• If the leaked electrolyte gets into eyes, wash off with clean water, and consult your doctor immediately.

• If the leaked electrolyte gets on your skin or clothes, wash off thoroughly with water. • Remove batteries if not used for prolonged periods of time. • Do not leave dead batteries in the unit. • Do not mix new and used batteries and/or battery types.

To Install or Replace Batteries — When the battery power becomes weak, printing may be halted, and displayed images may disappear. If such symptoms are observed, replace the batteries with new ones.

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. Battery: Manganese dry battery, size AA (or R6) × 4

HOW TO CONNECT THE AC ADAPTOR (OPTION)

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

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-28A Make sure that you turn the calculator’s power off when connecting or disconnecting the AC adaptor.

To connect the AC adaptor, follow steps ➀ and ➁. To disconnect the AC adaptor, simply reverse the procedure.

REPLACEMENT OF BATTERY FOR MEMORY PROTECTION There are several situations which will cause an overflow or an error condition. When this occurs, “E” will be displayed. The contents of the memory at the time of the error are retained.

If an “E 0.” is displayed at the time of the error, “– – – – – – –” will be printed in red and must be used to clear the calculator. Also, in rare cases, printing may stop midway and the indication “E” appear on the display. This is not a malfunction but is caused when the calculator is exposed to strong electromagnetic noise or static electricity from an external source. Should this occur, press the key and then repeat the calculation from the beginning.

Time for battery replacement

Life of the memory protection battery is approximately 2,500 hours at 25°C(77°F) with no operation battery installed, and the AC adaptor not connected. * When the memory protection battery is weak, the date/time setting is initialised (1/1/2005, 12:00:00 a.m.). Verify the date/time setting in the date/clock display mode after replacing the operation battery or when connecting the AC adaptor with no operation battery installed. If the date/time setting is modified or incorrect, promptly replace the memory protection battery with new one. (The life of the pre-installed battery may be shorter than expected because of the time the calculator spends during shipment.)

1. When the integer portion of an answer exceeds 12 digits. 2. When the integer portion of the contents of the memory or grand total memory exceeds 12 digits. (Ex. 999999999999 1 ) 0 3. When any number is divided by zero. (Ex. 5 )

Method of battery replacement

Use one lithium battery (CR2032). Caution: Replacing the battery will clear the date and time settings, and the stored tax rate.

After battery replacement

• Connect the AC adaptor, and set the power switch to the “ON” position. Check that “0.” is displayed. If “0.” is not displayed, remove the battery, reinstall it, and check the display again. • Readjust date, time, and tax rate settings. • 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.

1) Set the power switch to the “OFF” position, and disconnect the AC adaptor.

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. 5) Press the RESET switch on the back of the unit (See “RESETTING THE UNIT”).

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.
