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.

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.
