FOR AUSTRALIA AND EUROPE ... 220 V/230 V/240 V  
FOR THE U.S.A. AND CANADA ........................ 120 V  
FOR YOUR SAFETY  
FOR YOUR SAFETY  
Units shipped to the U.S.A. and Canada are designed for  
operation on 120 V AC only.  
Units shipped to Australia are designed for operation on  
240 V AC only.  
To ensure safe operation the three-pin plug supplied  
must be inserted only into a standard three-pin power  
point which is effectively earthed through the normal  
household wiring. Extension cords used with the  
equipment must be three-core and be correctly wired to  
provide connection to earth.  
Wrongly wired extension cords are a major cause of  
fatalities. The fact that the equipment operates  
satisfactorily does not imply that the power point is  
earthed and that the installation is completely safe. For  
your safety, if in any doubt about the effective earthing of  
the power point, consult a qualified electrician.  
PAN-EUROPEAN UNIFIED VOLTAGE  
Safety precaution for a polarized AC plug.  
However, some products may be supplied with a non-  
polarized plug.  
CAUTION : To prevent electric shock, do not use this  
(polarized) plug with an extension cord, receptacle or  
other outlet unless the blades can be fully inserted to  
prevent blade exposure.  
All units are suitable for use on supplies 220-240 V AC.  
FOR OTHER COUNTRIES ................... 110 V/220 V  
FOR YOUR SAFETY  
Units shipped to countries other than the above  
countries are equipped with an AC voltage selector  
switch on the rear panel. Refer to the following  
paragraph for the proper setting of this switch.  
AC VOLTAGE SELECTION  
This unit operates on 110-220 V AC. The AC voltage  
selector switch on the rear panel is set to the voltage  
that prevails in the area to which the unit is shipped.  
Before connecting the power cord to your AC outlet,  
make sure that the setting position of this switch  
matches your line voltage. If not, it must be set to your  
voltage in accordance with the following direction.  
AC voltage selector switch  
AC 220 V  
AC 110 V  
Move switch lever to match your line voltage with a small  
screwdriver or other pointed tool.

RECORDING LEVEL ADJUSTMENT  
The most important factor for good recording result is the recording level adjustment. If the recording level is  
set at maximum, the signal-to-noise ratio (S/N) and the dynamic range (range of sound volume) will improve,  
but if it is set too high, the sound quality will deteriorate. On the contrary when the recording level is set too low  
in order to avoid distortion, tape hiss noise becomes too evident. Even among tapes of the same type, the tape  
characteristics may differ according to maker and kind. It is therefore important to determine the optimum  
recording level for each tape used, in order to obtain good recordings by fully utilizing the tape characteristics.  
The optimum recording level depends on the type of music to be recorded and also on the type of tape used.  
Generally, adjust the recording level so that the level meters indicate around the 0 dB point for normal or  
chrome tapes or the +3 dB point for metal tapes at the highest signal level.

DOLBY HX PROFESSIONAL HEAD ROOM EXTENSION(DOLBY HX PRO)  
1. Dolby HX PRO is a professional recording bias system which are now available in some home cassette recorders that  
improving dynamic range and signal clarity for life-like sound quality.  
When recording audio signals which contain high-frequency components, these components influence the bias and  
decrease the high recording frequencies. (If the amount of the bias is high, high frequencies are decreased,while the  
amount of the bias is low, high frequencies are increased, resulting in high distortion.)  
The Dolby HX Pro system responds to high or low frequencies to regulate the oscilation of the bias level added to the  
recording head, thus providing a stable, effective bias to the audio signals being recorded.  
When an audio signal contains a large number of high-frequency components, the bias is held to a low value and  
deterioration of high frequencies is avoided, where as for low frequencies, the bias is added at a fixed rate.  
Bias is thus added at the optimum rate for both high and low frequencies.  
2. The unit incorporates the Dolby HX Pro system which automatically adjusts the bias for nomal, CrO2, and metal tapes at  
both channels independently. Since the system is automatically engaged during the recording process only, the audiophile  
can enjoy the full benefits of any tape without worrying about proper adjustment of switches and encoding/decoding  
controls.

PRINCIPLE OF DOLBY NR SYSTEM  
The Dolby NR system functions so that it automatically increases recording levels of medium and high frequencies when the  
recording signal level is lower than the specified level (encoding), and automatically reduces the output level to the normal  
level during playback (decoding). In this way, the tape hiss noise is remarkably reduced without affecting the sound quality.  
The Dolby NR system used in your cassette deck improves S/N ratio by about 5 dB at 1kHz and about 10 dB at 10 kHz B-  
type and by about 20 dB on the most frequency range in C-type. Furthemore C-type has the anti-saturation network which  
reduces the affects of high frequency saturation, improving high range frequency response.

NOTES ON CASSETTE TAPE  
Before loading a cassette tape, take up the slack in the  
tape to prevent it from becoming entangled around the  
capstan.  
After the recording has been finished, remove the tab  
to prevent the recorded contents from being erased or  
recored on accidently.  
For side B  
For side A  
To rerecord after tabs have been removed, cover with  
adhesive tape.  
Do not store the tapes in direct sunlight or near equipment that generates heat. Keep the tapes away from any  
magnetic fields.  
Do not touch the tape surface. Store the tapes in their cases after use. Dust can cause contamination of the heads  
resulting in noise.  
CLEANING THE HEAD SECTION  
Clean the head section about every 10 hours of use. Use a commercially available head cleaning tape.  
For better recordings, you should clean the head section before every recording.  
After cleaning the head section, do not load a tape until the cleared section is completely dry.  
DEMAGNETIZING THE HEAD  
Demagnetize the recording/playback head about every 10 hours of use with a commercially avaiable demagnetizer so that  
the magnetized head may not cause the sound to be deteriorated.
