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 speed chronometer will compute and display speed in MPH/KPH as a function of distance and time.

To enter the speed mode from normal time, press (E) once. If the speed timer is running, stop timing by pressing (A) once. Reset the display to all zeros by pressing (B).

The display appears as follows:

How to determine and enter the distance

The first step is to enter the distance correctly. The speed timer will not work 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/kilometers as 002.500, 1/3 as 000.333, 1/8 as 000.125, etc.


You may convert feet to the decimal equivalent of a mile, i.e., 187 feet is entered as 000.035 (187 divided by 5280 = 000.035).


Convert meters to kilometers as follows:  230 meters is entered as 000.230 (230 divided by 1000 = 000.230).

Enter distance

To enter the distance when the timer is stopped and reset to zeros, proceed as follows:


(1)  Press and hold (F) for three (3) seconds until “MILE” or “KM” appears flashing above the upper row of digits in the display. Press (C) until the desired unit of measurement (mile or km) appears.

(2)  Press (E) and the first digit of the distance scale  (Row 2) 000.000 appears flashing. Advance the digit (0-9) by pressing or holding (C) until the desired digit appears. Once set, move to the second digit by pressing (E) once. Change the second digit by pressing (C).

Continue to set each digit on the distance scale until you have entered the correct distance. Press (F) to end the distance setting process. The distance set will appear and no digits will be flashing.

The illustration shows as distance of 2 ½ (2.500) miles entered.


(1)  Should you need to set any particular digit on the distance scale, press (F) until “MILE” or “KM” appears flashing. Then press (E)  until the correct digit appears flashing. Change the digit(s) by pressing (C). To end the setting procedure, press (F).

(2)  The maximum setting distance is 999.999 miles or kilometers.

(3)  The speed timer will not work unless a distance has been entered.

Under normal use, the battery in the SC-808 (Lithium type CR2032, or equivalent) will power your stopwatch for 1 1/2 - 2 years. Excessive use of the EL backlight could significantly shorten this battery life.
