PREFACE
Congratulations on your choice of a Victor electronic
calculator. Careful design, quality materials, painstaking
workmanship, and advanced research and production
facilities have given you a calculator that with proper care,
will provide years of trouble-free service. To assure future
optimum performance, ask your Victor representative about
low cost protection offered by Victor's Extended Guarantee
Protection Program.
This operating manual describes the features and operation
of the Victor 1240-3A. This calculator features the four basic
arithmetic operations, grand total, sigma, percentage,
percent of change, change sign, item count, non-date add
functions, programmable tax rate, back space, and four key
memory functions.
NEW ANTIMICROBIAL PROTECTION
Your Victor calculator has been engineered with an
Antimicrobial agent that protects the calculator against the
growth of microbes and bacteria.
Did you know that viruses can live for up to 72 hours on
common surfaces, such as desks, phones, and calculators?
How do you protect your calculator? Surprisingly, with silver.
This precious metal is a natural germ-fighter, using its ions to
attack microbes. This silver is so safe and effective that it
has been EPA-approved for use in a wide range of
applications. One of those applications is within your own
Victor Antimicrobial calculators. Now you can reduce
microbes on your desktop environment while maximizing
your calculating power.
