© The stopwatch features a 40-minute dial with a retrograde minute hand © The stopwatch can consecutively measure up to 120 minutes in 1/100-second increments. When the measurement reaches 120 minutes, the stopwatch auto- matically stops counting © Split time measurement is possible. © After 3 minutes of timing from a start, the STOPWATCH 1/100-second and 1/10- second hands remain pointing to the “0” position until the watch is stopped or split time measurement is made, at such a time, they move to display the measured time. They start to move for a maximum of three minutes after the watch is restarted or the split time display is released. <How to read the stopwatch hands> The time measured is indicated by the four stopwatch hands below. STOPWATCH 1/100-second hand STOPWATCH 1/10-second hand STOPWATCH second hand STOPWATCH minute hand Reading the 1/100-second and 1/10-second hands requires extra attention The display ilustrated at the left should be read as “19,” not "29." When the 1/100-second hand is moving toward larger numbers, the 1/10 second hand comes close to the next marker, which may cause you to wrongly read the hands as “29. <Remarks on the STOPWATCH minute hand movement> When the minute counting reaches 40 minutes, the STOPWATCH minute hand immediately returns and continues counting from 41 minutes onward. The minute counting is repeated in the same manner for another rotation, up to 120 minutes, at that time the stopwatch automatically stops. The final position of the STOPWATCH minute hand, after completing 120 minutes of counting, is illustrated below. Before starting to use the stopwatch again, make sure to reset the stopwatch by pressing Button B. ys18ux

TACHYMETER (for models with tachymeter scale on the dial) RER (1) STOPWATCH second hand: 40 seconds I Use the stopwatch to determine how many seconds it takes to go 1 km or 1 mile.

Tachymeter scale: 780! “90” (tachymeler scale figure) x 1 (km or mile) 0 km/h or mph © Tachymeter scale can be used only when the time required is less than 60 seconds.

For example, it can indicate the distance to the place where lightning struck by measuring the time elapsed after you see a flash of lightning until you hear the sound. © _A flash of lightning reaches you almost immediately while the sound travels to you at a speed of 0.33 km/second. The distance to the source of the light and sound can be calculated on the basis of this difference. © The telemeter scale is so graduated that the sound travels at a speed of 1 kmin 3 seconds.*

• Under the condition of temperature of 20 °C (68 ‘Fi. À CAUTION The telemeter provides only a rough indication of the distance to the place where lightning struck, and therefore, the indication cannot be used as the guideline to avoid the danger of lightning. It should also be noted that the speed of the sound differs depending on the temperature of the atmosphere where it travels. usBuT
