Additional information On the headphones Precautions On safety Do not put any foreign objects in the DC IN 3V jack. Road safety Do not use headphones while driving, cycling, or operating any motorized vehicle. It may create a traffic hazard and is illegal in many areas. It can also be potentially dangerous to play your recorder at high volume while walking, especially at pedestrian crossings. You should exercise extreme caution or discontinue use in potentially hazardous situations. On power sources • Use house current, nickel metal hydride rechargeable battery, LR6 (size AA) battery, or car battery. • For use in your house: Use the AC power adaptor supplied with this recorder. Do not use any other AC power adaptor since it may cause the recorder to malfunction. Preventing hearing damage Avoid using headphones at high volume. Hearing experts advise against continuous, loud and extended play. If you experience a ringing in your ears, reduce the volume or discontinue use. Polarity of the plug • The recorder is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the recorder itself has been turned off. • If you are not going to use this recorder for a long time, be sure to disconnect the power supply (AC power adaptor, dry battery, rechargeable battery, or car battery cord). To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord. Caring for others Keep the volume at a moderate level. This will allow you to hear outside sounds and to be considerate of the people around you. On the MiniDisc cartridge • When carrying or storing the MiniDisc, keep it in its case. • Do not break open the shutter. • Do not place the cartridge where it will be subject to light, extreme temperatures, moisture or dust. On heat build-up Heat may build up in the recorder if it is used for an extended period of time. In this case, leave the recorder turned off until it cools down. On cleaning • Clean the recorder casing with a soft cloth slightly moistened with water or a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzene as it may mar the finish of the casing. • Wipe the disc cartridge with a dry cloth to remove dirt. • Dust on the lens may prevent the unit from operating properly. Be sure to close the disc compartment lid after inserting or ejecting an MD. On installation • Never use the recorder where it will be subjected to extremes of light, temperature, moisture or vibration. • Never wrap the recorder in anything when it is being used with the AC power adaptor. Heat build-up in the recorder may cause malfunction or damage. 42
