Operational Keys
II Clear Key: For clearing all entries and
calculations.
II Clear Indicator Key: For correcting en-
'T tries and double entries.
I aI aII Instruction Keys: Press ac·
cording to calculation expression.
iii a-II Numeral Keys: For entering nu·
'f merals.
I Decimal Point Key: Press at the decimal
point position of the numeral to be entered.
In the case of fractional numerals only, it is
not necessary to press the iii key before the
decimal point. Example: 0.123 Operation:
laElEJ
Before Operation
1. Slide forward the power switch which is sit·
uated on the left side of the Palmtronic.
2. Confirm the position of the battery check-
er. If the need le i is poi nting to ~ the blue
section, it means there is sufficient volt-
age. If the needle points to the red sec-
tion, recharge the battery or replace it with
a new one. Correct results cannot be
obtained with the Palmtronic if it is oper-
ated when the needle is pointing to the
red section -.
3. Press
the IIkey. The "H" in the display '
window will change to "0" and operation
can be started.

How to Operate
1. The keys are operated according to the
calculation express ion.
2.
It is not necessary to press the II key
every time before start i ng the next calcul -
ation because the preceding calculation
result is automatically cleared .
3.
The first operation in constant cal culation
is performed according to the calcu l ation
express ion. From the second operation,
each product or quot i ent is obta ined by
just entering the mult iplier or dividend
and pressing the I key. In the case of
constant multiplicat ion, the first entry
(multiplicand) is the constant, and in the
case of constant division, the second eritry
(divisor) is the constant .
4. Press the GI key when i ncorrect entries or
double entries are made, make new en-
tr ies, and continue the operat i on.
5. When any of the instruction keys l£llD
are pressed by mistake, just repress the
correct instruction key and the operation
can be continued.
6. Calculations containing negative si gns are
possible only in the following cases.
Always press the II key before starting
calculations .
-a ~ b = Operation: III II a Ib II
-a: b = Operation: III II a Ib II
7. When an entry for the 11 th digit is made,
"E" is indicated on the very left side of
(
II
the display window and entries above that
cannot be made.
8. When the integral number part of the reo
suit exceeds 10 digits, an "E" is indicated
on the left side in the display window and,
at the same time, only the top 10 di gits
are indicated. In this case, the decimal
point cannot be seen. However, it is
stored inside. Therefore, this result can
be used as it is in the next multiplication
or division.
9. The disp layed numerals disappear after
awhile and "H" is displayed. Press the I
key to recall a numeral.
After Completion of Calculation
Set the power sw i tch at OFF.
How to Use the NiCd Battery Pack
1. Align the contact side of the battery pack
with the contact , side of the . battery load-
ing section, located on the rear ·. section of
the Pal mtronic, and insert .
2. When removing, pull it out while pushing
the latch of the battery pack .
• When removing the
battery pack, be care-
ful that the contact
section does not come
into contact with any
metallic parts.
How to Use the Exclusive Charger
1. Set the Palmtronic, attached with the bat-
tery pack, on top of the charger, slide it

along the guide rail and connect it to the
insertion slot of the charger. At this time,
keep the power switch of the Palmtronic
set at OFF.
2.
Insert the tightening screw located on the
bottom side of the charger, into the screw
socket of the Palmtronic and turn it
cloc ·kwise until it stops. Make sure it is
securely fixed.
3. Insert the plug of the cord into an AC
power socket . The power indicator lamp
(red) and · the charge lamp (yellow) will light
up to indicate that charging has started.
4. When charging nears completion, the
charge lamp will start to flash on and off.
It will go off when charging is completed.
5. When detaching the Palmtronic from the
charger, loosen the screw on the bottom
side of the charger and pullout the Palm-
tronic along the guide rail, being careful
not to damage the insertion slot.
I
• When the charger is to be used as an
adapter for AC power, it can be operated
by setting the Palmtronic power switch at
ON. If the power switch is set at OFF,
after completion of operation, charging
will be continued.
• There is no fear of overcharging even when
the charger is left connected to an AC
power source.
• When it is necessary to use a power
source with a voltage not indicated on
the rated voltage plate, consu It your
nearest Can.on dealer.
How to Use a Dry Battery Cassette
1. Load a dry battery cassette with four new
penlight (size AA) dry batt~ries. When
loading the batteries, first lay the black
tape, which comes attached with the cas-
sette, on the bottom and then load the
batteries from the minus (-) side accord-
ing to the diagram inside. The Palmtronic
will not function if the direction of the
batteries are incorrect.
2. Load the dry battery cassette into the
battery chamber of the Palmtronic.
3. When changing the dry batteries, take
them out while holding the latch of the
cassette. Change all four batteries at the
same time. The dry batteries can be
easily taken out by pulling the black tape
of the cassette.
