ELECTRONIC PRINTING CALCULATOR

Notes for handling Lithium batteries:

CAUTION

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Disposethe used batteries according to the manufacturer's instructions.

To insure 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 SHARP repair service.
5. If the unit is operated from AC power only, without installing the memory protection battery, the set tax rates and memory contents (including GT memory) will be cleared if the power plug is removed from the outlet. This will also occur when the memory protection battery is replaced.

INSTALLING OF BATTERY FOR MEMORY PROTECTION

Before using for the first time, remove the attached lithium battery, and install it in the equipment according to the following procedure.

If the power cord is unplugged by accident when operating with AC power only, the set tax rate and the contents of memory will be lost.

1) Turn the power switch "OFF" and unplug the power supply plug from the outlet.
2) Remove the battery cover on the back of the unit. (Fig. 1)
3) Wipe the battery well with a dry cloth and place the plus "+" side upward. (Fig. 2)
4) Replace the battery cover by reversing the removal procedure.

Fig. 2

5) Press the RESET switch on the back of the unit (See page 9).

After battery installation

• Connect the power supply plug to an outlet and turn the power switch "ON".
  Check that "0." is displayed. If "0." is not displayed, remove the battery, reinstall it, and check the display again.
• On the battery replacement date label found on the back of the unit, write down the month and year when the battery is installed, as a reference for the next battery replacement.

OPERATING CONTROLS

POWER SWITCH; PRINT / ITEM COUNT MODE SELECTOR:

"OFF": Power OFF

Power ON. Set to the non-print mode.

"P": Power ON. Set to the print mode.

"P·IC": Power ON. Set to the print mode.

Each time + or - is pressed, in the case of additional and subtraction, or M^+ or M^- is pressed, in the case of memory calculations, the associated item counter is incremented by one. Select the "P-IC" position to print the counter values.

• The count is printed when the calculated result is obtained.
• Pressing of * , C/CCE C/CCE 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 SELECTION:

"F": Floating.

"63210": Fixed.

"A": Add mode.

ROUNDING SELECTOR:

"An answer is rounded up.
"5/4": An answer is rounded off.
"An answer is rounded down.

GRAND TOTAL / RATE SETTING MODE SELECTOR:

"GT": This selector will accumulate the following: (^* + ^n will be printed.)

• Addition and subtraction totals obtained with * .

Neutral, GT OFF.

"RATE SET": Set the key to position to enter (or change) the tax rate.

Appears when a number is in the memory.

• : Minus symbol

Appears when a number is negative.

: Error symbol

Appears when an overflow or other error is detected.

PAPER ROLL REPLACEMENT

Never insert paper roll if torn. Doing so will cause paper to jam. Always cut 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 (Fig. 2)
3) Lift the attached metal paper holder up and insert the paper roll to the paper holder. (Fig. 3)

Fig. 3

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

INK ROLLER REPLACEMENT

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

Ink roller: Type EA-781R-BK (Black)
Type EA-781R-RD (Red)

WARNING

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

1) Set the power switch to OFF.
2) Remove the printer cover. (Fig. 1)
3) Remove the ink roller by turning it counterclockwise and pulling it upward. (Fig. 2)
4) Install the correct color new ink roller and press it in the correct position. Make sure that the ink roller is securely in place. (Fig. 3)
5) Put back the printer cover.

Fig. 3

Cleaning the printing mechanism

If the print becomes dull after long time 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 tooth brush) lightly to the printing wheel and clean it by pressing

4) Put back the ink roller and the printer cover.

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

• Never attempt to turn the printing belt or restrict its movement while printing. This may cause incorrect printing.

ERRORS

There are several situations which will cause an overflow or an error condition. When this occurs, will be displayed. The contents of the memory at the time of the error are retained.

If is displayed at the time of the error, "..." will be printed in black and CCE must be used to clear the calculator.

Error conditions:

1. When the integer portion of an answer exceeds 12 digits.

2. When the integer portion of the contents of the memory exceeds 12 digits.

$$ (E x. \boxed {*} M) 9 9 9 9 9 9 9 9 9 9 9 9 \boxed {M +} 1 \boxed {M +}) $$

1. When any number is divided by zero. (Ex. 5 ÷ 0 =).

2. This unit is equipped with a key input buffer (12 row max.), and it may give an error message if you exceed the buffer limit by pressing keys sequentially during printing.

REPLACEMENT OF BATTERY FOR MEMORY PROTECTION

Time for battery replacement

Replace with a new battery once 2 year.

Method of battery replacement

Use one lithium battery (CR2032).

Note: When replacing the battery, the set tax rate and the memory contents will be lost. You may want to write down the tax rate and other important numbers on a sheet of paper.

1) Turn the power switch "OFF" and unplug the power supply plug from the outlet.
2) Remove the battery cover on the back of the unit. (Fig. 1)
3) Remove the exhausted battery and install one new lithium battery. Wipe the battery well with a dry cloth and place the plus "+" side upward. (Fig. 2)
4) Replace the battery cover by reversing the removal procedure.

Fig. 1

Fig. 2

5) Press the RESET switch on the back of the unit (See page 9).

After battery replacement

• Connect the power supply plug to an outlet and turn the power switch "ON".

Check that "0." is displayed. If "0." is not displayed, remove the battery, reinstall it, and check the display again.

• Reset the tax rate.
• On the battery replacement date label found on the back of the unit, write down the month and year when the battery is replaced, as a reference for the next battery replacement.

Precautions on battery use

• Do not leave an exhausted battery in the equipment.
• Do not expose the battery to water or flame, and do not take it apart.
• Store batteries out of the reach of small children.
