Note: • The memory area used for calculation input can hold 79
“steps”. One step is taken up each time you press a number key
or arithmetic operator key (+, -, *, /). A ! or a key
operation does not take up a step, so inputting !W(3'), for
example, takes up only one step. • Whenever you input the 73rd
step of any calculation, the cursor changes from “_” to “k” to let you
know memory is running low.

When the priority of two expressions is the same, the calculation is
performed from left to right.
You can use the colon character (:) to connect two or more

you press =.
Important: If adjusting display contrast does not improve display
readability, it probably means that battery power is low. Replace
the battery.

in calculator memory.
• Use d and e to move the cursor to the location you want.
• Press D to delete the number or function at the current cursor
position.
• Press !D(INS) to change to an insert cursor t. Inputting
something while the insert cursor is on the display inserts the input
at the insert cursor position.

5. Handling Precautions
Note: • Mixing fractions and decimal values in a calculation will cause
the result to be displayed as a decimal value. • Fractions in calculation
results are displayed after being reduced to their lowest terms.
• Dim figures on the display of the calculator indicate that battery
power is low. Continued use of the calculator when the battery
is low can result in improper operation. Replace the battery
as soon as possible when display figures becomes dim. Even
if the calculator is operating normally, replace the battery at
least once every two years. A dead battery can leak, causing
damage to and malfunction of the calculator. Never leave a
dead battery in the calculator.
• The battery that comes with the calculator discharges slightly
during shipment and storage. Because of this, it may require
replacement sooner than the normal expected battery life.
• Do not use an oxyride battery* or any other type of nickel-based
primary battery with this product. Incompatibility between
such batteries and product specifications can result in shorter
battery life and product malfunction.
To switch a calculation result between improper fraction and
mixed fraction format: Press 1$(d/c).
To switch a calculation result between fraction and decimal
format: Press $.
Norm: Selecting one of the two available settings (Norm 1, Norm
2) determines the range in which results will be displayed in non-
exponential format. Outside the specified range, results are displayed
using exponential format.
