W W 1. Y our W atch World Time Eco-Drive Radio Controlled Watch <Radio Signal Reception Function> This watch is a radio controlled watch, which receives the standard time radio waves that are br.
10 11 Important Points Regarding Radio Wave Reception There are two methods to receive radio signals during normal operation, Automatic and On Demand. The internal unidirectional antenna may be weakened by geography or building structures, which may require the user to place the watch near a window.
12 13 Check the reception status. • Pull out the crown to position 1. • Turn the crown to align the mode hand with TME. • Return the crown to the normal position.
14 15 1. Pull the crown out to position 1 and turn to align the mode hand with CHR (chronograph mode). 2. Pull out the crown to position 2. • The hands will move rapidly, stopping at the reference position recorded in the watch memory.
16 17 3. Set the home time. If the home time is correct, (1) Set the time manually (p. 48) (2) Set the time by receiving the radio wave (p. 20) Caution: If the home city is set to a city that is outside the reception area, the radio wave cannot be received.
18 19 Automatic reception • It is not necessary to operate buttons during automatic reception. • The watch will automatically receive the radio wave every day at 2 a.m., 3 a.m. and 4 a.m. • The 4 a.m. reception can be changed to any time of the day.
20 21 Recovery Automatic Reception (Automatic Reception) • If the watch stops due to insufficient charging, expose the watch to sunlight to recharge it. When the watch is recharged sufficiently, it will automatically receive the radio wave once. * Regularly charge your radio controlled watch so it does not become insufficiently charged.
22 23 W W 5. Poor Reception Areas It may not be possible to receive radio waves under environmental conditions where reception is difficult or in areas susceptible to radio noise, such as those shown in the illustrations below. While referring to the reception level display, try to find a location with better reception.
24 25 <Time required for reception> Reception can take from about 2 minutes to a maximum of 15 minutes, depending on factors such as the weather or noise. If the radio wave reception fails, the watch may return immediately to the normal display.

81 80 Model 2 A. Navigation Calculator 1. Calculation of time required Problem: How long does it take an airplane flying at 180 knots to fly a distance of 450 nautical miles? Solution: Set the 18 mark on the outside scale to the SPEED INDEX ( Y ).
83 82 3. Flying distance calculation Problem: What is the flying distance traveled in 40 minutes at a speed of 210 knots? Solution: Align the 21 on the outside scale with the SPEED INDEX ( Y ) of the inside scale. The 40 of the inside scale is now pointing to 14, and the answer is 140 nautical miles.
85 84 5. Fuel consumption calculation Problem: How much fuel is consumedin 6 hours at a fuel consumption rate of 250 gallons per hour? Solution: Align the 25 of the outside scale with the inside scale’s SPEED INDEX ( Y ) of the inside scale. The 6:00 is aligned with 15, and the answer is 1500 gallons.
87 86 7. Conversion Problem: How do you convert 30 miles into nautical miles and kilometers? Answer: Align the 30 on the outside scale with the STAT ( Y ) mark on the inside scale. At this time, 26 nautical miles is aligned at the NAUT ( Y ) mark on the inside scale, while the answer of 48.
89 88 2. Division Problem: 250/20 Solution: Align 25 on the outside scale with 20 on the inside scale. On the outside scale read the 12.5 mark that is aligned with 10 on the inside scale. figure the number of decimal places, and the answer is 12.5. B.
91 90 4. Determining Square Root Problem: What is the square root of 225? Solution: Rotate the scales so that the value on the inside scale corresponding to 22.5 on the outside scale is equal to the value on the outside scale corresponding to 10 on the inside scale, and read off the answer of 15 at that location.
93 92 j Wearing clothes with long sleeves makes it difficult for the watch to get the necessary light, resulting in insufficient charging. We recommended that you charge the watch for a long time in direct sunlight once a month. [Caution] Do not charge on surfaces that can easily become hot, such as a car dashboard.
95 94 * 1. When the watch stopped due to insufficient charging • It takes at least 30 minutes to recharge sufficiently to perform recovery automatic reception, even if the watch is being exposed to light. After recovery, refer to “Guide to Charging Time” (p.
97 96 <Canceling the power saving function> The power saving function will be automatically canceled when the watch face is exposed to light. • When power saving 1 is canceled, the digital display is restored.
99 98 j If the charging insufficiency occurs during radio signal reception, the operation will stop automatically, the watch will return to the time before the operation, and 2- second interval movement will begin. Regularly charge your radio controlled watch so it does not become insufficiently charged.
101 100 For a 1-day movement charging time ... The charging time to run the watch for one day with normal movement. Time for full charging ... The time for full charging after the watch has stopped due to an insufficient charging. [Caution] A fully charged battery will run the watch for about 6 months without further charging.
103 102 CAUTION Charging precautions j Do not charge the watch in a high-temperature environment (about 60°C / 140°F or more). Overheating while charging can cause the watch exterior to become discolored, the watch to deform or the movement to be damaged.
105 104 Problem Radio signals cannot be received. Check • Are there objects nearby that could block radio signals or generate noise? • Avoid objects that block radio signals or generate noise. Try to receive radio signals by pointing the 9:00 position of the watch in the direction of the radio signal transmitter.
107 106 Problem The time is not correct. The watch successfully received the radio wave, but it deviates slightly from the correct time. The second hand moved suddenly to the reception standby (RX) position. Check • Check the reception status. • Check whether the daylight saving time is ON or OF (off).
109 108 Problem The second hand is moving in 2- second intervals. The hands moved forward quickly at the moment that the watch was removed from a desk or drawer.
111 110 NO NO NO NO OK NO NO NO OK OK NO NO Moderate exposure to water (washing, kitchen work, swimming, etc.) Marine sports (skin diving) Scuba diving (with air tank) Examples of use 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.
113 112 • If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, buttons, etc.) may come off. CAUTION: Keep your watch clean.
115 114 • Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases. If solvents, such as thinner and benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc.
117 116 • Daylight saving time on/off • Calendar: Month, date, day of week (perpetual calendar until December 31, 2099) 6. Additional functions • Radio signal reception function (automatic recep.
119 118 7. Operation time: • Time from a full charge until the watch stops without charging : About 3.5 years (when in the power saving mode) : About 6 months (when not in the power saving mode) (The operation time may vary depending on the conditions of use, such as how many times the radio wave is received.
