[Procedure for Setting the Time] 1. Pull the crown out to the time correction position (second click) when the second hand has reached the zero seconds position. 2. Set the time by turning the crown. Hour hand Minute hand • The date changes at 12:00 AM. Pay attention to AM Normal and PM when setting the position (0) time. 3. Return the crown to the normal position (0 position) 7 in synchronization with a telephone time signal or Time correction other time service.
PAGE 5
Helpful Hint for Accurately Setting the Time: After stopping the second hand at the 0 seconds position, advance the minute and hour hands 4-5 minutes past the correct time and then move them back to the correct time. Setting the time in this manner eliminates any play in the gears of the watch movement. The hands of the watch can be made to advance at the correct time by pushing in the crown in synchronization with a telephone time signal or other time signal.

Press button (A) when the watch is in the chronograph reset state to start timing. Press button (A) again to stop timing.

2.Press button (B) to reset the chronograph to 0 seconds after it has been stopped. • The chronograph is not reset if button (B) is pressed while timing is in progress. To reset the time, press button (B) after first interrupting timing by pressing button (A). * If the chronograph is repeatedly started and stopped without resetting, the chronograph hands may rarely shift from the 12:00 position after 12 hours have elapsed.
PAGE 8
7. Using the Alarm • The alarm function uses a 12 hour indicator hand. • When the alarm hand has been set to ON, the alarm sounds for 20 seconds when the set time is reached. Furthermore, the alarm will only sound once. Since the alarm is based on 12 hour clock, the alarm sounds twice in the AM and PM when it has been set. • Since an indicator hand is used to set the alarm time, there is a certain degree of error in the set alarm time.
PAGE 9
8. Viewing the Charge Indicator • This charge indicator provides a general indication of the current level at which the secondary battery is charged to one of four levels. • The charge indicator hand points to the center of each level. • The charge indicator only provides a rough estimate of the level at which the secondary battery is charged. You can refer to this level when using your watch. It is recommended that the watch normally be charged to at least level 2.
PAGE 10
9. General Reference for Charging Times The time required for charging varies according to the model of the watch (color of the dial, etc.). The following times are shown below to serve only as a reference. * Charging time refers to the amount of time the watch is continuously exposed to light. Charging time Illuminance (lux) 500 Charging time required for 1 day of operation Charging time to level 1 (1second interval movement) from stopped state Inside an ordinary office 3.
PAGE 11
10. Functions Unique to Solar-Powered Watches If the watch has changed from the normal time display to the insufficient charge warning display, charge the watch by allowing light to shine on it while referring to section 9 entitled “General Reference for Charging Times” until the charge level indicator hand points to “Level 3”.
PAGE 12
[Insufficient Charge Warning Feature] This feature indicates that the watch has become insufficiently charged when the second hand changes from 1-second interval movement to 2-second interval movement. When this occurs, promptly charge your watch. Furthermore, the chronograph and alarm functions will not operate in this state.
PAGE 13
WARNING: Handling of Secondary Battery • Never attempt to remove the secondary battery from the watch. • If the secondary battery must unavoidably be removed, store it out of the reach of small children to prevent accidental swallowing. • If the secondary battery should happen to be swallowed, consult a physician immediately and seek medical attention. • Send in your watch for repairs when it is necessary to replace the secondary battery. 26 12.

13. 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.

15. Precautions WARNING: Water-resistance performance For correct use within the design limits of the watch, confirm the level of waterresistance of your watch, as indicated on the dial and case, and consult the table. Examples of use There are several types of water-resistant watches, as shown in the following table. The unit "bar" is roughly equal to 1 atmosphere. * WATER RESIST(ANT) xx bar may also be indicated as W.R. xx bar.
PAGE 17
WARNING: Water-resistance performance • Water-resistance for daily use (to 3 atmospheres): This type of watch is water-resistant to minor exposure to water. For example, you may wear the watch while washing your face; however, it is not designed for use underwater. • Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is water-resistant to moderate exposure to water. You may wear the watch while swimming; however, it is not designed for use while skin diving.
PAGE 18
CAUTION: Operating environment • Use the watch within the operating-temperature range specified in the instruction manual. Using the watch where temperatures are outside the specified range, may result in deteri ctions or even stoppage of the watch. • Do NOT use the watch in places where it is exposed to high temperature, such as in a sauna. Doing so may result in a skin burn. • Do NOT leave the watch in a place where it is exposed to high temperature, such as the glove compartment or dash-board of a car.
