ENGLISH
TIMER RECORDING/PLAYBACK-
Timer recording/playback can be made using any audio timer available on the market.
• Timer recording procedure
1. Make sure the connections are correct, especially the power supply
connections.
2. Turn "on" the power switch of each appliance.
3. Tune the desired station on the tuner.
4. Load the tape for recording. (Make sure the erase prevention tab is not
broken off; if it is, cover the hole with plastic tape).
5. Set the Oolby NR switch to the appropriate position.
6. Make sure the monitor switch to the SOURCE position.
7. Adjust the recording input level.
8. Set the starting position of the tape.
9. Set the timer switch (TIMER) to the "REC" side.
REC OFF PLAY
10. Set the audio timer to the desired time. The audio timer will turn the
power supply on at the desired time.
* With the above procedures; timer controlled recording can be made.
When the preset time comes, the power is supplied and the FM broadcast
can be recorded.
DOLBY B AND C NOISE REDUCTION SYSTEM_
■ 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.
■ Tape background noise consists primarily of high frequency informa¬
tion, 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.
• Timer playback procedure
1. Make sure the connections are correct, especially the power supply
connections. '

8. Set the audio timer to the desired time. The audio timer will turn the
power supply on at the desired time.
• With the above procedures, timer playback can be accomplished. When
the preset time comes, the power is supplied and playback will start.
Note:
• Please read the operating instructions for the timer before use.
• If the timer recording or playback is not desired, be sure to switch the
timer switch (TIMER) to "OFF".
• When using timers that allow several "on/off" operations, timer start
functioning can continue an unlimited number of times until the tape in
the machine is finished.
■ The operating principle of Dolby C NR is similar to that of Dolby B NR
except for the encoding/decoding response curves. The noise reduc¬
tion effect obtained with Dolby C NR is up to 20 dB, compared to 10 dB
with Dolby B NR. fn 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.
