(Caution: Some printed circuit boards may not come printed with the

5、 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 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

6、longer time. Soldering irons using a temperature regulator should be set to about 350 C. 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 viscou-s (sticky, less prone to fl ow) than ordinary so

7、lder 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. HOW TO CHANGED THE CERAMIC FILTERS This model is used two ceramic fi lters of CF1 and CF3. You mus

8、t used same type of color marked ceramic fi lters in order to meet same specifi cations. Therefore, the ceramic fi lter must be changed two pieces together since its supply two pieces in one package as a spare parts.
