Basic Calculator Information

Power On/Off

The ScheduleCalc is powered on by

pressing the [On/C] key and powered

off by pressing the [Off] key. If already

on, a single press of [On/C] clears the

last entry. A double press clears all

temporary values.

Automatic Shut-off

If left on more than eight minutes with-

out activity, the auto-save feature shuts

the calculator off. When this occurs, all

values stored in Memory or shown on

the display are cleared. An activated

timer/stopwatch disables the automatic

shut-off.

Full Reset/All Clear

Your calculator is programmed with a

special two-key sequence, [Conv] [x].

This key sequence clears all Memory

registers and resets the calculator to its

default state.

Operating Fundamentals

4—ScheduleCalc™

Display Accuracy

ScheduleCalc has a 10-digit internal

accuracy with a 5/4 rounding technique

for an accurate 8-digit display.

Battery Information

Your calculator is powered by a single

3 volt Lithium CR-2032 battery. This

should last upwards of 800 hours of

actual use (1 year plus for most people).

Should the display become dim or

erratic, replace the battery.

WARNING

Because the batteries contain hazardous

chemicals, please use caution when dispos-

ing of old batteries. Keep them away from

animals and young children.

Basic Math

ScheduleCalc uses standard “chaining

logic.” In other words, calculations are

processed in the order entered.

3 [+] 2 [=] 5

3 [–] 2 [=] 1

3 [x] 2 [=] 6

3 [÷] 2 [=] 1.5

Owner’s Manual—5

Percent Calculations

[ % ]

The percent key is used for finding a

given percentage of a number or for

working add-on, discount or division

percentage calculations.

355 [x] 15 [%] 53.25

250 [+] 6.5 [%] 266.25

25 [–] 5 [%] 23.75

100 [÷] 50 [%] 200

Delta Percent

[Conv] [ % ]

The Delta Percent function finds the

percent change between two values.

The [=] key must be pressed to com-

plete the calculation.

10 [Conv] [%] 15 [=] 50.

100 [Conv] [%] 25 [=] – 75.

6—ScheduleCalc™

Memory Functions

The ScheduleCalc allows you to store,

add, subtract, replace and recall up to 10

separate Memory values. Memory values

do not change unless revised or the

calculator is reset to its default state.

Values can be stored in any format.

Note: Memories 1–9 store a single value,

while Memory “0” maintains a cumulative

total. When adding to Memory “0,” only

values of the same convention (i.e., hour,

minute, second, day, week, month or year),

may be added. Otherwise, enter values but,

no format.

[Stor] [0] through [9]

Enters and stores a value in Memory

registers 0–9. Press [Stor], then the

number key representing the Memory

stored.

[Rcl] [0] through [9]

Recalls values stored in Memories 0–9.

[0] [Stor] [1] through [9]

Clears the value from the Memory reg-

ister coinciding with the number key

(1–9) pressed.

Owner’s Manual—7

[Conv] [+]

Clears Memory registers 0 through 9.

[Conv] [Stor] [0]

Subtracts the displayed value from

Memory “0.”

[Rcl] [Rcl]

Displays then clears Memory “0.”

[Conv] [Rcl]

Clears Memory “0” without changing

the display.

Calendar Mode Settings

The [Mode] key is used to select the

Day Count method used when doing

date math calculations. Calendar Mode

setting options are discussed below:

Setting Options

CAL Act: Act

Uses the actual number of days in a

month and year (including leap year)

when calculating date math problems.

WORK Act: Act

Counts only the workdays in a month.

The

“Monday–Sunday”

preference set-

tings determine the number of work

days per week. This method takes into

consideration the hours per day and

any stored holidays.

CAL 30: 360

Defines the year as 12 months of equal

value: 30 days each.

CAL Act: 365

Based on 365 days in a year, this

method does not include the extra day

in a leap year.

Owner’s Manual—13

CAL Act: 360

This method counts a year as 360 days.

The monthly count is based on the

actual number of days in the month.

Changing the Mode Setting

1. Move through the options by

repeatedly pressing

[Mode].

2. Display the option you want to set

then move to the next option or if

Time and Date Math Rules

There are basically two kinds of time

and date conventions considered:

1. Points in Time (a specific time or date):

9:22 AM, 5 PM

1/15/1997

2. Time Periods (a span of time):

37 Minutes, 45 Seconds

2 Weeks, 3 Days

Tme and date formats are Hours,

Minutes, Seconds, Years, Months,

Weeks, and Days. When entering Time

and Date values, the entry must comply

with the following rules:

Addition

Period + Period = Period

Point + Period = Point

Point + Point = Error

Subtraction

Period – Period = Period

Point – Period = Point

Point – Point = Period

Period – Point = Error

Note: When subtracting one point in time

from another, enter the later time first, then

the earlier time.

16—ScheduleCalc™

Multiplication

Period x Period = Error

Point x Period = Error

Point x Point = Error

Period x Number = Period

Point x Number = Error

Division

Period ÷ Period = Number

Period ÷ Number = Period

Period ÷ Point = Error

Point ÷ Period = Error

Point ÷ Number = Error

Point ÷ Point = Error

Owner’s Manual—17

Important Note!

Unless otherwise indicated, all sample prob-

lems in this section assume the ScheduleCalc

is in its default state. If not, use [Conv] [x]

to reset the calculator.

Time Values

If the “SECS” preference setting is “ON”,

the display shows a place holder (00)

for seconds even if the [Sec] key was

not used.

If set to “OFF”, you must press the [Sec]

key to display the seconds placeholder.

If entering points in time, it is not nec-

essary to use the [:] key. See

Method 5

for an alternate method.

When entering time values, you may use

any of the following entry methods.

However, remember to always enter

hours first, then minutes, then seconds.

Note: In the following examples, the first

value shown is with the “

SECS

” setting

“

OFF

.” The second value is with the “

SECS

”

setting “

Date Values

When entering dates, the full year should

be entered to avoid mis-interpretation. If a

year is not entered, the calculator uses the

year setting (viewed by pressing [Rcl]

[//] ), which defaults to the year 2000.

If entering only the last two digits of a

year, digits 00–59 are interpreted as

2000–2059; digits 60–99 as 1960–1999.

Entering Date Values
