XE-A203U/ XE-A203A LEAD-FREE SOLDER

LEAD-FREE SOLDERThe PWB s of this model employs lead-free solder. The LF marks indicated on the PWBs and the Service Manual mean Lead-Free solder. Thealphabet following the LF mark shows the kind of lead-free solder.

Example:

(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 40C higher than that of conventional lead solder thread, the use of the exclusive-use soldering iron is rec-ommendable.

(2) NOTE FOR SOLDERING WORK

Since the melting point of lead-free solder is about 220C, which is about 40C higher than that of conventional lead solder, and its soldering capacity is inferior toconventional 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 tem-perature 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, cleanand file the tip with steel wool or a fine filer.

CHAPTER 3. MASTER RESET AND PROGRAM RESET

1. MASTER RESETTINGMaster resetting clears the entire memory and resumes initial values.Master resetting can be accomplished by using the following procedure:

The master reset can also be accomplished in the following case.

In case power failure occurs when the machine has no batteryattached to it, the master reset operation is automatically performedafter the power has been restored.(This is because if power failure occurs with no battery attached tothe machine, all the memories are lost and the machine does notwork properly after power recovery; this requires the master resetoperation.)

2. PROGRAM RESETTING(INITIALIZATION)

This resetting resumes the initial program without clearing memory.

This resetting can be operated at below sequence in PGM mode.

Note: In case power failure occurs when the machine has no batteryattached to it, the master reset operation is automaticallyperformed after the power has been restored.

0.00: Battery is OK.

L 0.00: Low battery (You have to change the batteries.)

L 0.00: No battery (You have to change the batteries immediately.)

F 12.34: Battery is OK.

L 12.34: Low battery. (L indicate instead of F.)

L 12.34: No battery. (L indicate instead of F.)

Note: NO BATTERY: When the NO BATTERY is display, the mas-ter reset is executed at the timing of POWERON after the POWER OFF.
