Frequently Asked Questions - 1231x IBICO

How to turn the calculator on or off?

The calculator turns on automatically when you press a key or when ambient light is sufficient (solar model). To turn it off, it goes into sleep mode automatically after a few minutes of inactivity.

What to do if the calculator displays nothing or shows faint digits?

First check the orientation of the batteries (LR44). If the screen remains dim, replace the batteries. Also clean the contacts with a dry cloth. The solar function may require sufficient light.

How to use the memory function?

Press M+ to add the displayed number to memory, M- to subtract it, MR to recall the value, and MC to clear memory. Memory can store a single number.

How to perform a percentage calculation?

Enter the base number, press × or ÷, then the percentage, and finally the % key. For example: 100 × 10 % gives 10.

What does the display 'E' or 'Error' mean?

An error message appears in case of division by zero or overflow (result exceeding 8 digits). Press the CE or C key to clear the error.

How to change the batteries?

Turn the calculator over, open the battery compartment (usually with a Phillips screwdriver), remove the old batteries and insert two new LR44 batteries observing polarity (+/-). Close the cover.

Does the calculator work without batteries?

Yes, if exposed to sufficient light (natural or artificial), the solar cell can power the calculator without batteries. However, batteries are needed for use in the dark.

How to clear the display?

Press the C (Clear) key once to clear the last number entered, or twice to clear all ongoing calculations. The CE key clears only the current entry.

Can I use the calculator for scientific calculations?

No, the Ibico 1231x is a basic calculator with only arithmetic operations, memory, percentage, and square root. It is not suitable for trigonometric or logarithmic functions.

What to do if a key does not respond?

Clean the keyboard with a cotton swab slightly moistened with isopropyl alcohol (with the calculator turned off). If the problem persists, it may be a mechanical defect; contact customer service or replace the device.

Operation and maintenance

Before turning on

Remove the ribbon cushion placed on the ribbon. The ribbon cushion is located under the printer cover. Check the rating label on the bottom of the calculator to see if the rated voltage corresponds to the local voltage before you plug in AC cord.

CAUTION

If this calculator is not installed and used properly (in strict accordance with this instruction manual), it may compromise its characteristics.

This calculator is made of sturdy materials, which provide adequate protection under normal usage. There is a limit to the amount of dropping this unit can withstand. Reasonable care is required to protect the display and other components.

• Do not use or place this calculator in areas of high or low temperature, high humidity, direct sunlight, or a dusty atmosphere for long periods. Excessive exposure to these conditions could result in poor performance, damage to the cabinet or functional failure of the LSI or other components. Also, avoid using the calculator near audio equipment since interference may result.
• Do not use incorrect electrical supply.
• Do not expose to physical shock or to water in order to maintain good performance.
• Do not cover the calculator when it is turned on as the unit may overheat.
• Do not open the cabinet. Do not replace original components or accessories with any that are not approved by IBICO, or carried out by unauthorized personnel.
• Do not use thinner, petrol or alcohol to clean the calculator. Use a silicone treated cloth or a cloth dampened with gentle cleaning liquid that will not damage the calculator.

How to install or replace the paper roll

1 Turn on the power switch.
2 Allow the paper holder to click into place.
3 Cut the edge of the paper roll straight with scissors for proper feeding through the printer head. Insert the edge of the paper roll into the paper slot.
4 Press the "Paper Feed" key (5) to feed in the paper until it appears through the printer.
5 Install the paper roll in the paper holder by stretching both ends of the paper holder.

Note:

• Do not over-stretch the paper holder.
• To remove the paper roll from the printer mechanism, pull the paper roll forward after cutting the paper on the paper roll side.

How to install or replace 1231X the ink roller 1232X

5 Return the printer cover to the original position.

Keyboard and switch

SWITCH INDEX

1 Print Mode, Item Counter and Grand Total

P : Calculation performed on both the display and the printer NP / AC : Calculation performed on the display only IC : Calculation with item-count, print and display GT : Calculation with Grand Total.

1231X & 1491X: Any total taken with T key is automatically accumulated to the memory. The accumulated grand total can be recalled by pressing the memory MC key;

2 Decimal Point

Calculation by pressing the T, +, -, =, % or MC keys is normally completed in the decimal point position predetermined by the decimal point selection switch. When the integral part of the entry number or calculated result exceeds the integral digits incidentally regulated by the decimal point selection, the whole integral part predominates over the decimal part.

A : Add mode. The decimal point is automatically placed before the last two digits in addition and subtraction.
0, 1, 2, 3, 4, 6 : For multiplication and division, decimal point is set to the result of the calculation. For addition and subtraction, decimal point is set to all entries.
0 : Integral number only
1:1 decimal place
2:2 decimal places
3:3 decimal places
4 : 4 decimal places
6:6 decimal places
F : Floating decimal point. Automatic floating point for decimally accurate computing.

(Depending on decimal point system. If decimal point system is in floating point mode, this switch will be neglected.)

↓ : Calculation in Round-down mode
5/4 : Calculation in Round-off mode
↑ : Calculation in Round-up mode

4Σ

.: Calculation without Sigma
Σ : Calculation with Sigma. The results of multiplication or division calculations completed by the = or % keys are automatically added to the accumulator. The sum of these accumulations is displayed by pressing Subtotal key and displayed and cleared by pressing the Total key.
