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:

(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 t han 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.

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 appear 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 dis­played (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 ex­cessive digit entry, simply press [CL] and re-enter correctly.

(P) Program:

This symbol remains on the display when the cash register is being
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 tendered is less
than the total sale amount.

(C) Change:

This symbol appears whenever the change due amount is displayed.

(L) Low battery:

This symbol appears when the power of the installed batteries is
low or you need to replace the batteries with new ones.
(see the "Maintenance" section for explanation.)

(

) No battery:

L

This symbol appears when no batteries are installed. (see "Mainte­nance" 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
positions 1 to 4.

2) LOW BATTERY

Low battery indication will appear on the left side of display when the
battery voltage is low.

CASE 1: When sitting idle or after completion of transaction.The

machine can indicate the low battery condition (Always)

CASE 2: Low battery indication will not appear during key operations,

but will appear after power up of the cash register.

[Display sample]

" 0.00 " : Battery is OK .
"L 0.00" : Low battery (You have to change the batteries.)

After finalization
"F 12.34": Battery is OK.

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

3) NO BATTERY

If the user forgets to replace the battery and the battery voltage falls
below a certain level, or if a power failure occurs with no batteries
installed, the memory contents cannot be retained. The CPU judges it
as no battery and performs the master reset . In this case, all the set­tings and registrations are cleared. If, however, the power is continu­ously supplied to the AC cord, the memory contents are retained.

Low battery : Batteries are installed, but the voltage is low. Memory

back up can be done.

No battery : Batteries are not installed or the voltage is extremely low.

The master reset is executed when a power failure
occurs, when the batteries are not properly changed.

3) LOCK (LOCK KEY : LKGIM7331BHZZ)

• Location of the lock: Front

• Method of locking and unlocking:

• To lock, insert the drawer lock key into the lock and turn it 90 degrees
counter clockwise. To unlock, insert the drawer lock key and turn it 90
degrees clockwise.

• Key No: SK1-1

8. BATTERY

1) MEMORY BACK UP BATTERY

For memory back up, the dry battery ULM-3 (3 ) are needed.

1. Memory holding time:
Approx. 1 year after New dry batteries are installed.

2. Battery exchange method:
When the low battery symbol "L" lights up, replace the bat teries (3
AA) replaced by the following method;

1) Power on the ECR.

2) Mode switch turn to "REG" mode.

3) Remove the OLD dry batteries (3 pieces).

4) The nobattery symbol "L" light up.

5) Insert the NEW dry batteries (3 pieces).

6) Confirm the low battery symbol "L" and nobattery symbol "L" is

off.

XE-A102 SPECIFICATIONS

Low battery & No battery indication will appear at the most left position
of display when the battery voltage is low.

CASE 1: When any numeric entry & item entry is not done or just after

finalization. The machine can indicate the battery condition.
(Always)

CASE 2:W hen numer ic entry or item entry is done.

Battery condition does not appear.
Except when power is restored after power failure, the
Low battery & No battery indication will appear on the
display only when the battery voltage is low.
And the indication will disappear after any key entry.

[Display sample]

" 0.00" : Battery is OK.
"L 0.00" : Low battery
"L 0.00" : No battery

After finalization

"F 12.34": Battery is OK.

CHAPTER 3. MASTER RESET

Master reset:

Clears all the memory and initializes each preset parameter.

The master reset should be perfor med by usi ng the foll owi ng procedu re.

1. Turn off the power (Power OFF). (See Note 1.)

2. Remove the memory back up battery from ECR.

3. Turn the mode switch to any position other than Power OFF.

4. Turn on the power (Power ON). (See Note 2.)

When the master rest is completed, the buzzer sounds three times.

5. Install the memory back up batteries back into the ECR.
The master reset can also be accomplished in the following case.
(See Note 3.)

Note 1) Power OFF:

Means disconnecting the AC power supply to the
machine. (Specifically, unplugging the machine.)

Note 2) Power ON:

Means connecting the AC power to the machine. (Specif­ically, plugging in the machine.)

Note 3) In case a power failure occurs when the machine has no

battery installed, the master reset operation is automati­cally performed after the power has been restored.
