Though small in size, this unit is capable of performing complex calculations with arrazing speed and simplicity. Careful reading of this manual will enable you to use your new SHARP calctilator to its fullest capability. ay To insure trouble-free operation of your SHARP calculator, we recammend the following: 1. The calculator should be kept in areas free from extreme terriperature chanaes, moisture and dust. 2. A Soft, dry cloth should be used to ciean the calculator. Do not use solvents or a wet cloth, 3. tf the calculator will not be operated for an extended period of time, remove the batteries to avoid possible damage caused by battery leakage. Do not incinerate used batteries when disposing of them. 4. When you are using an optional AC adaptor, turn off the power switch prior to disconnecting the AC cord. 5. If service of your calculator is required, use only an authorized SHARP Service center, 2 CONTENTS ee * THE KEYBOARD ....... -~ .

BATTERY REPLACEMENT _ Dimming of the display indicates that the batteries should be replaced or re- charged. (The ert mast digit and right symbol part become dimmer than the other digits. Batteries: Two “AA” dry batteries or the optional Ni-Cd battery pack EA-1 BB. Ni-Cd Recharger: Modei EA-17 (optionally available}. 1. Turn off the power switch. 2. Remove the battery cover by sliding it in the direction of the arrow on the cover (Fig, 1). 3. Replace the batteries. Be sure that the “+’’ and ‘’—" mark on the battery correspond to the +" and “—"' mark in the case. (Fig. 1). 4. Replace the battery cover. Out pack (in the case of dry battery} (In the case of rechargeable battery) Fig. 1 Fig. 2 Note q 3 Ls Always replace both batteries at the same time. if the used batteries are kept in the battery compartment of the calculator, damage to the calculator by battery leakage may result. Before plugging or unplugging the AC adaptor, be sure that the power switch is in the OFF position Never use any AC adaptor except EA-17 (optionally available.) CAUTION: Use of other than the AC adaptor EA-17 may apply improper voltage to your SHARP calculator and will cause damage. “OVERFLOWERRORS dla ar a elo a * mre ae Dee Bh ee | Pg, re ee — There are several situations which will cause an overflow or an error condition. An overflow or an error is detected in the following cases, and the subsequent calculation becornes impossible. 1) When the integer portion of any result exceeds 8 digits and does not exceed 16 digits. 2) When the square root of a negative number is calculated. a / x: x <0} 3} When any number is divided by zero. {A <0) 4) When the integer portion of the quotient in percentage calculation is 17 digits. (Ex. 10000000 [=] 0.0000001 [%] ) 5) When the integer portion of a result exceeds 8 digits in memory catculation. 6) When the integer portion of a result exceeds § digits during tax and discount calculation (Ex. 99009901 101 (%) ) | In the case of 1 above, the first 8 digits of the result is divided by 105 (106,000,000) and then it is displayed on the numeral display-part, and an error symbol [.(E for a negative result) is displayed on the symbol display-part. Therefore, the decimal point of the displayed number means the unit of one hundred million. {Display of aporoximate nurrber) While as for the casas 2 to 6, the display are occupied by “0,70”, (Note) in ali the cases 1 to 6, the memory retains the contents before the overfiow error Is detected. 10 Overtiaw calculation Example | ~~ Operation | eee ke alg hy ara ahah hee ah hy ae le pe | 96, (887, 431 + 4,563, 211 96857431 431] 4563211 {=} =101,420,642 | > 1.0142064 C (1 9142064 x 10° = 107 420 640) | ‘96 385, 274 0.321 x 456 96385274 (4) .321 {x So 0026565 a = 136,921,136,897, cel» 3. 0026565 | 456 [=] 1369.2113 (1369.2113 x 108 = 136 921,130,000) it OPERATIONS | Before caiculation | ® To obtain an accurate result, be sure to perform the following operation before starting calculations.
