zeros. STOP indicator will appear.
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, press and hold “F” for
three (3) seconds until SET appears in the bracket on the top row of this display and
UNIT appears flashing above the upper row of digits in the display.
MI or KM will also appear flashing between the middle and lower rows of the display.
Press “A” until the desired unit of measurement (mile or km) appears.
Press “B” and the first digit of the distance value located in the middle row (000.000)
appears flashing. Advance the digit (0-9) by pressing or holding “A” until the desired
value appears. Once set, move to the second digit by pressing “B”. Change the second
digit by pressing “A”.
Continue to set each digit on the distance scale until you have entered the correct
distance. Press “F” to exit the distance setting process. The distance set will appear in
the middle row without any digits flashing.
NOTES:
(1) Should you need to set any particular digit on the distance scale, press “F” until SET
“mile” or “km” appears flashing. Then press “B” until the correct digit appears flashing.
Change the digit(s) by pressing “A”. To exit 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.
Select Recall Up or Down
While the Speed Timer is reset to all zeros, select Memory recall as Ascending (1,
2,3,…300) or Descending (300,299,298…3,2,1) order by pressing “F”. When
Descending is selected the down arrow (▼) will appear. If Ascending is selected, the
down arrow will disappear.
