SECTION   GENERAL
The circuit boards used in these models have been processed using 
Lead Free Solder. The boards are identified by the LF logo located 
close to the board designation e.g. H1 etc [ see example ]. The 
servicing of these boards requires special precautions to be taken as 
outlined below. 
Lead Free Soldered Boards
example
Lead Free Solder material must be used to comply with environmental requirements of new solder joints. Lead Free Solder is available 
under the  following part numbers :
Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This 
requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.
