1. Key and Controls Numeral Keys/Decimal Point Key: For entering numbers. Addition and Subtraction Keys Subtotal Key: For obtaining intermediate results of addition and subtraction and the number of items (the number of times the “+” or “–“ keys have been pressed).
Percent Plus/Minus Key: For performing percentage add-on and discount cal- culations. Memory Plus/Equal Key: For obtaining a calculation result and adding the result automatically to the memory. This key is also used to add a number to the memory. Memory Minus/Equal Key: For obtaining a calculation result and subtracting the result automatically from the memory.
Power On/Paper Feed Key: Used to feed the paper when the power switch is on, and also used to reactivate the display if the Automatic Power Off Function (see p.6) turns the calculator off. Decimal Point Selector Switch: For designating the decimal point position for calculation results.
When printing is not required (i.e. the printer switch is OFF), the calculator can be used as an ordinary display model. Input Buffer Register Function: The buffer register allows all numbers, basic function and other function keys to be depressed while numbers are being printed. The calculator remembers up to 9 key entries in the register, and calculates them in the sequence entered.
2) Remove the old ink roller by inserting the tip of a pen or other pointed object to the right of the retainer pin and lifting the roller out. 3) Set a new Canon CP-12 ink roller into position. 4) Replace the printer cover.
3. How to Insert Printing Paper 1) The edge of the paper should be positioned as shown in figure (1). 2) Lift the paper deflection hook and insert the edge of the paper into the slit as far as possible. 3) Turn the power switch ON.
Replacement Low battery voltage may cause printing defects, random paper advances or the inability of the “C” key to clear the overflow. Printer Error Lock When the printer is on, low battery voltage may cause printer error lock. In this case, depress the “C”...
Loading 1) Remove the cover of the battery chamber on the bottom of the P20-DX by sliding it in the direction of the arrow. 2) Load four new penlight batteries (size AA) into the battery chamber as illustrated, by inserting the (-) end first.
5. Canon AC Adapter AD-11 1) Use only the Canon AC Adapter AD-11 with the P20-DX. 2) Turn the Power Switch of the calculator OFF before connecting or disconnecting the AC Adapter. 6. Overflow Interlock Function “E” lights up on the display and a dash line is printed in the following overflow cases: 1.
Example 1: Overflow of addition and subtraction Operation Display Printout 9999999999 + 9999999999 99999999999 + 0099999999 + 99999999999 + E1.999999999 ------------------- 19999999998 * Example 2: Overflow of multiplication and division Operation Display Printout 12345 X 12345. 12345 x 56789 X 701060205.
2, When dividing by “0”. 3. Buffer Register Overflow When the sequential operation is made using more than 9 keys; depress the “CE” key or the “C” key to clear the overflow. 4. If the batteries are weak, the “CE” or “C” key may not unlock the keyboard. In this case, change all four batteries at the same time, or use the AC Adapter AD-11.
