) Performance of Normal and CrO
2 tapes can be improved to very close of that offered by Metal tape.
(2) The dynamics in the treble 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 audio systems.
(4) The system functions whether the Dolby B/C NR system is engaged or not.
MAINTENANCE
2
Head cleaning
After long usage, tape coating or dust may adhere to the heads, causing deterioration of sound.
Therefore, the parts depicted in the illustration should be cleaned regularly. Use a cotton swab moistened with a tape head cleaning solution
(such as alcohol).
NOTES :
1. Some cleaning cassettes on the market have a 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.
2
Cleaning the Pinch Rollers and Capstans
If the pinch rollers 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).
2
Demagnetizing the Heads
The heads will become magnetized after long usage or if strongly 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 treble components on pre-recorded tapes in combination with added noise.
Thus, the heads should be demagnetized at regular intervals. (Head demagnetizers are separately available from your dealer.)
2
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.
