Features
Your Nexxtech 12-Digit Dual Power
Metal Top Desk Calculator can be
powered from two different sources,
so you can use it almost anywhere.
Its built-in solar panel provides power
when you expose the calculator to
light. When there is not enough light,
the supplied battery provides power.

display shows the selected number of
digits to the right of the decimal point.
With the switch set to F (full display),
the display shows as many numbers
to the right of the decimal point as

CALCULATION ERRORS
• You attempt to divide by 0.
• You attempt to calculate the
square root of a negative num
ber.
If an overflow error occurs, E appears. To clear E from the display
(without deleting numbers from mem
ory), press CE.
If the error occurs in a memory calculation, M (memory) flashes and E appears. To clear E from the display,

Estimating Calculation Results
If your calculation results in an overflow error, you can estimate the approximate result by following these
steps.
E (error) appears on the display
when:
• A calculation result exceeds 12
digits (this is an overflow error —
“Estimating Calculation
see
Results”).
• A memory calculation exceeds
12 digits.
Operation
1. Count the number of digits displayed to the left of the decimal
point.
2. Remove the decimal point.
3. Add as many zeros to the right of the number as there were digits to the left of the decimal point.

Mark-Up Calculations

item’s selling price based on the cost
and the desired gross profit margin,
and also lets you calculate the gross
profit margin based on the cost and
sales price.

CONSTANTS
Example 3:
When adding, subtracting, or dividing,
the last operation and number you
enter are held in memory as the con
stant function, allowing easy calculations with repetitive numbers. Each
time you press
=, the calculator per-
forms the constant function and displays the results.
Example 1:
5 + 6 = 11
You Press You S e e
4 + 6 = GT 10.
5 = GT 11.
(+6 is the constant)
Example 2:
14 – 7 = 7
You Press You S e e
14 ÷ 7 = 2
You P r e ss You S e e
21 ÷ 7 = GT 3.
14 = GT 2.
(÷7 is the constant)
When multiplying, the first operation
and number you enter are the con
stant function. For example:
4 × 5 = 20
You P r e ss You S e e
4 × 6 = GT 24.
5 = GT 20.
(4 × is the constant)
-
20 – 7 = GT 13.
14 = GT 7.
(–7 is the constant)

Care
Your Nexxtech 12-Digit Dual Power
Metal Top Desk Calculator is an ex
ample of superior design and craftsmanship. The following suggestions
will help you care for your calculator
so you can enjoy it for years.
• Keep the calculator dry. If it gets
wet, wipe it dry immediately. Liq
uids might contain minerals that
can corrode the electronic cir
cuits.
• Use and store the calculator only
in normal temperature environ
ments. Temperature extremes
can shorten the life of electronic
devices, damage the battery, and
distort or melt plastic parts.
• Keep the calculator away from
dust and dirt, which can cause
premature wear of parts.
• Handle the calculator gently and
carefully. Dropping it can dam
age circuit boards and cases and
can cause the calculator to work
improperly.
• Use only a fresh battery of the
required size and type. Batteries
can leak chemicals that damage
your calculator’s electronic parts.
• Wipe the calculator with a damp
cloth occasionally to keep it look
ing new. Do not use harsh chem-
icals, cleaning solvents, or strong
-
-
-
detergents to clean the calcula
tor.
Modifying or tampering with the calculator’s internal components can
cause a malfunction and invalidate
the calculator’s warranty. If the calcu
lator is not performing as it should,
take it to your local electronic store for
assistance.
REPLACING THE BATTERY
-
Although your calculator is solar powered most of the time, the supplied
back-up battery might eventually
weaken and need replacing. If the
display speed slows down in low light,
replace the 389A battery. For the best
performance and longest life, we rec
ommend alkaline batteries.
Warnings:
-
• Keep button-cell batteries away
from children. Swallowing a but
ton-cell battery can be fatal.
• Dispose of an old battery
promptly and properly. Do not
burn or bury it.
Caution: Use only a fresh battery of
the required size and recommended
type.

back of the calculator, then pull
apart the front and back case
halves.
2. Slide the battery toward the open end of the holder to remove it.
5. Reinsert and tighten the screws.
If you do not plan to use the calculator
for a long period of time, remove the
battery. Batteries can leak chemicals
that can destroy electronic parts.
3. Insert the new battery with the positive (+) side facing up.
