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 abreakdown 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 landseparation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWBwhen 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 tipafter 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 BATTERYIS REPLACED BY AN INCORRECT TYPE.

PROPERLY DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.

• Max. number of drawers : 1

• The drawer consists of :

(1) Drawer box (outer case) and drawer

(2) Money case

(3) Coin case

(4) Lock (attached to the drawer)

[SPECIFICATION]

1) DRAWER BOX AND DRAWER

2) MONEY CASE

Layout:

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 degreescounter clockwise. To unlock, insert the drawer lock key and turn it 90degrees clockwise.

• Key No: SK1-1

8. BATTERY1) MEMORY BACK UP BATTERYFor 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 batteries (3AA) 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" isoff.

2) LOW BATTERY

Low battery indication will appear on the left side of display when thebattery 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 fallsbelow a certain level, or if a power failure occurs with no batteriesinstalled, the memory contents cannot be retained. The CPU judges itas no battery and performs the master reset. In this case, all the set-tings and registrations are cleared. If, however, the power is continu-ously supplied to the AC cord, the memory contents are retained.

Low battery : Batteries are installed, but the voltage is low. Memoryback up can be done.

No battery : Batteries are not installed or the voltage is extremely low.The master reset is executed when a power failureoccurs, when the batteries are not properly changed.

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

CASE 1: When any numeric entry & item entry is not done or just afterfinalization. The machine can indicate the battery condition. (Always)

CASE 2: When numeric entry or item entry is done.Battery condition does not appear.Except when power is restored after power failure, theLow 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.

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

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

CHAPTER 3. MASTER RESET

Master reset:Clears all the memory and initializes each preset parameter.

The master reset should be performed by using the following procedure.

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. (Specif-ically, plugging in the machine.)

Note 3) In case a power failure occurs when the machine has nobattery installed, the master reset operation is automati-cally performed after the power has been restored.
