@ Memo In Mode
{cg} — MEMO IN mode
Use this mode to input or edit memos. The symbol [ii{iN} is shown on the display while
the calculator is in this mode. Repeat this operation to leave the MEMO IN mode. See
page 59 for details on the MEMO IN mode.
“When you store data using the MEMO IN mode, the current calculation mode is also
stored along with the data.
3. Reading the Display
@ Symbols and Indicators
When you look at the display of the calculator, you can see various symbols and indica-
tors. These tell you the status and mode of the calculator.

M: Displayed when there is something stored in the independent memory.
((%)): Displayed while the calculator is in the MEMO IN mode. («J only is displayed
when you press the key to perform a search in a calculation mode.
eq: Displayed while you are editing data in the MEMO IN mode
BASE-N: Displayed while the calculator is in the BASE-N mode.
SD: Displayed while the calculator is in the SD mode.
LR: Displayed while the calculator is in the LR mode.
fa: Displayed while degrees are specified as the angle unit.
fa: Displayed while radians are specified as the angle unit.
G: Displayed while grads are specified as the angle unit.
ENG: Displayed while the calculator is in the ENG mode.

hyp: Appears when you press the fi) key.
om: Displayed which an intermediate calculation result is being shown.
DEC: Displayed while decimal input is specified for the BASE-N mode.
HEX: Displayed while hexadecimal input is specified for the BASE-N mode.
BIN: Displayed while binary input is specified for the BASE-N mode.
OcT: Disptayed while octal input is specified for the BASE-N mode.
FIX: Displayed while the number of decimal places is specified.
SCI: Displayed while the number of significant digits is specified.
=<»: indicate that a display exceeds 12 characters. = indicates that the display is
continued off of the left side of the screen while > indicates that it continues
off of the right.

@ Exponential Displays
The display can show calculation results only up to 10 digits long. When an intermediate
value or a final result is longer, the calculator automatically switches over to exponential
notation. Values greater than 9,999,999,999 are always displayed exponentially, while the
lower limit is selectable. Note the following:
Type Lower limit Upper limit
A (Norm 1) 0.01 (107?) 9,999,999,999 (10°°)
B (Norm 2) 0.000000001 (107°) 9,999,999,999 (10'°)
Values less than the lower limits or greater than the upper limit shown above are displayed
using exponential format.
Use the following procedure to switch between the Type A lower limit and the Type B low-
er limit:
(1) Check the display to see if the FIX or SCI symbols are shown, indicating that the num-
ber of significant digits or the number of decimal places have been specified. If either
of the symbols is shown, press {m09(9] to cancel the specification.
(Perform the following calculation:
1 320088
(3) Look at the display to see what the current lower limit is.
If the display reads:
5.~°, the current setting is Type A
If the display reads:
0.005, the current setting is Type B
Press {#0)(8) to switch between the Type A and Type 8 lower limits.
*Note that the lower limit is not changed if you press (09(9) while the number of signifi-
cant digits (SCI disptayed) and/or the number of decimal places (FIX displayed) are speci-
fied. The first time you press (va§(S), you clear the FIX and SCI specifications, and so
you must press (0)(9) again to change the lower limit.
*Notes on Exponential Notation
A value that is expressed exponentially takes up much less space. To convert a positive
value from exponential notation, iook at the exponent for the number 10 in the exponen-
tial notation. Then move the decimal place of the value to the right, the same number
of places, adding zeros as needed. For example:
~6-
