Installing the Adapter
1. Set POWER=OFF. 2. Connect the adapter cord to the socket on the back of the calculator. 3. Plug the adapter into an electrical outlet. 4. Set POWER=ON, PRT, or IC. Warning: Using any AC adapter other than the appropriate TI adapter may damage the calculator and void the warranty.
Installing the Paper Roll
To avoid paper jams, use quality bond paper. A 2-inch roll of quality bond paper is included with your calculator. 1. Set POWER=ON. 2. Cut the end of the paper squarely. 3. Holding the paper so it unrolls from the bottom, insert the end of the paper firmly into the slot on the back of the calculator.

Replacing the Ink Roller

If the printing becomes faint, you may need to replace the ink roller. 1. Set POWER=OFF. 2. Remove the clear plastic printer-compartment cover. (Press down and push back to slide the cover off.) 3. Remove the old ink roller by lifting the tab (labelled PULL UP) on the left side of the roller.
Installing or Replacing Batteries
1. Set POWER=OFF. 2. If the AC adapter is connected, unplug it. 3. Turn the calculator over and remove the battery compartment cover. 4. Remove the old batteries. 5. Position new batteries as shown in the diagram inside the battery compartment. Pay close attention to the polarity (+ and symbols). 6. Replace the battery compartment cover. 7. Set POWER=ON, PRT, or IC. Texas Instruments recommends you use alkaline batteries for longer battery life. 4. While feeding the paper into the slot, press & until the paper is in position. 5. Lift the blue metal paper holder so it extends behind the printer compartment. 6. Place the paper roll on the paper holder. 7. To print, set POWER=PRT or IC. Note: To prevent damage to the printer (which may void the warranty), set POWER=ON rather than PRT or IC when operating the calculator without paper.
4. Position the new ink roller and gently press down until it snaps into place on both sides. 5. Replace the cover. 6. Set POWER=ON, PRT, or IC. Warning: Never refill or moisten the ink roller. This may damage the printing mechanism and void the warranty.

Displays and prints the value in memory, but does not clear the memory. F Subtract from Memory. Subtracts the displayed value from the memory. If a multiplication or division operation is pending, F completes the operation and subtracts the result from memory. N Add to Memory. Adds the displayed value to the memory. If a multiplication or division operation is pending, N completes the operation and adds the result to memory.

F (floating decimal) Varies the number of decimal 0 (fixed decimal) Shows 0 decimal places. 2 (fixed decimal) Shows 2 decimal places. TAX SET Lets you enter the tax rate. You cannot perform calculations if TAX=SET. CALC Lets you perform calculations.

% deletes the rightmost digit if no operation key was pressed. 2 clears an entry if no operation key was pressed. Pressing the opposite operation key cancels an entry if an operation key was pressed. (9,., N, and F only.) 9 restores the value to the add register after Y. N restores the value to the memory after 0.

In Case of Difficulty

1. If the display becomes dim or the printer slows or stops, check that: 0 The batteries are fresh and properly installed. 0 The adapter is properly connected at both ends and POWER=ON, PRT, or IC. 2. If there is an error or the calculator does not respond: 0 Press 2. Repeat the calculation. 0 TAX=CALC. 0 Turn the power off for ten seconds and then back on again. Repeat the calculation. 0 Review the instructions to be sure you entered the calculations correctly. 3. If no printing appears on the tape, check that: 0 POWER=PRT or IC. 0 TAX=CALC. 0 The ink roller is snapped firmly in place and has not run out of ink. 4. If the paper jams: 0 If near the end, install a new roll of paper. 0 Make sure you are using quality bond paper.

Correcting Entry Errors

Error and Overflow Conditions and Indicators
An error condition occurs if you divide by zero or calculate a selling price with a margin of 100%. The calculator: 0 Prints 0. and a row of dots. 0 Displays E and 0. An overflow condition occurs if a result has too many digits for the calculator to display or print. The calculator: 0 Displays E and the first 10 digits of the result with a decimal point 10 places to the left of its correct position. 0 Prints a row of dots and then prints the first ten digits of the result with the decimal shifted 10 places to the left of its correct position. 2 clears any error or overflow condition. The memory is not cleared unless the error or overflow occurred in a memory calculation.
