Setting NORMAL TIME and ALARM TIME
While in NORMAL TIME mode, press and hold “F” for 2-3 seconds. “SET” indicator appears. Alarm
hours will begin flashing. Advance Alarm Hours by pressing or holding “C”. After setting Alarm Hours,
Press “E”. Alarm Minutes will appear flashing. Advance by pressing or holding “C”.
Repeat the setting process for Seconds >>>> Hours >>>> Minutes >>>> Month >>>> Date >>>> Day of
the Week >>>> 12/24 Hour Option >>>> and back to Alarm Hours.
Pressing “F” at any time, will automatically exit the setting procedure. “SET” indicator disappears.
Time of Day and Alarm Time will both be presented in the AM/PM or 24 Hour format chosen. “A” or “P”
will appear in the AM/PM format.
Using the Daily Alarm and Hourly Chime
The Alarm can be armed (set to go off) to sound once per day. The Alarm symbol ((((•)))) will appear
when the alarm is armed.
The Hourly Chime can be armed to sound one (1) beep at the top of each hour. The Chime indicator (♠ )
will appear when the chime is armed.
While your SC-554 is in NORMAL TIME mode, press “C” to arm, or disarm your alarm and chime. The
sequence is:
(1) Alarm ON, Chime OFF
(2) Chime ON, Alarm OFF
(3) Alarm ON, Chime ON
(4) Alarm OFF, Chime OFF
When armed, the alarm will sound when the Alarm Time coincides with Time of Day. You may silence
the alarm by pressing any pushbutton.
PART III
CHRONOGRAPH MODE (Stopwatch)
The SC-554’s chronograph is a digital stopwatch with 1/100 second resolution, which will present timing
in any of three (3) different options.
From NORMAL TIME, press “E” once to enter the CHRONOGRAPH mode. Chrono indicator “CHR”
and all zeros should appear. If the display does not show all zeros, reset the chrono by:
If RUN appears, press “A” to STOP and “B” to RESET.
If STOP appears, simply press “B” to RESET to all zeros.
“LAP” Chrono will display the Interval of time from your previous readings. Each time a reading is taken,
the timer begins from zero.
“SPLIT” Chrono will display the Accumulation of time from the start of the event. Each time a reading is
taken, the timer shows the Total amount of time accrued.
“LAP/SPLIT” Chrono will display the Lap Time in the upper row and the Split Time in the lower row of
the display.

How to Determine and Enter the Distance
The first step is to enter the distance correctly.
The SPEED TIMER will not operate unless a distance is entered.
Distance is entered as the decimal equivalent of a mile or kilometer from 000.001 to 999.999. For
example, enter 2 ½ miles or kilometers as 002.500, 1/3 as 000.333, 1/8 as 000.125, etc. (To calculate the
decimal equivalent of a fraction, simply divide the numerator by the denominator . . . for ¾, 3 divided by 4
is 000.750.) Some common distances in decimal form are:
1/10 = 0.100
3/8 = 0.375
1/8 = 0.125
1/2 = 0.500
1/6 = 0.167
5/8 = 0.625
1/4 = 0.250
2/3 = 0.667
1/3 = 0.333
3/4 = 0.750
You may convert feet to the decimal equivalent of a mile, i.e. 187 feet is entered as 000.035 (187 divided
by 5280 feet (1 mile) = 0.035). Some commonly used distances reported by feet are:
Water Ski Slalom Course:
Pitcher’s Mound/Baseball:
Pitcher’s Mound/Youth:
Pitcher’s Mound/Softball:
850 feet = 0.161 mile
60.5 feet = 0.011 mile
47 feet = 0.009 mile
45/47 feet = -.009 mile
Convert meters to kilometers by dividing by 1000. For example, 230 meters is entered as 0.230 km. (230
divided by 1000).
Entering the Distance
The SC-554 can accommodate distances between 000.001 and 999.999 mile/kilometer.
After determining the distance, press and hold “F” for three (3) seconds, “SET” and “DIST” appear. The
“MILE” or “KM” indicator will appear flashing. Press “C” to select between miles or kilometers. Then
press “E”.
The hundreds of miles digit appears flashing. Advance the hundreds of miles digit while flashing by
pressing or holding “C”.
Repeat pressing “F” to select and “C” to advance for tens, units, tenths, hundredths and thousandths. Exit
the setting sequence at any time by pressing “E”. “SET” and “DIST” indicators disappear.
Please note:
(1) The SC-554 returns to the reset position if no pushbuttons are pressed within 15 seconds.
(2) If hundreds and tens digits have no value entered, they will disappear after you have entered the
distance.

