Tax Rate Setting Precaution
Replacing the battery or blocking the calculator from sunlight while battery
power is low may cause your tax rate setting or memory contents to be
changed or lost. Replace the battery as soon as possible when it becomes
weak and correct the tax rate setting, if necessary.

Always be sure to check the tax rate setting
before starting tax calculation.
