When playing (Unit: approx.hours)(JEITA) When using the radio (Unit: approx.hours)(JEITA) NoteWhen you use the radio, it is recommended that yo u us e a fully charged rechargeable battery or a new dry battery since more power is c onsumed by the radio than by MD playback. When to replace the batteries When the dry battery or rechargeable battery is we ak, flashing r or L OW BATT a ppears in the display. Replace the dr y ba ttery or charge the rechargeable ba ttery. The battery leve l indicator is approximate. It may be more or less than the indication dependi ng on the operating condition. NoteStop the recorder before replacing battery.

ELECTRICAL PARTS LIST .................................. 61 CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure. Notes on chip component replacement -N ever reuse a disconnected chip component. - Notice that the minus side of a tantalum capacitor may be dam- aged by heat. Flexible Circuit Board Repairing -K eep the temperature of the soldering iron around 270 ËšC dur- ing repairing. - Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). - Be careful not to apply force on the conductor when soldering or unsoldering. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead- free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. - Unleaded solder melts at a temperature about 40 ËšC higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 ËšC . Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! - Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. - Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. 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 s upplied with this recorder. Do not use any other AC power adaptor since it may cause the recorder to ma lfunction. -C onnect the AC power adaptor to an easily accessible AC outlet. Should you notice an abnormality in the AC power adaptor, disc onnect it from the AC outlet immediately. - The recorder is not disconnected from the AC power s ource (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 l ong time, be sure to disconnect the power s upply (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. Polarity of the plug SAFETY-RELATED COMPONENT WARNING!!
