A. BEFORE USING This watch is powered not by an ordinary battery, but by converting photo energy to electrical energy. B. SETTING THE TIME AND DATE Minute hand Date Local time hours hand Before using, expose to light and make sure the watch is sufficiently charged. See "G. TIME REQUIRED FOR CHARGING" for charging time reference. Date and Hour hand correction position Crown A secondary battery is used in this watch to store electrical energy.
WSetting the Time WSetting the Date (1) Pull the crown out to the time correction position. (The second hand stops when the crown is pulled out.) (2) Turn the crown to set the 24 hour hand and minute hand to the current time. At this time, the movement of the hour hand is linked with the movement of the 24 hour hand. (3) Push the crown back in to the normal position. (The second hand begins to move when the crown is pushed in.) (4) Pull the crown out to the date correction position.
C. USING AS A DUAL TIME WATCH This watch allows the hour hand only to be corrected independently without stopping the watch. It can be used as a dual time watch by setting the 24 hour hand and hour hand to different times. After correcting the time, the hour hand is used to indicate the "local time hours". Hour (local time hour) hand Minute hand Local time correction position WCorrecting the Local Time Hours (1) Pull the crown out to the local time correction position.
D. FUNCTIONS OF SOLAR POWERED WATCH If the charge becomes insufficient, a warning function will operate and the display changes, as below.
WInsufficient Charge Warning Function 2sec. 2 s ec. The second hand changes to a two second interval movement to indicate insufficient recharging. Even in such a case, the watch keeps correct time, but about 3 days after the two second interval movement begins, the watch will stop. After exposing the watch to light, recharging takes place and the watch returns to one second interval movement. WQuick Start Function 2sec. 2 s ec.
E. CARE AND HANDLING DURING CHARGING F. REPLACING THE SECONDARY BATTERY WNotes on use Unlike ordinary batteries, the secondary battery used in this watch doesn't have to be periodically replaced due to repeated charging and discharging. Take care to charge your watch during use. Please note that if you wear long sleeves, the watch can easily become insufficiently charged because it is hidden and not exposed to light.
G. TIME REQUIRED FOR CHARGING * The recharging time is the time when the watch is continuously exposed to radiation. Time required for recharging may vary according to the design (color of the dial, etc.) and operating environment. The following table will serve you as rough reference. Time required Illuminance (lux) Environment 500 inside an ordinary office 22 hours 1000 60-70cm (24-28in.) under a fluorescent light (30W) 11 hours 45 minutes 158 hours 3000 20cm (8in.
H. USING THE SLIDE RULE Flying distance and other navigation calculations as well as general calculations can be performed using the slide rule located around the outside of the dial. This slide rule is not able to display decimal places for calculation results, and should only be used as a general reference as an alternative to more accurate calculations. Turning the crown at the 8:00 position allows the slide rule around the dial (Outside Scale) to be rotated. A. Navigation Calculator 1.
2. Speed (Ground Speed) Calculation Question: What is the speed (ground speed) of an airplane when it takes 1 hour and 20 minutes to fly a distance of 240 nautical miles? Solution: Align the 24 on the outside scale with 1:20 (80) on the inside scale. At this time, 18 is aligned with the SPEED INDEX (Y) on the inside scale, and the answer is 180 Kt. 18 3.
4. Fuel consumption rate calculation Question: If 120 gallons of fuel are consumed in 30 minutes’ flying time, what is the fuel consumption rate? Solution: Align the 12 of the outside scale with 30 of the inside scale. The SPEED INDEX (Y) now points to 24, and the answer is 240 gallons per hour. 20 5.
6. Maximum flying hours Question: With a fuel consumption rate of 220 gallons per hour and a fuel supply of 550 gallons, what is the maximum number of flying hours? Solution: Align the 22 of the outside scale with the inside scale’s SPEED INDEX (Y) of the inside scale. The 55 of the outside scale is now aligned with 2:30, and the answer is 2 hours and 30 minutes. 22 7.
B. General calculation functions 1. Multiplication Question: 20 M 15 10 on the inside scale, and read Solution: Align 20 on the outside scale with X the outside scale at the 30 mark which is aligned with 15 of the inside scale. Figure the number of decimal places, and the answer is 300. Remember: decimal places cannot be read on this scale. 24 2. Division Question: 250/20 Solution: Align 25 on the outside scale with 20 on the inside scale. On the 10 on the outside scale read the 12.
3. Reading Ratios Question: 30/20 = 60/x Solution: Align 30 on the outside scale with 20 on the inside scale. At this time, the answer of 40 can be read from the inside scale corresponding to 60 on the outside scale. In addition, the ratio of the value on the outside scale to the value on the inside scale is 30:20 at all positions on the scales. 26 4. Determining Square Root Question: What is the square root of 225? Solution: Rotate the scales so that the value on the inside scale corresponding to 22.
I. PRECAUTIONS 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. CAUTION: Water-resistance performance There are several types of water-resistant watches, as shown in the following table.
• 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.
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 deterioration of functions 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.
