PARTS GUIDE
XE-A102   LEAD-FREE SOLDER
– 2 –
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” sol-
der. 
The alphabet 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 40°C higher than that of conventional lead solder thread, the use of the exclu-
sive-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 solder-
ing 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.

 2) DISPLAY CONTENTS
Departments/PLU Code:
The department code or PLU code entered appears on the left. For
example, if the key for department 1 is pressed, "1" would ap-pear in
the extreme left position.
Repeat:
Indicates the number of times the same department key is pressed. If
an entry is repeated more than ten times, only the first digit is dis-
played (12 displays as "2").
(E) Error:
This symbol appears, accompanied by a warning beep, when an
error is made. If this occurs during a transaction because of an ex-
cessive digit entry, simply press [CL] and re-enter correctly.
(P) Program:
This symbol remains on the display when the cash register is be-ing
programmed in the Z/PGM mode.
(F) Finalization:
This symbol appears when a transaction is finalized by pressing [CA/
AT/NS], [CH] or [CHK].  
(o) Subtotal:
This symbol appears when [#/SBTL] is pressed and the cash register
computes the subtotal, and also when the amount ten-dered is less
than the total sale amount.
(C) Change:
This symbol appears whenever the change due amount is dis-played.
(L) Low battery:
This symbol appears when the power of the installed batteries is
below a certain level or you need to replace the batteries with new
ones. (see the "Maintenance" section for explanation.)
(
L
) No battery:
This symbol appears when no batteries are installed. (see "Main-ten-
ance" and "Getting Started" sections for explanation.)
In addition, the following appear when appropriate:
•  The minus sign (-) can appear in positions 2 to 8.
•  The decimal point appears in positions 1 to 3.
•  When entry of the secret code is necessary, "---" appears in 
posi-tions 1 to 4.
