[. . . ] cALENDAR Date in displayed in numerals. ALARM The alarm is set on a 12-hour basis with 2 small hands displaying the designated alarm time. sTOPWATCH It can measure up to 30 minutes. BATTERY LIFE INDICATOR The continuous second small hand moves at two-second intervals when the battery needs to be replaced. [. . . ] However, if crown "2" is pushed back in to the normal position before the beep stops, the designated alarm time will not be canceled. The stopwatch can measure up to 30 minutes at 1 second intervals. After 30 minutes, it will start counting again from "0" repeatedly up to 6 hours. * Before using the stopwatch, be sure to check that crowns "1" and "2" are set at the normal position, and press "B" to reset the stopwatch hands to "0" position. Split (intermediate) time measurement T start o T measure split time o T release split time o * Measurement and release of the split time can be repeated by pressing "B". Measurement of two competitors T start o T measure the finish time of the first competitor o When the second competitor finishes T measure the finish time of the second competitor o T reset o : Press : Press : Press : Press : Press : Press : Press : Press : Press : Press Notes on crown operation while the stopwatch is in use Crown "1": Even if crown "1" is pulled out to the first click, the stopwatch continues measuring. However, if it is pulled out to the second click, the stopwatch hands are reset to "0" position. Crown "2": If crown "2" is pulled out to the first or second click, the stopwatch hands are reset to "0" position. Is pressed before the hand reaches "0" * When the stopwatch has been reset and position, the stopwatch still starts counting time when is pressed. Stopwatch operation (Standard measurement) Press : T start o : Press T stop o : Press T reset o The tachymeter can be used for the following purposes. Use the stopwatch to determine how many seconds it takes to go one kilometer (or one mile). The tachymeter scale indicated by the stopwatch second hand gives the average speed per hour. * Please note that the tachymeter scale can be used only when the time required is less than 60 seconds. : 1) If it takes 40 seconds to go one kilometer (or one mile), the stopwatch second hand indicates "90" on the tachymeter scale. This means that the average speed of the vehicle is 90 kilometers (or miles) per hour. 90 T achymeter scale figure at 40 seconds position x 1 (km or mile) , 90 T achymeter x2 scale figure (Kilometers at 40 seconds position or miles) 90 T achymeter x 0, 5 scale figure (Kilometers at 40 seconds position or miles) 30 20 10 If it takes 20 seconds, the stopwatch second hand indicates "180" on the tachymeter scale. : 2) Use the stopwatch to determine how many jobs are accomplished in a specific period of time. If 15 jobs are completed in 20 seconds, multiply "180", the figure on the tachymeter scale indicated by the stopwatch second hand, by 15. thus , it is estimated that 2 , 700 jobs will be accomplished in one hour. T achymeter scale figure at 20 seconds position T achymeter scale figure at 20 seconds position If the stopwatch hands and will not return to the 12 o'clock position when the stopwatch is reset or when the battery is replaced with a new one, follow the procedure below to reset the hands to the 12 o'clock position. Pull out crown "1" to the second click. Press and repeatedly but separately to reset the stopwatch hands to the 12 o'clock position, respectively. [. . . ] Pay special attention to avoiding contact with chemicals. The watch case and strap may discolour if they come into contact with mercury from a broken thermometer or other equipment. Keeping the watch clean Use an absorbent soft cloth to clean off any dirt or damp from the watch glass. Wearing the watch when the strap or back of the case is dirty can cause skin irritation.
