Instrucons and FAQ’s:

1. Turning your calculator on and o.

Your calculator is equipped with a patented ‘direct number input’ feature, which allows you to press ‘any’

key to turn your calculator on, should you press a number key, then this number will also register in the

display. The calculator is equipped with an ‘auto o’ feature and will power down by itself aer a period

of inacvity.

2. What are the COST, SELL and MARGIN keys for?

These buons allow you to calculate ‘gross prot margin’ and your required cost or sell prices. There are

3 variables - Cost, Sell and Margin, if you input two of these variables the calculator will automacally

solve the third.

Example 1.

My cost is 30, I will sell for 60 what gross prot margin am I making? –

[Input 3, 0, , 6, 0, The answer will be displayed as 50% COST SELL] –

Example 2.

My cost is 30, I want to make 50% gross prot what should I sell it for? –

[Input 3, 0, , 5, 0, The answer will be displayed as 60 COST MARGIN] –

Example 3.

I will sell for 60 and want to make 50% gross profit what should my cost be? –

[Input 6, 0, , 5, 0, The answer will be displayed as 30 SELL MARGIN] –

Aer you have solved any third variable you can review all 3 variables by pressing the , and cost sell

margin keys again.

3. What are the ‘+TAX’ and ‘–TAX’ keys for?

These buons allow you to add or deduct a user denable percentage at the touch of a buon. A

common use for these buons is too add or deduct sales tax.

Firstly you need to set the tax rate.

Example Seng a tax rate of 19% –

[Input 1, 9, The SET key is on the same key as . RATE, SET] –‘+TAX’

The tax rate is now set at 19% and will remain in the memory unl you change it even when the

calculator turns o. Now you have set you tax rate you can simply add or deduct tax easily by using the

‘+Tax’ ‘ Tax’ and -Keys

Example1 The price is 60 including 19% sales tax, what is the price exclusive of tax? –

[Input 6, 0, The answer is displayed as 50.42 -TAX] –

Example 2 The price is 60 excluding 19% sales tax, what is the price including tax? –

[Input 6, 0, The answer is displayed as 71.40. +TAX] –

You can also view the actual tax content and the total by pressing the same tax key again.

You can also review the currently programmed Tax rate by pressing and (the recall key is ‘RATE’ ‘RECALL’

on the same key as the key) the currently set tax rate will be displayed on the screen. -‘ TAX’

4. How do the memory keys work?

Your calculator has a memory and you can store a variable number, to store a number press the ’M+’ key,

you can store a simple number or an answer from a calculaon. The memory also has a running total, so

you can add and deduct numbers using the M+ and M- keys. To see the number stored in the memory or

the running total press the MRC key once. To clear the memory and reset back to zero press MRC key

twice.

Example1 Store the answers to the simple sums 2+2 and 3+3 in the memory and calculate the total. –

[Input 2, +, 2, M+, 3, +, 3, M+] now press the MRC key once, the correct answer of 10 will be displayed.

Example 2 Use the memory to add these number together 5, -6, 8,9,- –4.

[Input 5, M+, -6, M+, 8, M+, 9, M+, -4, M+] now press MRC once and the correct answer 12 will be –

displayed. To clear and reset your memory press the MRC key twice. Whenever a number is stored in the

memory an ‘M’ will show on the display.

5. What does the C/CE key do?

CE means clear entry pressing this will remove you last entry but not your whole sum.

C means cancel, pressing the key again will cancel your whole calculaon.

6. What does the do?

This is the backspace or delete key, pressing this deletes the last digit you entered.

7. What is the switch marked for?

This switch is the round up/down switch, there are 3 posions, the rst is marked with the arrow poinng

upwards, on this seng the calculator will round all answers up. The middle seng is marked 5/4, on this

seng the calculator will use the mathemacal rule of rounding up when above 5 and rounding down

when below 5, the 3rd seng marked by the arrow poinng down will round all answers down.

IMPORTANT – the rounding and number of decimal places will be aected by the seng of the decimal

place switch see below.

8. What is the switch marked ‘A 0 2 4 F’ for?

This is the decimal place seng switch. The rst seng ‘A’ stands for Add mode, here addion and

subtracon funcons are performed with an automac 2 digit decimal this is useful when working with

currency and it speeds up data entry. i.e. If you enter 1, 0, 0, 0 then press +, you will noce that the

display shows 10.00, it assumes when you typed 1,0,0,0 you were entering 10.00 and not 1000.

The second seng ‘0’ xes the decimal place to zero places, all answers will be rounded to zero decimal

places based on the seng of your rounding key (see above)

The 3rd seng is ‘2’, as above all answers will now be rounded to two decimal places.

The 4th seng is ‘4’, as above all answers will now be rounded to four decimal places.

The 5th seng is ‘F’ which stands for oang, you answer will not be shortened and will be displayed

using the largest amount of digits the screen permits.

9. How do I change the baery?

On the back of the calculator is a circular baery compartment, use a coin or screwdriver and carefully

rotate the cover in an an clockwise direcon to unlock. Replace the battery - your calculator requires an

LR1130. Replace the cover and carefully ghten.

IMPORTANT when you change or remove the baery always perform a reset, see below. –

10. My calculator is performing strangely and requires reseng.

Locate the reset buon on the back of the calculator there is a small hole in the case marked– ‘RESET’.

Using a blunt but narrow object (the end of a paperclip or small screwdriver should do) gently depress

the reset buon. This should reset your calculator and will solve many potenal problems.

11. My calculator has stopped working what should I do? –

Firstly you try a Reset (see above), if you suspect the baery has failed then you should replace this (see

above). If you believe your calculator is faulty and you purchased it less than 1 year ago then it is covered

by a manufacturer’s warranty. Please contact your supplier for details.
