The contents are subject to change without notice. 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. Example: <Solder composition code of lead-free solder> Lead-Free 5mm Solder composition Solder composition code (Refer to the table at the right.) a 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. CAUTIONS THERE IS A RISK OF EXPLOSION IF THE BATTERY IS REPLACED BY AN INCORRECT TYPE. PROPERLY DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS. XE-A403 LEAD-FREE SOLDER PC-UM10M CHAPTER 1.

PROGRAM RESETTING (INITIALIZATION) Master resetting clears the entire memory and resumes initial values. This resetting resumes the initial program without clearing memory. Master resetting can be accomplished by using the following procedure: This resetting can be operated at below sequence in PGM mode. Procedure A: Procedure: 1) Unplug the AC cord from the wall outlet. 1) Unplug the AC cord from the wall outlet. 2) Set the mode switch to the PGM position. 2) Set the mode switch to the PGM position. 3) While holding down both the JOURNAL FEED key and [CL] key, plugin the AC cord to the wall outlet. 3) While holding down both JOURNAL FEED key and RECEIPT 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.)
