AUTOMATIC SHUTOFF SYSTEM

To protect the RD-550's motor and drive mechanism against unnecessary wear, an automatic shut-off device has been built into the machine. When the supply hub stops for any reason the motor and drive mechanism will automatically shutoff after a short period of time (usually about 5 seconds). The machine is also automatically shut-off at the end of tape (PLAY, REC/PLAY, FAST FORWARD and REWIND modes), disengaging all locked buttons.

Note: Since this device will not affect the electronic circuits of the machine it will still be necessary to turn off the entire unit by pushing the power switch.

CASSETE TAPES

High-performance tapes ranging from normal to metal types are suitable for this component. In addition, tape, tension and capstan tolerance for this unit have been carefully adjusted to the specific tape thickness of C30, C60 and C90 cassettes. For this reason, the use of C120 cassettes is not recommended. As cleanness and precision are necessary for accurate sound reproduction, cassettes should always be handled with care, and kept away from dust and magnetic influences which might cause sound distortion.

Cassette tapes are provided with a safety feature which prevents against accidental erasure of previously recorded material. This feature consists of two small tabs located on both sides at the rear of the cassette housing. After a recording has been made, these tabs are removed, leaving two small, square openings which prevent further recording on that tape. (You will notice that these tabs are absent on any pre-recorded tapes you may have.) If you wish to guard against erasure on a recording you have made on a blank cassette, it is necessary to remove one or both of these tabs as follows:

1. If both sides have been recorded, insert a thin bladed screwdriver in the opening around each tab and gently pry the tab off. Be sure the tab falls free from the cassette.

2. If one side only has been recorded, place the cassette on a table just as it has been removed from the recorder, with the side recorded facing up and the exposed tape area facing you. You should then remove the tab in the left-hand corner to prevent erasure of that side of the tape.

If you later wish to record over a previously recorded tape, simply place a piece of adhesive tape over the opening. This will allow you to make a new recording. Removal of the tape after recording will again insure against accidental erasure.

The cassette tape, when wound loosely on either hub, is likely to jam around the capstan and pinch roller during recording or playback. Therefore, if the tape is loose, insert a pencil into the more tightly wound hub, and turn it with the pencil until the slack is taken up. Always be sure to check that the tape is wound tightly before inserting a cassette in your deck.

BEFORE RECORDING OR PLAYBACK

1. Be certain that power connection and connection with amplifies are properly made.
2. When recording, be sure the safety tabs on the cassette tape are not removed.
3. Be sure to unplug the microphones from the deck when recording from other sources.
4. To load the cassette tape, hold it by the sides and fit the top under the upper projecting section of the cassette holder. Then gently push in the bottom portion of the cassette tape so that the two catches on the lower holder secure the cassette snugly. To unload the cassette, hold it by the sides, and first detach it from the lower holder by pulling gently. Then detach from the upper holder.
5. Be sure to attach the protection cover to the tape holder when the unit is not in use.

RECORDING

• When recording with microphones, the microphone plugs must be inserted properly into the left and right microphone jacks.

• When recording from line sources, choose the desired program (tuner, turntable, etc.) on your amplifier.

• When you wish to record using Dolby NR circuit, set the Dolby NR switch to ON position.

• Set the Tape Selector according to type of tape used.*

• Turn on the deck Power switch.

• Press REC and PAUSE buttons simultaneously.

• Adjust the recording level for left and right channels with Recording Level control so that the level indicator reading does not exceed 0dB position too frequently. (See figure.)

PEAK LEVEL INDICATOR

-15 -12 -9 -6 -3 0 +3 +6 +9 dB L || || || || || || || || || || || || || || || | -15 -12 -9 -6 -3 0 +3 +6 +9 dB

1. After adjusting recording level, press the PAUSE button again to put the unit into recording mode and to start the tape.
2. Be careful to watch the level indication during recording as well. PAUSE button may be used to halt recording temporarily.
3. Press STOP button when recording is finished. When the end of the tape is reached, the REC button will automatically disengage and the tape stops.
   * When setting the Tape Selector, also set the Bias Fine-adjust control to the appropriate position. See "TAPE SELECTOR SETTING GUIDE" for optimal setting.

PLAYBACK

1. When using Dolbyized tapes, set the Dolby NR switch to ON. For non-Dolbyized tapes, set the switch to OFF.
2. Set the Tape Selector to match the type of tape used.
3. Turn on the power switch on your amplifier, keeping its volume control set to minimum. When using headphones connected to the tape deck, the amplifier is not necessary.
4. Turn on the Power switch on the deck.
5. Depress PLAY button and play-back will begin.
6. To momentarily halt playback, depress the PAUSE button. When you wish to end playback, press the STOP button. When the tape comes to an end, it stops automatically and playback mode is disengaged.

HEAD CLEANING

The most frequent cause of failure to record in one or both channels, or of weak, distorted sound, is dirty tape heads and capstan. So, be sure to clean the heads, capstan, pinch roller and tape guides as often as possible using a "Q" tip dipped in ordinary rubbing alcohol or commercial liquid tape head cleaner. Thoroughly wipe the surface of the heads, cpastan, roller and tape guide.

HEAD DEMAGNETIZING

The tape heads, capstan and tape guides gradually become magnetized with use, which will eventually affect the sound quality of your tapes. Demagnetizing should follow cleaning, but need not take place as often as cleaning, once after every 20 to 30 hours of use should suffice.

A demagnetizer may be purchased at a moderate cost from any dealer carrying tape recording accessories. Follow the instruction supplied with the demagnetizer.

Caution: Push the power switch off before you attempt demagnetizing.
