OPERATIONAL NOTES

To insure the trouble-free operation of your SHARP calculator, we recommend the following:

1. The calculator should be kept in areas free from extreme temperature changes, moisture, and dust.
2. A soft, dry cloth should be used to clean the calculator. Do not use solvents or a wet cloth.
3. Since this product is not waterproof, do not use it or store it where fluids, for example, water, can splash onto it. Raindrops, water spray, juice, coffee, steam, perspiration, etc. will also cause malfunction.
4. If service should be required, use only a SHARP servicing dealer, a SHARP-approved service facility or a SHARP repair service.

OPERATING CONTROLS

POWER SWITCH; PRINT / ITEM COUNT MODE SELECTOR:

• “OFF”: Power OFF
• “•”: Power ON. Set to the nonprint mode.
• “P”: Power ON. Set to the print mode.
• “P•IC” : Power ON. Set to the print and item count mode.
  • For addition or subtraction, each time + is pressed, 1 is added to the item counter, and each time – is pressed, 1 is subtracted.
  • The count is printed when the calculated result is obtained.
  • Pressing of * , clears the counter.

Note: The counter has a maximum capacity of 3 digits (up to ±999). If the count exceeds the maximum, the counter will recount from zero.

DECIMAL / ADD MODE SELECTOR:

• “3 2 0”: Presets the number of decimal places in the answer.
• “F”: The answer is displayed in the floating decimal system.
• “A”: The decimal point in addition and subtraction entries is automatically positioned to the 2nd digit from the lowest digit of entry number. Use of the add mode permits addition and subtraction of numbers without entry of the decimal point. Use of , and will automatically override the add mode and decimally correct answers will be printed.

ROUNDING SELECTOR:

Set Decimal Selector to 2.

4 ÷ 9 = 0.444 … , 5 ÷ 9 = 0.555 …

Note: The decimal point floats during successive
calculation by the use of or.
If the decimal selector is set to “F” then the answer is always rounded down ( ).

Note: The decimal point floats during successive calculations by the use of x or÷.

If the decimal selector is set to “F” then the answer is always rounded down (↓ ).

INK ROLLER REPLACEMENT

• If printing is blurry even when the ink roller is in the proper position, replace the roller.

Ink roller: Type EA-772R

WARNING: APPLYING INK TO WORN INK ROLLER OR USE OF UNAPPROVED INK ROLLER MAY CAUSE SERIOUS DAMAGE TO THE PRINTER.

1. Set the power switch to OFF.
2. Remove the printer cover. (Fig. 1)
3. Hold the top of the ink roller and remove the roller by pulling it toward you and then upward.(Fig. 2)
4. Install the new ink roller in the correct position. Make sure that the roller is securely in place.(Fig. 3)
5. Put back the printer cover.
   

Cleaning the printing mechanism

If the print becomes dull after a long time of usage, clean the printing wheel according to the following procedures:

1. Remove the printer cover and the ink roller.
2. Install the paper roll and feed it until it comes out of the front of the printing mechanism.
3. Put a small brush (like a toothbrush) lightly on the printing wheel and clean it by pressing .
4. Put back the ink roller and the printer cover.

Note: • Do not rotate the printing mechanism manually, this may damage the printer.

Never insert paper roll if torn. Doing so will cause the paper to jam.

Always cut the leading edge with scissors first.

1. Insert the leading edge of the paper roll into the opening. (Fig. 1)
2. Turn the power on and feed the paper by pressing it. (Fig. 2)
3. Lift the attached metal paper holder up and insert the paper roll into the paper holder. (Fig. 3)

DO NOT PULL THE PAPER BACKWARD AS THIS MAY CAUSE DAMAGE TO THE PRINTING MECHANISM.

HOW TO CONNECT THE AC ADAPTOR

This machine can also be operated on AC power by use of AC Adaptor. When the AC adaptor is connected to the calculator, the power source is automatically switched over from dry batteries to AC power source.

AC adaptor: Model EA-63A, EA-28A

CAUTION: Use of other than the AC adaptor EA-63A/28A may apply improper voltage to your SHARP calculator and will cause damage.

BATTERY REPLACEMENT (OPTION)

To Install or Replace Batteries — When the batteries become weak, the display will work but not the printer. This indicates that you should replace the batteries.

1. Set the power switch to OFF.
2. Remove the battery cover by sliding it in the direction of the arrow on the cover.
3. Replace the batteries. Be sure that the “+” and “–” marks on the battery correspond to the “+” and “–” marks in the calculator. Always put back the 4 batteries at the same time.
4. Put back the battery cover.
   5. Press the RESET switch on the back of the unit. Battery: Heavy-duty manganese battery, size AA (or R6) × 4

ERRORS
