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

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
register in which you want the value
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.
