� The lunitidal interval is the time elapsing between the Moon�s transit over a meridian and the next high tide at that meridian. See �Lunitidal Interval� for more information. � This watch displays lunitidal intervals in terms of hours and minutes. � The �Site/Lunitidal Interval Data List� provides UTC differential and longitude information around the world. � The following is the initial factory default Home Site data (Tokyo, Japan) when you first purchase the watch and whenever you have the batteries replaced. Change these settings to match the area where you normally use the watch. UTC differential (+9.0); Longitude (East 140 degrees); Lunitidal interval (5 hours, 20 minutes)

To view the Moon data for a particular date 1. In the Tide/Moon Data Mode, press A to display the Moon Data screen. 2. Use D (+) and B (�) to display the date whose Moon Data you want to view. � You can select any date from 2000 to 2099. � You can also specify a date for tide data or Moon data. For details, see �To specify a date�. To view tide data for a particular time 1. In the Tide/Moon Data Mode, press A to display the Tide Data screen. � The initial screen shows the tide graph for 6:00 AM. 2. Use D (+) and B (�) to display the time whose Tide Data you want to view. To specify a date
1. In the Tide/Moon Data Mode, hold down A until the year setting starts to flash, which indicates the setting screen. 2. Press C to move the flashing in the sequence shown below to select the other settings.

Thermometer
This watch uses a temperature sensor to measure temperature. A reading is taken during each even-numbered minute, and the result of the last reading is displayed on the thermometer screen. The watch also takes separate readings and stores them in memory for display in the temperature tendency graph, which can be viewed in the Timekeeping Mode. Measured temperature values are stored in memory for later recall when you need them. Temperature Thermometer Screen Tendency Screen Temperature

Setting the Analog Time
Perform the procedure below when the time indicated by the analog hands does not match the time of the digital display.

Thermometer

To adjust the analog time
1. In the Timekeeping Mode, press C seven times to enter the Hand Setting Mode. 2. Hold down A until the current digital time starts to flash, which indicates the setting screen. 3. Use D to adjust the analog setting. � Press D once to advance the hands 20 seconds. � Hold down D to advance the hands at high speed. � You can select either Celsius (°C) or Fahrenheit (°F) units for the thermometer screen. See �To specify the temperature display unit� for more information. � The thermometer screen displays temperature values in 0.1°C units (or 0.2°F units). � The display range of the thermometer screen is �10.0°C to 60.0°C (or 14.0°F to 140.0°F). � You can calibrate the temperature sensor if you feel that the displayed temperature values are not correct. See �Temperature Sensor Calibration� for more information.

� To lock high speed hands movement, hold down D to start it and then press B to lock. The hands will continue to advance for one 12-hour cycle or until you press any button to stop it. It will also stop automatically after the time advances 12 hours or if an alarm (daily alarm, Hourly Time Signal, or countdown beeper) starts to sound. 4. Press A to exit the setting screen. � The minute hand will be adjusted slightly to match the seconds when you exit the setting screen. � To return to the Timekeeping Mode, press C.

Important! � Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

Temperature Tendency Graph

Tide/Moon Data
Tide graph Month � Day

Tide/Moon data lets you view the Moon age and the Moon phase for a particular date, and tidal movements for a particular date and time for your Home Site. � When you enter the Tide/Moon Data Mode, the data for 6:00 a.m. on the current date appears first. � If you suspect that the Tide/Moon data is not correct for some reason, check the Timekeeping Mode data (current time, date, and Home Site settings), and make changes as required. � See �Moon Phase Indicator� for information about the Moon phase indicator and �Tide Graph� for information about the tide graph. � All of the operations in this section are performed in the Tide/Moon Data Mode, which you enter by pressing C.

The watch also takes temperature readings at the top and the bottom of each hour and stores the results in memory for display on the temperature tendency graph. Depending on the current Timekeeping Mode time, the temperature tendency graph shows either the top of the hour measurements or the bottom of the hour measurements for the past 17 hours. From the top of each hour to the 29th minute, past top of the hour readings are shown in the graph. From the bottom of each hour to the 59th minute, past bottom of the hour readings are shown in the graph. Temperature tendency graph contents are updated every 30 minutes.

The horizontal axis of the graph represents time. The rightmost column is the newest temperature value in memory, while the leftmost column is the temperature value stored approximately 17 hours ago (1 dot = 1 hour). The vertical axis of the graph represents the relative change from one hour to the next. � When the relative change from one hour to the next exceeds +10.0ºC (+18.0ºF), the dot at the highest point for the applicable hour flashes. � When the relative change from one hour to the next exceeds �10.0ºC (�18.0ºF), there is no dot in the applicable hour's column. � If a measurement error occurs for some reason, only a single the dot in the center column will be displayed.
Temperature change greater than +10.0°C (+18.0°F) Temperature change greater than �10.0°C (�18.0°F) Error

� When you enter the Tide/Moon Data Mode, the data that appears first is the Moon data (Moon age and Moon phase indicator) for the current date as kept by the Timekeeping Mode.
