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. Example: Lead-Free 5mm Solder composition code (Refer to the table at the right.) a Solder composition Solder composition code Sn-Ag-Cu a Sn-Ag-Bi Sn-Ag-Bi-Cu b Sn-Zn-Bi z Sn-In-Ag-Bi i Sn-Cu-Ni n Sn-Ag-Sb s Bi-Sn-Ag-P Bi-Sn-Ag p (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 completion 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. XE-A21S LEAD-FREE SOLDER CHAPTER 1. SPECIFICATIONS 1.

PROGRAM RESETTING (INITIALIZATION) Master resetting clears the entire memory and resumes initial values. Master resetting can be accomplished by using the following procedure: Procedure A: This resetting resumes the initial program without clearing memory. 1) Unplug the AC cord from the wall outlet or set the mode switch to OFF Position. This resetting can be operated at below sequence in PGM mode. 2) Let the ECR be without the memory back up battery. Procedure: 3) Wait over 1 muinite for discharging. 1) Unplug the AC cord from the wall outlet. 2) Wait over 1 muinite for discharging. 4) Set the mode switch to any position except OFF. 3) Set the mode switch to the PGM position. 5) Plugin the AC cord to the wall outlet or turn the mode switch from OFF Position to another position. 4) While holding down the FEED key, plugin the AC cord to the wall outlet. The master reset can also be accomplished in the following case. Note: In case power failure occurs when the machine has no battery attached to it, the master reset operation is automatically performed after the power has been restored. In case power failure occurs when the machine has no battery attached to it, the master reset operation is automatically performed after the power has been restored. (This is because if power failure occurs with no battery attached to the machine, all the memories are lost and the machine does not work properly after power recovery; this requires the master reset operation.)
