Replacing the Batteries
Replacing the Batteries
The “ ” icon appears on the display when the batteries go low. Replace the
batteries as soon as possible after this icon appears.
•If you continue using the calculator while the batteries are low, you run the risk of
losing data in calculator memory whenever light to the solar cell is cut off momentarily.
You should replace the batteries at least once a year, even if the “ ” icon does
not appear.
■Important! Read this before replacing batteries!
•Replace both batteries with new ones.
•Be sure to use AAA-size alkaline batteries only. The life of manganese batteries is
very short when used to power this calculator, and their use can cause malfunction.

■Sales Tax Calculation (Rate = 5%)
Example 1: For an item with a pretax price of $ 100
What is the price plus tax?
What is the tax amount?
Example 2: For an item with a price of $ 105, tax included
What is the pretax price?
What is the tax amount?
•Pressing the ( ) key toggles the displayed value between the with tax
amount ($ 105 in Example 1) or without tax amount ($ 100 in Example 2), and the
tax amount (5).
•Cutting or rounding of the decimal part is performed automatically in accordance
with the setting of the rounding selector (F, 5/4, etc.) and decimal places selector
(4, 3, etc.) During internal calculations the calculator first obtains the tax amount in
accordance with the selector settings, and then calculates the tax included (without
tax) amount in accordance with the selector settings.
Example 3: What would be the amount due, including tax, for three items
with prices of $ 300 excluding tax, $ 700 including tax, and $ 2,000 including
tax?
Operation: First calculate the amount due for the items that does not include tax.
