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

1/8 = 0.125

1/6 = 0.167

1/4 = 0.250

1/3 = 0.333

3/8 = 0.375

1/2 = 0.500

5/8 = 0.625

2/3 = 0.667

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:

850 feet = 0.161 mile

Pitcher’s Mound/Baseball:

60.5 feet = 0.011 mile

Pitcher’s Mound/Youth:

47 feet = 0.009 mile

Pitcher’s Mound/Softball:

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.
