Initial operation of the device

Remove the calculator trainer and accessories from the > packaging.

Remove all possible sticky tape/foils.

The battery is already preinstalled. To protect against prema-

ture discharging an isolation strip has been placed between

the poles. Simply pull this out before initial operation.

Changing the batteries

The device requires a 3V lithium battery type CR2032, which is already preinstalled. If the display remains blank after it has been

switched on the batteries are depleted. To change the batteries

open the battery compartment on the rear panel of the device.

For this unscrew both of the screws

> ; and remove the

battery compartment cover 2). Before removing the old batteries please memorize their

position in the compartment by means of the inscription. The plus sign is visible from the outside.

Remove the batteries and replace them with fresh ones of

the same type. Thereby the plus sign must still be visible from the outside otherwise the device will not function and could be damaged.

Place the battery compartment cover

> 2) back on and screw

it down rmly.

Handling of batteries

Leaking batteries can cause damage to the calculator trainer.

If you do not intend to use the calculator trainer for a long

period of time then remove the batteries. When a battery has leaked put on protective gloves and

clean the battery compartment with a dry cloth. Do not attempt to recharge the batteries.

Switching the device on and o

To switch the device on press the > button e. In the display q the rst calculation task appears.

To switch the device o press the

> button e again.

Setting the diculty level

The training programmes oer you 3 and/or 5 dierent diculty

levels.

Press the

> button w to switch up to the next diculty level.

If the highest level was already set the device will switch back

to the lowest level.

The bar indicator 2& in the display q shows you the currently

selected diculty level. The display of only one bar indicates the lowest diculty level, if the display q shows 3 and/or 5 bars, this is an indication of the highest diculty level.

Muting the acoustic function

The acoustic function acknowledges every press of a button with a

short beep sound and after your answer entry, plays a short theme music depending on wether the entry was correct or not.

To switch the device's acoustic function on or o press the

button r.

When the acoustic function is active the

symbol lights up in the

display q.

When the function is switched o the

symbol lights up in the dis-

play q.

The training programme in particular

Here you learn details pertaining to the training programmes.

G 1 - Basic calculation operations

To select this programme press the button G 1

> j. In the display

q the rst calculation task appears. Thereby the strokes in the an-

swer indicator 2% show how many digits the correct answer has.

- 9 -

Press the . . . >

button t when you want the device to set division tasks, button y when you want the device to set multiplication tasks, button u when you want the device to set subtraction tasks, button i when you want the device to set addition tasks.

Enter the solution via the number buttons and press the

ENTER button o.

The device evaluates your entry in 3 ways:

The face is depicted as either sad (• incorrect entry) or

happy ( correct entry),

a corresponding melody is played (only when the acoustic •

function is switched on),

with a correct entry, in the display • q is shown an additional

goblet (%). When approx. 20 seconds has elapsed without an input the

task is considered unsolved and/or incorrect.

After the input of an incorrect answer the same task will be

presented to you a second time. If, after this you are still

unable to solve the task the device shows the solution in the display q and then oers you a new task.

Press the ENTER button

> o when you want to skip over the

task. If this is the rst time that the device has set this task then you will be oered a second chance here also. Then press the ENTER button o again and the device will show the solution in the display q and oers you a new task.

After every 5 tasks the device determines an evaluation of

your entries. For each solved task you receive 20 points and a goblet (%).

A higher diculty level in this programme results in the numbers

being greater.

- 10 -

G 2 - Recognize the carried out calculation operation

To select this programme press the button G 2

> 1%. In the

display q the rst task appears.

In the upper line you will see 2 numbers. Now determine

which of the 4 basic calculation types must be applied to the numbers in order to achieve the answer located in the

lower line.

Within approx. 20 seconds press the corresponding button

and then the arithmetic operator will be superimposed between the two numbers.

Press the ENTER button

> o to conrm your selection.

We have already described under G 1 how the device evaluates your entries and/or behaves when the entry is missing or incorrect. The implementation of the "second chance" and the evalu-

ation of your entries accordingly also applies here therefore we will dispense with a repetition here and with explanations

of other training programmes. A higher diculty level in this programme results in the numbers

being greater.

G 3 - Sequence recognition

To select this programme press the button G 3

> 1$. In the

display q 3 numbers appear.

Here you must recognize which logical sequence the numbers

form when read from left to right. Within approx. 20 seconds enter the next highest number in

the sequence as the answer and press the ENTER button o.

G 4 - Retention of numbers

To select this programme press the button G 4

> 1#. In the

display q a four digit number appears.

- 11 -

Memorize this number, after a few seconds the number > disappears.

Now enter, Within approx. 20 seconds, the number as the

answer and press the ENTER button o.

A higher diculty level in this programme results in the numbers

being greater.

G 5 - Sequence recognition

To select this programme press the button G 5

> 1@. In the

display q in the lower line, a number followed by an arith-

metic operator appears. Now enter, within approx. 20 seconds, for the empty eld

the number by which the term will achieve the answer shown

in the upper line.

In this programme, after the entry of an incorrect answer or if you do not enter any answer at all, the device will immediately set a new task and will not oer a second chance. In this programme a higher diculty level results in the device increasing the number of sum terms.

G 6 - Addition with memory training

To select this programme press the button G 6

> 1!. In the

display q a term appears in the upper line.

Memorize the 2 sum terms then within approx. 20 seconds,

enter the answer and press the ENTER button o. If the answer was correct you will now receive another task,

in which the 2nd sum term is hidden by a ashing segment

and is therefore not shown.

Now recall to mind the number you have just memorized

and in this way calculate the answer. Now memorize the 1st sum term of this task.

- 12 -

Enter the answer and press the ENTER button > o. If the answer was correct you will now receive another task,

in which the 1st sum term is hidden by a ashing segment. Now recall to mind the number you have just memorized

and in this way deduce the answer.

Enter the answer and press the ENTER button

> o. In this programme a higher diculty level results in the described operations being solved repeatedly.

Resetting the device

If the device functions appear to you to be impaired or it does

not behave as described in these instructions you will have to

reset it. For this press the RESET button 1* carefully with a thin, sharp object through the housing opening on the rear panel of

the device. This will return the device to its default settings.

Cleaning and care

NEVER submerse the device or its components in water or • other uids! Do not allow any liquids to penetrate the housing.

•

Cleaning the housing:

Clean the housing surface with a slightly damp cloth

Never use petrol, solvents or detergents that can damage plastics!
