FUNCTIONS OF SOLAR POWERED WATCH.8 Insufficient Charge Warning Function.10 Quick Start Function.10 Time Setting Warning Function.11 Overcharge Prevention Function.11. BEFORE USING This watch is powered not by an ordinary battery, but by converting photo energy to electrical energy.

Before using, expose to light and make sure the watch is sufficiently charged. TIME REQUIRED FOR CHARGING' for charging time reference.

• * Since the date is linked to movement of the hour hand, the date changes when the hour hand approaches 12:00 midnight. Please note this operation when using as a dual time watch. * Do not attempt to correct the calendar when the hour hand is between the hours of 9:00 PM and 1:00 AM.

• 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'. FUNCTIONS OF SOLAR POWERED WATCH If the charge becomes insufficient, a warning function will operate and the display changes, as below. Normal time display If insufficiently charged If sufficiently charged One second interval movement Insufficient charge warning display If insufficiently. • 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. • Please note that if you wear long sleeves, the watch can easily become insufficiently charged because it is hidden and not exposed to light. • When you take the watch off, place it in as bright a place as possible, and it will always continue to run properly.

• * The recharging time is the time when the watch is continuously exposed to radiation. Full recharging time. The time for fully recharge from stopped. Embird 2010 Build 8.8 D Crack.

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. 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. 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. 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. General calculation functions 1. Multiplication Question: 20 M 15 Solution: Align 20 on the outside scale with 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.

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. • WATER RESIST(ANT) The unit 'bar' is roughly equal to 1 atmosphere. For correct use within the design limits of the watch, confirm the level of water- resistance of your watch, as indicated on the dial and case, and consult the table.
