Calculation Function Specifications CALCULATION EXAMPLES 52 54 111 Prior to Use This calculator has been manufactured using Casio's advanced electronics technology under strict quality control conditions. • Use precautions • This calculator is composed of precision electronic components. Never attempt to take it apart. Avoid shock such as throwing or dropping. Do not subject it to sudden temperature changes. Do not leave or store it in hot, humid or dusty places.
I Power Supply and (2) Remove screw (§) and remove the battery-retaining plate. (3) Take out the both old batteries. The calculator uses two CR2032 lithium batteries for calculation/dlnpliiy ll nhu uses one CR1220 lithium battery for memory backup. If display contrast Is low nvnn when the contrast control (p. 8) adjusted to the maximum, it indicates that thct hniim inn luive become weak. Replace the batteries as soon as possible using the procedurti
2. Memory backup battery Turn off the power switch and follow the same procedure as in trm (MM nt main hnltRry replacement, beginning by removing screw (g). Replace this auxiliary Imtlmy eivnty 2 years irrespective Of main battery replacement. Note: If the main batteries for calculation/display and the auxiliary battery for memory beck up are removed at the same time, the memory contents will be lost. Be sure to keep either in place. * Never throw the old batteries into a fire.
3) Move the clasp of the RAM pack downward. Insert the pack in the socket of the main body and slide it in while holding the clasp. * Never touch the connector on PCB pad of the RAM pack. The RAM area of this calculator's data memory is 929 charactun (•|I|IMIM|MIM|H|V 1 kilobyte), but the addition of the optional RAM Pack (OR-20) Incrnnwi* Urn ninn to 2977 characters (approximately 3 kilobytes).

When the finger contacts tl\ I Ingor Input Screen, an input speed indicutoi lights up. Example: Calculate 123 X 45. (Be sure to press thec==>key when beginning a calculation.) After the first stroke of "A" is written and the finger is lifted from the screen, the input speed indicator will diminish gradually. 123X45 n 5535.
• Examples of pattern recognition by finger writing There are 48 kinds of characters (alphabet, numerals and symbols) which can be input by finger writing. Practice inputting all characters before advancing to UK; next section. Correct formations of characters are marked with " O ". Be sure that the other writing forms cannot be recognized for this unit.
Example: • Data storage format • A maximum of 60 characters can be stored on each line. (The cursor blinks up to the 55th character. After that, " • " begins to blink. • The maximum number of vertical divisions in each category is 253. • In the case of "TEL", names are automatically stored in alphabetical order.

•COutput procedure> (1) Sequential search • Prior to output First press the "All Reset" button and input the following data in the same way as described on page 36. The output procedure will be described on the assumption that the following data has already been stored. After inputting all data, select the output mode by pressing 8 key. • Use the S key to recall the data records in the order in which they were input. ("MEMO" is displayed first.
(2) Spelling search • / tsitneuns8 (I Press B after inputting the first character and the first data item record which k^i/\ with that input character will be displayed. jya$»*•»* Example: Display of TRAIN TIMETABLE. • When two or more data item records have the same initial letter, the one input first will be recalled. Example: (Output mode) (Output mode) Make sure to be in the finger mode. "MEMO" is displayed. Input of initial letter.
• SECRET function When it is undesirable for stored data to become known to others, it can be stored in a special secret area with a keyword attached. This is an information protection function used so that people who do not know the keyword cannot see the contents of this data. Example: Store the telephone number for GILBERT in the secret area. Continuing from the last operation (Input mode) 1) Select the input mode ( oa mode).
Example: Recalling the telephone number for Gl LBERT in the secret area. (Output mode) ((ES)CASI3e &ILBERT5I3 03-347-4837 * The secret area will not be designated if the 13 key is pressed without inputting a keyword, or if the keyword is incorrect. Example: (ED)CASSS Two or more keyword cannot be stored at the same time. • COMMAND function The five COMMAND functions are as follows: (1)CAPACITY command: Indicates the number of characters in the Data Bank plus the number of characters being used.
* In a unit without an optional RAM pack, L and U become 1024 when added together. * If no data is being stored (after RESET), the CAPACITY command display will show L 929: U 95 (L 2977: U 95 with optional RAM pack). This U figure of 95, represents the amount of space required to handle TEL, MEMO etc. Accordingly, after any data input, the figure which subtract 95 from the figure of U will be the number of characters of stored data. Example: Designation of the TEL for automatic display. ) lights up.
For example, when n = 4, this means that the display will change once in about 0.55 seconds. (Touch mode) OHIO lights up. (3) FINGER SPEED command • In the finger mode, designates the finger input speed. There are 9 levels for finger input speed. * By inputting n (n = 1 through 9) prior to press|m|key, the finger input speed can be changed. The following table lists the finger input speeds. (Speed time is approximate.) n 1 2 3 4 5 6 7 8 9 Speed (sec) 0.29 0.35 0.42 0.48 0.55 0.61 0.67 0.
• (4) BUZZER command • This command turns the key sound on or off. Each time & key is pressed, the mode changes to BUZZER ON or OFF alternately. • After All Reset button is pressed, BUZZER OFF is designated automatically. • Data input errors Errors sometimes occur in the Data Bank at the time of input. (1) RECORDS FULL The maximum number of RECORD divisions for either TEL or MEMO is 253.
• Error check If a calculation contains an excessive number of digits, "E" will be displayed and further calculation cannot be made (error check). • Model: PF-8000 • Calculator • Error occurs: Functions: 1. When the integer portion of the intermediate or final result exceeds 10 digits. In this event, the numerical value displayed along with the "E" is the approximate answer with the decimal point shown 10 positions to the left of the actual decimal point. 2.
