IMPORTANT-READ BEFORE USING YOUR CALCULATOR
Your batteries come from the factory uncharged. It is important to
the long life of your batteries to fully charge them before using your
calculator for the first time. Plug it in to charge them.
A full charge takes about 15 hours. Shut the on/off switch off to
charge batteries faster. Don't worry about overcharging your
batteries. If you leave it plugged in for more than 15 hours no harm
will be done, but it is recommended that you do not leave your
calculator plugged into the charger for long periods of time. The
batteries lose their storage capability if not allowed to occasionally
discharge.
LOW BATTERY: DIM DISPLAY OR ERRATIC PRINT
When the display dims or erroneous symbols or dots print, the
batteries need charging. Do not continue to use the calculator
without charging as a totally discharged battery situation should be
avoided for longest use of the batteries. Charge them for 30 minutes
with the power switch off; then, you may use it in the non-print mode
while the batteries finish charging ... about 8 hours of charging
time ... while in use (5 hours of charging time if power switch is
turned off).
Charge
your batteries for the full 15 hours with the on/off switch off
if your batteries are in a totally discharged state.
IMPORTANT:
Do not operate your printing calculator w:lhout paper
because doing so will possibly damage the printing mechanism.
PAPER SIZE: Width 1.5 in. (38mm).
PAPER TYPES: NS038
paper from National Semiconductor or
1 V2 inch thermal paper available at retail stores which is larger in
diameter requiring the larger paper tray. Other paper may damage
your printer.
Your calculator uses specially treated thermal paper. Store paper
in a cool, dark place. Purchase replacement paper where you
bought your calculator or order by mail or phone from:
NSC
MS 10A173

Kifer Road
Sunnyvale,
California 94086
Telephone: [phone]

INSTALLING THE PAPER
1. Remove the plastic paper tray holder from the back of the
calculator. An extra tray to accommodate the larger core size
paper was included in your purchase of your calculator.
2. Be sure that the paper unrolls from the bottom of the roll and
not the top as shown below; otherwise, no printing will occur.
3. Insert the paper into the paper feed path (slot in back of the
calculator). NUdge
the paper tape with your fingertips into the
paper feed path as you press I ii, the paper advance key. Do
this until the paper feeds through. Do not stick long fingernails
into the mechanism.
4. Replace the plastic paper tray. If your replacement paper i:; the
larger core type, use the larger plastic paper tray included with
your calculator.
If the Non Print switch is set at NP, printing will not occur.
NON-PRINT SWITCH
Put
this switch in the NP position to turn off the printer and use
only the display. This feature will
allow you to save paper when you
have no need
for atape.
DECIMAL SWITCH
THE FLOATING DECIMAL SETTING IS FOR MAXIMUM DECIMAL
NUMBERS IN THE ANSWER
Set the decimal
switch at F for afloating decimal. A floating decimal
system automatically puts the decimal behind numbers as you key
them
into the calculator until you press the decimal point key • .
When the •is pressed
the decimal point is fixed at that place and
further numbers keyed into the calculator during that entry are
entered as decimal fractions,
to the right of the decimal point.
Results are printed with as many decimal places
as capacity permits.
Set the decimal at the 2
place setting and results are printed and
rounded
off at two decimal places.
NUMERAL
AND DECIMAL KEYS
The numeral keys are numbered 0
to 9and double zero. The double
zero key, 00 ,is for quick dollars and "no cents" entries or for
entries with many zeros.
The decimal key is pressed whenever a
number being entered
contains adecimal. It is
not necessary to press • after entering a
whole number.
Numbers may be entered
wLth up to 12 digits.
NO

CLEAR ENTRIES, CLEAR ALL CEjc
This key is labeled CE, an abbreviation for clear entry, and C, an
abbreviation for clear all.
Press CE/
C
once directly following a mistaken key depression and
the depression is erased. Pending multiplication or division prob-
lems, the adding machine and the memory are not cleared. Only
the mistaken entry is cleared. No printing occurs. 0is displayed.
Press CE/c twice to clear the entire calculator. OC prints.
ERROR CONDITION: E prints
Press CE/c twice to clear an error condition which occurs when
results exceed 12 whole number digits or when key is pressed
too fast. An arrow appears to indicate the error condition. The keys
will not operate until the error condition is cleared.
ADDING MACHINE KEYS:
+Press to add. Repeated depressions continue to add the same
number which saves time, eliminates re-entry of the same number
when it appears repeatedly. The number being added prints.
Press to subtract the subtrahend or bottom number, as it's
.written in subtraction. The minuend, or top number, is entered on
+ . Repeated depressions of - cause repeat subtraction.

accumulation at any intermediate point.
The non-add, :#, function is performed by pressing '# /S . directly
following a numeral key entry. This function is for printing account
numbers or other identifying numbers on the tape. See second
example that follows.
'Pressing S or T clears any pending multiplication or division
unless the S or T depression directly precedes = . Division
problems are inverted under certain circumstances in which division
is combined with the use of these keys. See Section INVALID KEY
SEQUENCES WHICH INVERT DIVISION.

The characteristic of your calculator which allows you to perform
percentage
of increase and decrease as shown above results in
invalid key sequences when performing mixed calculations which
do not require inversion of the dividend and divisor.
REMEMBER THIS RULE: You may mix
addition/subtraction with
two factor multiplication but not with division. ENTRIES ON +
