(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

18、 solder melts at a temperature about 40 C 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 C . Caution: The printed pattern (co

19、pper 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

20、only unleaded solder but unleaded solder may also be added to ordinary solder. 1. SERVICING NOTES. 4 2. GENERAL. 5 3. DISASSEMBLY 3-1. Disassembly Flow . 6 3-2. Case (Lower) . 7 3-3.

For use in your house: Do not use any other AC power adaptor since it may cause the recorder to malfunction. Connect the AC power adaptor to an easily accessible AC outlet. Should you notice an abnorm

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
