SOUNDESIGN 8309-232 User manual

The Soundesign calculator, you have just purchased, contains many of the most advanced engineering concepts.
presently found in small portable calculators.
Using a large Scale Integrated (lSI) circuit, the calculator performs addition, subtraction, multiplication, and
division operations, as well as chain, constant, percentage, reciprocal, power and memory calculations insta-
ntly and with the utmost accuracy and reliability.
Please take a few minutes now to read this Instruction Book.
it will make operation of your calculator easy and accurate.
SPECIAL FEATURES
• long Battery life
Uses long. lasting, inexpensive "C" cell battefles. Unneeded zeroes are not
displayed to conserve power.
t
( • Clear & Clear Entry Key Permits correction of entry mistakes without having to repeat entire opera-
tion.
• Double Entry Proof
• AC Adaptor Jack
If two keys are pressed accidentally, only the first number will be entere,d and
displayed.
Unit is equipped with an AC adaptor jack for use on AC to save batteries.
Use optional AC adaptor model 232.

OPERATING INSTRUCTIONS
BATTERY INSTALLATION
1. Slide battery compartment cover out in the direction shown by the arrow.
2.
Place four 1.5V "c" size batteries in the compartment as shown on the diagram in the compartment.
Make certain batteries are properly orientated with correct positive-negative arrangement.
CAUTION: Improper arrangement of the battery terminals will result in damage to your calculator.
AC OPERATION
If your unit is equipped with AC Adaptor Model 232, you may operate the calculator on AC current. Insert
the AC Adaptor plug into the receptacle marked EXT POWER on the side of the unit. To operate the calcu-
lator on battery (DC) power, simply disconnect the AC AdaPtor plug from the calculator.
,-
CAUTION: Only AC Adaptor Model NO.232 should be used with this calculator. Use of other adaptors will
cause serious damage to the unit.
CONTROLS
Power ON-OFF Switch (Fig. 1. 3); Turn your calculater on by sliding the Power Switch to the ON position.
To turn the calculator off, slide the switch to the OFF position. Make certain to turn off the calculator when
you are not using it. This will provide maximum battery life.
Number Entry Keys (Fig. 1. 4)
These keys are used to enter numbers. Your calculator is double entry proof. If you press two numbers at
the same time, only one will be entered and displayed. If you enter the wrong number, press the C(Clear &
Clear Entry) key and re-enter the correct number.

be after the I ast digit entered.
Stores an addition command and performs any possible proceding operation.
Stores a subtraction command performs any possible preceding operation.
Stores a multiplication command and performs any possible preceding operati on.
Stores a division command and performs any possible preceding operation.

Performs preceding operation, divides the result by 100 and leaves results in the Display Register.
The number in the Display Register is added to the Memory Register. The contents of the Display
Register remain uncharged.

Memory Register.
Clears a
complete operation when this key is depressed twice.
Clears only the last entry when this key is depressed once.
Simply re-enter the correct number and proceed with the operation.
Display
The minus sign is displayed immediately preceding the number.
If a negative number contains eight digits, the minus sign will be displayed in the special information display
position.
Overflow indication are always displayed in the most-significant display of answer.
Constant Operation
The calculator provides for automatic constant operation for add, subtract, multiply and divide. No constant
mode switch is necessary, For addition, subtraction and division the number entered following the 8-J 8. or
EJ key is the constant factor. For multiplication. the number preceding the 0 key is the constant. In the
case of constant operations with only one number. as with raising to a power or reciprocal, the entered
number becomes the constant.

Memory
The IMel key clears the contents of the Memory Register. leaving the contents of the Display Register un-
changed. The jM+ I key cause the contents of the Display Register to be added to the contents of the mem-
ory, leaving the Display Register unchanged and any pending commands unaffected.
Overflow
The Model 8309 has the capability of providing a meaningful displayed result when overflow occurs during
computation. Overflow occurs when the result exceeds eight digits which causes the 8 most-significant digits
of the result to be displayed divided by 10
8
(decimal point moved 8 digit positions to the left). This occur-
rence provides an overflow, or 10
8
indication (C ) to be displayed in the special information display position.
The overflow indication inhibits further calculation_ The overflow is cleared by depression of the [g once_
This operation removes the overflow indication only and retains the result in the Display Register. Continued
calculations can be performed using this result. noting that the results should be mUltiplied by 10
8
factor.
