Power voltage is dc 9 V and fed with regulated dc power supply from external power voltage jack. Voltages and waveforms are dc with respect to ground under nosignal (detuned) conditions. Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. Signal path. F : AUDIO

Precautions
Use only the supplied AC power adaptor. Do not use any other AC power adaptor. After operating the system with the AC power adaptor, disconnect the AC power adaptor from the wall outlet if the system is not to be used for an extended period of time. The POWER switch on the left speaker does not turn the AC power adaptor off. Do not open the cabinet. Refer servicing to qualified personnel only. Do not leave the system in a location near heat sources, or in a place subject to direct sunlight, excessive dust, moisture, rain or mechanical shock. Should any solid object or liquid fall into either speaker, disconnect the AC power adaptor and have the speaker checked by qualified personnel before operating it any further. Do not use alcohol, benzine, or thinner to clean the cabinet. Although this system is magnetically shielded, do not leave recorded tapes, watches, personal credit cards or floppy disks using magnetic coding in front of the system for an extended period of time. The nameplate indicating operating voltage, power consumption, etc., is located on the side of the plug of the AC power adaptor. Install the system on a flat, level surface to prevent it from falling over or droping. Do not place valuables near it.

Power Source

(See fig. C)
The mains power source is required when the system is used.
Note on the AC power adaptor
Use only the supplied AC power adaptor. Do not use any other AC power adaptor.

Operating Instructions Manual de instrucciones

How to Use

(See fig. D) 1 2
Turn the POWER switch to turn on the system. The POWER indicator lights up. Adjust the volume with the VOLUME control.
Turn off the MEGA BASS (Walkman) or BASS BOOST (Discman, etc.) function as it may cause sound distortion.
After listening, turn the POWER switch to turn off the system. The POWER indicator goes out.

ACTIVE SPEAKER OUT

MD station
If the TV picture or monitor display is magnetically distorted
Although this system is magnetically shielded, there may be cases that the picture on some TV sets/personal computer sets may become magnetically distorted. In such a case, turn off the power of the TV set/personal computer set once, and after 15 to 30 minutes turn it on again. For the personal computer set, take the appropriate measures such as data storage before turning it off. When there seems to be no improvement, locate the system further away from the TV set/personal computer set. Furthermore, be sure not to place objects in which magnets are attached or used near the TV set/personal computer set, such as audio racks, TV stands, toys etc. These may cause magnetic distortion to the picture due to their interaction with the system. If you have any questions or problems concerning your system that are not covered in this manual, please consult your nearest Sony dealer.
