WARNING Handling the Secondary Battery
· Never attempt to remove the energy storage cell from the watch. If the energy
storage cell must unavoidably be removed, store it out of the reach of small children
to prevent accidental swallowing.
· If the energy storage cell should happen to be swallowed, consult a physician
immediately and seek medical attention.
WARNING Replacing the Energy Storage Cell
· Although it is not usually necessary to replace the secondary battery, there may be
rare cases in which it becomes necessary due to a problem with the secondary
battery. If it becomes necessary to replace the secondary battery, please have it
replaced promptly.
17. Using the Tachymeter (When Provided)
The tachymeter feature is used to measure traveling speed such as that of an automobile.
In the case of this watch, the average speed can be approximately determined for a
certain distance by measuring how many seconds it takes to travel 1 kilometer
(measuring range: maximum 60 seconds). To determine average speed, start the
chronograph simultaneous to the start of measurement. Stop the chronograph when the
vehicle has traveled 1 kilometer. An approximation of the average speed over that
distance can be determined by the position of the chronograph second hand at that time.
Example:
If it takes 45 seconds to travel 1
kilometer, then the average
speed over that distance is 80
kilometers/hour.