Stroke Rate Calculation
You may calculate stroke rate based on one, two or three stroke cycles. Since we are not interested in
MPH/KPH, we will disregard those indicators.
Following the instructions in the “Enter Distance” section, please enter the following values for their
respective stroke cycles:
One (1) stroke cycle . . . please enter 0.017
Two (2) stroke cycles . . . please enter 0.034
Three (3) stroke cycles . . . please enter 0.050
To measure stroke rate, simply START the timer by pressing “A” at the beginning of the cycle and STOP
the timer by pressing “A” again at the completion of the cycle. The number displayed in the upper row of
the display is the Stroke Cycle Rate per Minute.
Take as many readings as necessary. The Average and Fastest rates can be displayed by pressing “F”.
OPERATING THE SPEED TIMER
MEMORY RECALL DIRECTION
Select between ascending “UP” or descending “DN” memory recall direction by pressing “D” while the
Speed Timer is in the reset position.
The recall direction cannot be selected while the Speed Timer is running or not in the reset position.
(1) For Single Lap Events: Press “A” to start. “RUN” indicator appears. Press “A” again to stop the
timer. “STOP” indicator appears. The speed will appear in the right side of the upper row of the
display and the time will appear in the lower row of the display.
Press “B” to reset to all zeros.
(2) For Multiple Lap Events: Press “A to start, “RUN” indicator appears. Press “B” to take Lap readings.
Lap Time will appear in the lower row of the display, Lap Speed in the upper row and Lap Number in
the Lap Counter. Continue to press “B” to take as many lap readings as necessary. The SC-554 will
record up to 999 laps.

“C”.

After pressing “B”, should “ERROR” appear in the upper row, followed by five (5) beeps, you have
exceeded the timer’s measuring capability of 1000 mph/kph. When this occurs, the Lap Time continues to
run. To correct the error, simply press “C” to return to the previously recorded lap. Then press “B” to take
the appropriate lap readings.
Upon completion of the event, or to stop the Speed Timer at any time, press “A”. “STOP” indicator
appears and one (1) is added to the Lap Counter.
Then, press “B” once, to display the accumulated time and again to reset to all zeros.
AVERAGE, MAXIMUM and MEMORY Functions
The MAXIMUM SPEED/FASTEST LAP reading can be displayed at any time, by pressing “D”. The
“MAX” indicator will appear, as will the lap number, speed and time of the fastest lap. To return to any
previous function, press “C” or the SC-554 will automatically do so after 15 seconds.
The AVERAGE SPEED and TIME of multiple laps, up to 999, can be computed and displayed at any time,
by pressing “D”, again. “AVG” indicator appears and the average lap time will appear in the upper row of
the display, along with the total number of laps completed.
30 MEMORY RECALL of lap speed, time and number can be displayed at any time, up through 999 laps,
by pressing “F”. Recall “RCL” indicator appears. Holding “F” down, will cause the previous readings to
be displayed at a rate of one per second.
If the “RUN” indicator appears, you may take another Speed reading at any time, by pressing “B”. You
may also instantly return to the last previous reading at any time by pressing “C”.
The memory recall operation will review previous readings in ascending “UP” or descending “DN” order,
depending on the option selected.
NOTES:
(1) The SPEED TIMER will not operate unless a distance has been entered.
(2) The SC-554 will measure up to 24 hours or 999 laps.
