[. . . ] A C B English Make Sure the Watch is Sufficiently Charged Before Use Check that the second hand of the watch is moving correctly in 1-second interval movement before use. If the second hand is moving in 2-second interval movement or is stopped, this indicates that the watch is not fully charged. When this happens, expose the solar cell to light to recharge or recharge the watch by swinging. When exposing the watch to light, do not place the watch too close to the light source. [. . . ] * The watch should be swung approximately 200-300 times to ensure 1 full day's worth of charging when running normally (1-second interval movement). * Charging can be performed even more efficiently by combining charging by exposing the watch to light and charging by swinging. * Since this watch is provided with an overcharging prevention feature, there is no risk of damage to the watch due to excess charging. 7. Warning Features When this watch becomes undercharged, a warning feature is activated and the display of the watch changes. <Insufficient Charging Warning Feature> When the second hand is moving in 2 second intervals (moving once every 2 seconds), this means that the watch is undercharged. Although the watch will continue to run normally at this time, the watch will stop if 2-second interval movement is allowed to continue for roughly 1 day. When this happens, charge the watch by referring to Section 6 entitled, "Charging Procedure" so that it returns to normal 1-second interval movement. Furthermore, the chronograph function cannot be used when the insufficient charging warning feature has been 45 activated (during 2-second interval movement). * If charging is only performed until the watch returns to 1-second interval movement, it will again return to 2-second inter30 val movement within a few minutes. It is therefore recommended to additionally charge the watch for at least one day's worth of charging by exposing to light or by swinging (2002-second interval 300 times) to ensure continuous operation. movement 15 14 <Time Setting Warning Feature> After the watch has been recharged after having stopped due to being undercharged, although the watch hands will begin to move, the time will not be correct. The second hand will begin irregular 2-second interval movement (moving irregularly once every 2 seconds) at this time indicating that the time is incorrect. Reset the time after sufficiently charging the watch by referring to Section 6 entitled, "Charging Procedure". When the time has been reset, the second hand will no longer move irregularly in two second intervals, and return to either 1-second or 2-second interval movement. In the case of 2-second interval movement, the watch must be additionally charged. 8. Using the Chronograph This chronograph is able to measure and display time in 0. 2 second (1/5 second) units up to a maximum of 59 minutes and 59 seconds. After completing measuring time for 60 minutes, it returns to the reset display and stops. [Chronograph Reset Display] Chronograph minutes Chronograph seconds 50 40 60 10 20 30 45 60 50 40 30 10 20 30 Irregular 2-second interval movement * If the chronograph second hand does not return to the zero second position when the chronograph has been reset, correct the second hand position by referring to Section 9 entitled, "Zeroing the Chronograph Second Hand". 16 17 <Measuring Time with the Chronograph> (1) Pressing button A starts and stops the chronograph. (2) Pressing button B when the chronograph is stopped returns the chronograph to the reset display. * If button B is pressed by mistake during chronograph measurement, the chronograph will return to the reset display. Be careful not to accidentally press button B during time measurement. A A 9. If the watch is only worn occasionally, it may stop before it is worn as a result of being undercharged. When this happens, it is necessary to recharge the watch by exposing to light or swinging and then reset the time prior to use. [. . . ] · To clean a metal, plastic, or rubber watchband, wash away dirt with mild soap and water. Use a soft brush to remove dust and dirt jammed in the gaps in the metal band. If your watch is not water-resistant, take it to your dealer. NOTE: Avoid using solvents (thinner, benzine, etc. ), as they may mar the finish. [. . . ]
