8. BATTERY

1) MEMORY BACK UP BATTERYFor memory back up, the dry battery ULM-3 (3 pieces) 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) Insert the NEW dry batteries (3 pieces).5) Confirm the low battery symbol "L" is off.

2) LOW BATTERYLow 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 opera-tions, 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 BATTERYIf 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 thesettings and registrations are cleared. If, however, the power is con-tinuously 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 extremelylow.The master reset is executed when a power failureoccurs, when the batteries are not properly charged.

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

CASE 1: When any numeric entry & item entry is not done or justafter finalization.

The machine can indicate the battery condition. (Always)

CASE 2: When numeric entry or item entry is done.

Battery condition is not appeared.Exceptionally, at the power is restored after power failure, thelow battery & No battery indication will appear on the displayonly 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 batteryAfter 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 pa-rameter.

The master reset should be performed by using the following proce-dure.

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

2. Let the ECR be without the memory back up battery.

3. Turn the mode switch to the others of Power-off position.

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

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

5. Attach the memory back up battery to 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 tothe machine.(Specifically, unplugging the machine.)

Note 2) Power ON: Means connecting the AC power to the ma-chine.(Specifically, plugging in the machine.)

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

CHAPTER 6. SERVICE PRECAUTION

1. PRINTER

Since there are no service parts for this model printer, only the printerunit is supplied. Therefore, the printer component parts are not sup-plied and no service document is issued.

For troubleshooting of the printer, refer to the table below:

Printer life: 300 thousand lines (XE-A101: M-31)Ink roll life: 1 million characters

Phenomena Check point/possible cause Repair

• The printer motor is locked and thebuzzer sounds intermittently.

• Check if the printer cable is disconnected. • Check and repair the printer cable.

• The printer does not work properly • Check if the printer life is reached. • Replace the printer.

• Check if any foreign material is attached to theprinting type wheel or the gear section.

• Remove the foreign material. (After removingthe foreign material, set the mode switch to"REG" and press "CL" key.)

• Defective print (Lack on the upper/lower or left/right side)

• Check if the printing type is worn down. • Replace the printer.

• Check if any foreign material is attached to theprinting type wheel.

• Remove the foreign material. (After removingthe foreign material, set the mode switch to"REG" and press "CL" key.)

• Thin print • Check if the ink roll life is reached. • Replace the ink roll.

• Check if the ink roll is properly installed. • Install the ink roll properly.

• Check if the printing type wheel is worn down. • Replace the printer.

• Uneven pitch of print paper feed • Check if the roll paper size is proper. • Use roll paper as specified below;

Paper width: 57.5 0.5mmOutside diameter: ϕ80mm or lessInside diameter of paper tube: ϕ12mm or lessPaper thickness: 0.06~0.085mm

• Check if a load is applied to the roll paper duringpaper feeding. This may result from a foreignmaterials attached to the roll paper.

• Remove any foreign material.
