If the mode is changed again to timer mode, the time continuously counted down by the timer is displayed. However, if the timer time is up, the display retums to timer set time.

The thermometer indicates the current or last measured temperature in all modes except the chronograph mode. Temperature is measured in two ways:

1. By button operation at any time

2. Automatically measured every hour, on the hour

Temperature can be indicated either in centigrade (°C) or on Fahrenheit (°F). <Automatic temperature measurement- Temperature is automatically measured every hour, on the hour and when the mode changes from chronograph to race timer. However, if the watch is in the setting status (blinking indication) in time mode or chronograph mode at the moment of measurement, no temperature is measured. <Temperature measurement by button operation> If button ® is pressed in the normal time mode or calendar mode, temperature is repeatedly measured for 3 minutes at intervals of 2 seconds.

<Temperature measurement range and accuracy> In Centigrade (°C) On Fahrenheit scale (°F) Temperature display range -9.9°C — +59.9°C 14°F — 139°F Measurement unit 0.1°C 1°F Measurement accurac: 20°C — 30°C: #1°C 68°F — 86°F: +2°F Ÿ -5°C — 440°C: 22°C 23°F — 104°F: #4°F (Note) + Ifthe watch is wom on the wrist durning temperature measurement, the body temperature affects measurement. For accurate temperature measurement, take the watch off and leave it in the measuring environment at least for 20 to 30 minutes. The influence of body temperature depends on environmental conditions such as difference between atmospheric temperature and body temperature before taking the watch off, etc.

+ Do not use the thermometer out of the display range. Extremely hot or cold temperature may cause breakdown of the watch. Switching temperature display between centigrade and Fahrenheït> Press button ® in time or calendar mode for more than 3 seconds while pressing button @. The temperature display changes from centigrade (°C) to Fahrenheit (°F) or vice versa. If button @ is pressed before button ®, display does not change.

When the battery gets weak, the low battery indicator function appears in digital display 2 as shown below. - The second hand moves at 2-second intervals (moves by 2 increments every 2 seconds). + In time or calendar mode, the temperature display starts to blinking “ Even when the watch falls into such condition, it still displays the time but the EL light, thermometer and alarm will not function. Immediately replace the battery with new one. Blinking 2 seconds

After replacement of the battery, be sure to perform the all reset operation as shown below. Ifthe watch malfunctions or shows an abnormal display as a result of an excessive shock or static electricity (for example, the watch indicates nothing, continuously sounds alarm, etc.). Perform the all reset operation. (1) Pull the crown out. (2) Simultaneously press buttons ®, ® and (3) Release the three buttons. (a) Press the crown back. (A confirmation sound is heard.) All reset operation is complete. Before use, reset the watch for the correct time in all modes.

Some watches do not have the following bezel functions because of differences in type or design.

L. Compass function (in the northem hemisphere) Compass direction can be approximated by this function, based on the direction ofthe sun. <Finding compass direction> 12 hours Point the hour hand in the direction ofthe «LL South sun. The midpoint between the hour hand CE and the 12 hours mark is roughly equal to NES south. Point the “S” mark in the south AP direction and you can read the approximate directions of the compass. Use this indication just as a guideline because the indication changes slightiy depending on the season and latitude.

Wind <Background knowiedge= Le Windward mark In general yacht racing, such markings as KES e shown in the figure are set in the course. 2 f] Yachtsmen compete in how fast they can sail &, D É the course in the specified order. Sailing IE directions are specified by angles such as Sidemake 2|£ north =0°, east =90°, south =180°, west = EC 6||8 270°. Y & Sailing with the wind coming from the right side is called starboard, sailing with wind from the left side is called port.

Leeward mark <Using bezel-1> (1) Before setting sail, find the windward mark by the compass and set the “A” mark of the 12-hours point in the direction.

(2) The course toward the side mark from the windward mark (starboard reach) is in the direction of the green “A” mark located in the lower left side. Therefore, sail in this direction so that the yacht reaches the side mark even when the mark is hard to find because of bad weather. (3) In the same manner as (2), sail in the direction indicated by the red “A” mark in order to sail on the course from the side marking to the leeward mark (port reach). (a) For sailing from the right side marking to the left, sail the yacht in the direction of the white “A” mark. Note: The above-mentioned method is effective only when 8 is set at 45°. Ifthe 8 is 60° and the side mark projects sidewards, read the numbers above the green and red markings, otherwise the right course cannot be found. In case 8 is 30° and the side mark is inside, read the numbers under the red and green À markings.

<Using bezel-2> The yacht can sail in the windward direction Wind at an angle of 45° (high performance yacht can sail 40°). If the yacht is sailed in the windward direction before race and the obtained angle at the red or green mark (upper right or upper left) is set, the wind shift can be read during the race. Therefore, the yacht can be sailed in the most favorable direction. (Starboard tack) {Port tack)

<Using bezel-3> The bezel can be used to find the angle ofthe Direction of wind start line to the wind direction. The start line is generally set to the wind at an angle of 90°. al 2 However, it seldom is the real right angle because the wind direction changes frequentiy. Therefore, setthe white À mark in the wind direction and sail in the direction from one end to . f the other. If the sailing direction is in positive side ofthe white line of the 3-hours (or 9-hours) point, itis advantageous to set sail close to the current direction. If the current direction is in negative side of the white line, itis advantageous to take a course opposite to the mark.

  • Making full use of the three functions enables you to sail in the most favorable course.
