CARE OF YOUR NEW ELECTRONIC | CALCULATOR ; The calculator ts a durable, pracision-made instrument which will provide you with years of trouble-free service. To help ensure this we recommend that the inside of the caltulator not be touched, It is also | inadvisable to subject the calculator to hard knocks, craps, and unduly strang key pressing. | Extreme cold (below O'C or 22°F), heat fsbove 40°C or 104°F) and humidity may also effect | the function of the caleviator. When you do not use the calculator for 4 iong period, take out | ;. the batteries’ to prevent damage if the batteries leak. Please make sure you switch off the ; power when you finish your calculations or intend to opan the cover to change batteries, . Should the caiculator flead service, take the unit ta the store where purchased or to a nearby | dealer. ao ee ne _— _ = Printed in Jopan IN TROIDUC TION Giear customer, Congratulations on your Purchase of this few pocket-sized persadal electronic calculator. Te operate this compact yer feature-packed calculator -- 6-digit capacity for entry and 12-cigqit products fram a double tengih display system, autornatic floating decimal point system, constants for ath faur functions, squarefpawer and reciprocal calculation capability, zero suppression and AC/DC power source choice - no spécia} training is required but we suggest you to take 2 faw minutes to become familiar with this instruction manual, lt has been written to assist you in understanding the various contro) keys and functions of the caiculator throwgé simple examples and their applications. (DISPOSABLE DRY BATTERY OR AC OPERATION This calculator operates on either dry batteries or AC with the use of the AC ADAPTOR. DRY BATTERY OPERATION With two Manganese dry batteries {UNM-d or SUM-3) it operates for approximately 10 hours COntinuously. | ven when battery power decreases, the display will merely darken but cause no miseaiculation, When | |. ¥Ou have finished your calcujation, be sure to switch off the power switch to save battery power. =| To change batteries, put the power switch off first. Slide open the battery cover and replace batteries, 1 AC OPERATION ! i If you are in a 147V area, for instance, use a T7T7V AC ADAPTOR, When you use an AC ADAPTOR of a different voltage, tt may couse damage to both the AC ADAPTOR and catculstor, Plug the applicable AC ADAPTOR ![100, 177, 220 or 24D0V) inte the AC outlet and the cord into the | | calculator, When plugged in, battery power suoply stops automatically, so battery power is not ! i tect, a a donor a ee 1 ae ler Sg eh dol ey a frerrie—r +4 ey a} dee rr lh ELECTRONIC CALCULATOR CASIO personal-mini OPERATOR'S INSTRUCTION MANUAL _ . 1 Se eee oh Se ee eT ws. bee Lema ‘aoe jest ah ee = 4 * ERE Sica P aeaeat eal Bees : aes es teat Ree Lie Saracen Seer et re 13 a ' - KCKEYSDARD ON-OFF SWITCH [@F | To switch on, move the left-hand switch ta the right; “‘O."' is displayed in the read-out and you can Starl operation immediately without depressing the MG or Te key. READ-OUT [6] B-digit capacity Digitron tube panel brightly displays gach entry, each results whether final or tater- mediate and unnecessary O's (zeroes) are suppressed. NUMERAL and DECIMAL POINT KEY (6)~{S) «© Enters numerals to the read-out. Jf the qumber includes a decimat point, use the —} key in its lagcal Sequence, For example, to enter The number $2.36, depress (1: o96 <1!) Jg' When decima! places are involved, a full floating decimat point system with whkole qaumber preéfer- ence funderflow) is applied autormatically in all calculations. : FUNCTION COMMAND and RESULT KEY 8-53 --3s-8 Commands the functions (+, —, x or +]. Depress the appropriate function keys as they appear in the written sroblam and the answer is obtained by depressing the & key. CLEAR KEY [¥ fleors keyboard entry for correction. When depressed immediately after any of the command keys (.@. Gor & }, it does not function. ALL CLEAR KEY Clears the entire machine and releases the overtiow check. FULL REGISTER VIEWING KEY fal In all caleulations, the significant digits of an answer ota displayed by depressing the Bj key and the subsequent digits, any, aré shown while depressing the @ Key. (Double length display systern.} Releasing the @@ key always re-disnlays the stqnificant cigrts. Depress the ff key before going on to the next calculation, if the whale number digits of an answer fxceed six, BASIC OPERATIONAL EXAMPLES Fress the keys in exactly the same sequence as thay appear in the problems. There is no need to depress the {@ or f key prior to starting eech new catculation, 4$ an automatic clearing is given by the new entry when you have finished the previous caiculation by depressing the GE} key.
