LEAD-FREE SOLDER
 
The PWB’ s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean
 
“Lead-Free” solder. The alphabet following the LF mark shows the kind of lead-free solder.

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
 
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a 
breakdown or an accident.
 
Since the melting point of lead-free solder thread is about 40˚C higher than that of conventional lead solder thread, the use of the 
exclusive-use soldering iron is recommendable.
 
 
(2) NOTE FOR SOLDERING WORK
 
Since the melting point of lead-free solder is about 220˚C, which is about 40˚C higher than that of conventional lead solder, and its 
soldering capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This 
may cause land separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering 
iron from the PWB when completion of soldering is confirmed.
 
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
 
 
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron 
tip after com-pletion of soldering work.
 
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
 
 
 
NOTE FOR INITIAL INTRODUCTION
 
Since the operation is failed if there is a monitor of the same IP address setting in the connected network environment, 
perform the LAN connection setting and then connect to the network.
 
 
INITIALIZATION
 
This monitor can remember e-mail addresses and other data.Before transferring or disposing of this monitor, initialize all settings by 
executing ALL RESET1. Executing ALL RESET2 will not reset e-mail addresses and similar data.
