SETTING ON PRT IC GT
FUNCTION No printout is provided; however, the display can be printed by pressing 4. The printer provides a printout of your calculations but does not count them. The printer is on and an item count of additions and subtractions to or from the register is printed when sub-totaled or totaled. The GT position controls whether or not the totals from the independent add register are accumulated in the grand total register. Rounds the result of a calculation to the selected number of decimal places.
Truncates the result to the selected number of decimal places. Rounds the result up or down according to its value. For example, when the DECIMAL switch is set to 2, the result is rounded up if the third decimal position is 5 or more and rounded down if it is 4 or less. Rounds the result up to the selected number of decimal places. 220 P 6 PRINTER: PRT, ROUND: : DECIMAL: 2, TAX: CALC Display 0. 220. 36.66 Printout 0 C 220 P 6 = Ex.

Addition and subtraction keys

9 :. E

Add: Adds a number to the add register. Displays the cumulated result. Subtotal: Gives the intermediate total from the add register. Using this key does not affect the contents of the add register. Subtract: Subtracts a number from the add register. Displays the cumulated result. Total: Gives the total from the add register, and then clears the register.
1-5045~1.DOC English Page 3 of 6
Multiplication, division, percent and margin keys

? ' 3 > #

Multiply: Multiplies the number in the display by the next value entered. Divide: Divides the number in the display by the next value entered. Equals: Completes any pending multiplication or division operation. Percent: Calculates percentages, ratios, add-ons (e.g. of VAT), or discounts. Gross Profit Margin: Calculates the selling price of an item when its cost and gross profit (or loss) margin are known; also used to obtain a price excluding VAT. Ex. Cost: 594 Profit margin: 40% Press: # Answer: Selling price: 990 Gross profit: 396 Ex. Selling price including VAT: 252 VAT %: 20% Press: 252 # 20. 3 Answer: Selling price excluding VAT: 210 VAT: 42
Grand Total: Gives the grand total of the operations previously performed and stored in the Grand Total register. Every time a total is obtained with E it is cumulated into this register (printout shows G+) which is only cleared when / is pressed twice. During long calculations, if / is not used, this register can overflow and cause an error condition shown by E in the display. This register is only cleared by pressing / twice. Note: Set the POWER switch to GT for this function.

! "

Add TAX: Adds the stored tax rate to the value in the display. Subtract TAX: Subtracts the stored tax rate from the value in the display.

Memory keys

Calculations in the memory and in the add register are performed separately. Multiplication and division (as well as GPM operations) are automatically completed and the result printed when you press N or F. The symbol M appears on the left of the display to indicate that the memory content is nonzero.

N F ; 0

Add to Memory: Adds the displayed number into the memory. Subtract from Memory: Subtracts the number in the display from the memory. Memory Subtotal: Displays and prints the number in memory. Using this key does not affect the contents of the memory. Memory Total: Displays and prints the number in memory, then clears the memory.

AUTOMATIC FEATURES

Repeat operation: Allows you to repeat an operation using the same number without re-entering it. Press 9,., ? or ' as often as the number is to be repeated. Ex. N5 + 3 + 3 + 3 Press: 5. E Answer: 4 Ex. 20 Q 12 Q 12 Press: 20 ? 12 ? 3 Answer: 2,880
Constant: In a simple multiplication problem, the first number entered is automatically taken as the constant. When ? or ' is used more than once in a sequence ending with a multiplication, the constant is a composite multiplicand. This number is shown in the display the last time ? is pressed. In a division problem, or in a mixed sequence ending with a division, the last number entered is taken as the constant. The constant is cleared by entering a new multiplication or division problem, or by pressing 2. Ex. 5 Q 3 = 15; 5 Q 9 Press: 5 ? Answers: 15; 45 Ex. 66 P 3 = 22; N90 P 3 Press: 66 ' 90. 3 Answers: 22; N30 Ex. 495 + 20% = 594; 495 + 60% Press: 495 ? 20 > > 9 Answers: 594; 792
The constant can be used to find a reciprocal or to raise a number to a power. Ex. 1 P (8 + 12) Press: 9 E ' Answer: 0.05 Ex. 12 Q 12 Press: 12 ? 3 Answer: 144 Ex. Press: 12 ? Answer: 1,728

ERROR / OVERFLOW

An error or an overflow condition is indicated by an E at the left of the display. All keys except I and 2 are then inoperative. To continue the calculation, press I. To clear the calculator completely, press 2. An error condition occurs when any number is divided by zero. An overflow condition occurs when an accumulated total or result has more than 12 digits to the left of the decimal point.

IN CASE OF DIFFICULTY

Be sure the power cord is properly connected and the POWER switch is set to PRT. If the calculator still does not power-up, try a different wall outlet. If you are getting calculation errors or if the calculator does not respond to keyboard entries: 1. Press 2. The display should be 0. 2. Check the switch settings. The most common positions are: POWER: PRT, ROUND: 5/4, DECIMAL: 2, TAX: CALC. 3. Turn the POWER switch off for 10 seconds, then on and try the calculation again. If you are getting a faint printout or none at all: 1. Be sure the POWER switch is set to PRT, IC, or GT. 2. Check the ink roller for proper installation and sufficient ink supply. Replace or reinstall as indicated. If none of the above procedures corrects the difficulty, make a last check with a new ink roller before returning the calculator for service to your Texas Instruments retailer.
