Additional information Precautions On safety Do not put any foreign objects in the DC IN 3V jack. On power sources • Use house current, nickel metal hydride rechargeable battery, LR6 (size AA) battery, or car battery. • For use in your house: For the supplied battery charging stand, 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. Polarity of the plug • Connect the AC power adaptor to an easily accessible AC outlet. Should you notice an abnormality in the AC power adaptor, disconnect it from the AC outlet immediately. • 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. On heat build-up Heat may build up in the recorder if it is used for an extended period of time. This, however, is not a malfunction. 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. 74 On the headphones/earphones Road safety Do not use headphones/earphones 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. Preventing hearing damage Avoid using headphones/earphones 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. 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 remote control/rotary commander The supplied remote control/rotary commander is designated for this recorder only. You cannot use the recorder with a remote control supplied with other equipment. Note on charging • The supplied battery charging stand can be used only with this recorder. Any other models cannot be charged. • Do not use the supplied battery charging stand to charge any other battery besides the supplied one or the one designated for it (NH10WM). • Be sure to use the supplied AC power adaptor. • Charge the rechargeable battery at a temperature of +5° C (+41° F) to +40° C (+104° F). • Though the battery charging stand and the battery may become hot during the charging procedure, this poses no danger. • If you are charging the battery for the first time or after a long period of disuse, the battery may not charge up to its rated capacity. This is a normal characteristic. After you use and recharge the battery a few times, it will return to its normal charge capacity.
