Radio-controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.
This watch is designed to pick up the time calibration signal transmitted in Germany (Mainflingen), England (Rugby), and the United States (Fort Collins) and the time calibration signals transmitted in Japan.
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration signal. You can also perform a manual procedure to set the time and date, when necessary.
The first thing you should do after purchasing this watch is to specify your Home City (the city where you normally will use the watch). For more information, see To specify your Home City” below.
When using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.
The U.S. time calibration signal can be picked up by the watch while in North America.
* The term North America in this manual refers to the area that consists of
Canada, the continental United States, and Mexico.

The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.
Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.
About the Receiving Indicator
The receiving indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest. The receiving indicator is displayed while an auto or manual receive operation is in progress.

Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.
Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.
Following reception of the time calibration signal and calibration of the watchs time setting, the Level 5 receiving indicator will remain on the display in all modes. The Level 5 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.
The Level 5 receiving indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.
The Level 5 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 5 receiving indicator disappears from the display each day when the first auto receive operation of the day is perfor med.

Angle value (in degrees)
During measurement, the watch displays an angle value, a direction indicator, and four direction pointers, which change dynamically when the watch is moved. After measurement is complete, the angle value, direction indicator, and four direction pointers are frozen in accordance with the last measurement.
The ACT indicator flashes on the display while a measurement is in progress.
Note
Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in large measurement error.
The margin of error for the angle value is ±11 degrees. If the indicated direction is northwest (NW) and 315 degrees, for example, the actual direction can be anywhere from 304 to 326 degrees.
Any ongoing direction measurement operation is paused temporarily while the watch is performing an alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by pressing L). The measurement operation resumes for its remaining duration after the operation that caused it to pause is finished.

In some areas, barometric pressure is expressed in millibars (mb) instead of hectopascals (hPa). It really makes no difference, because 1hPa = 1mb.
You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured barometric pressure, and Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See To select the temperature, barometric pressure, and altitude units”.
See “Barometer and Thermometer Precautions for important precautions.
Barometric Pressure Graph
Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. This watch takes barometric pressure measurements automatically every two hours (at the top of each even-numbered hour), regardless of its current mode. Measurement results are used to produce barometric pressure graph and barometric pressure differential pointer readings. The barometric pressure graph shows readings of previous measurements for up to 30 hours. The horizontal axis of the graph represents time, with each dot standing for two hours. The rightmost dot represents the most recent reading. The vertical axis of the graph represents barometric pressure, with each dot standing for the relative difference between its reading and that of the dots next to it. Each dot represents 1hPa. The following shows how to interpret the data that appears on the barometric pressure graph.

This pointer indicates the relative difference between the most recent barometric pressure reading indicated on the barometric pressure graph, and the current barometric pressure value displayed in the Barometer/ Thermometer Mode.
Pressure differential is indicated in the range of ±15 hPa, in 1-hPa units.
The barometric pressure differential pointer is not displayed when the
displayed current barometric value is outside of the allowable measurement range (260 to 1,100 hPa).
Barometric pressure is calculated and displayed using hPa as the standard. The barometric pressure differential can also be read in inHg units as shown in the illustration.

About Barometric and Temperature Measurements
Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer/Thermometer Mode. After that, barometric pressure and temperature measurements are taken every five seconds.
The ACT indicator flashes on the display while a measurement is in progress.
You can also perform a barometric pressure and temperature measurement at any time by pressing B in the Barometer/Thermometer Mode.

Altimeter

The watchs altimeter uses a pressure sensor to detect current air pressure, which is then used to estimate the current altitude based on ISA (International Standard Atmosphere) preset values. You can also specify a reference altitude, which the watch will use to calculate your current altitude based on the value you specify. Altimeter functions also include storage of measurement data in memory and an altitude alarm.
Important!
This watch estimates altitude based on air pressure. This means that altitude readings for the same location may vary if air pressure changes.
The semiconductor pressure sensor used by the watch for altitude measurements is also affected by temperature. When taking altitude measurements, make sure the watch is not subjected to temperature changes.
To avoid the effect of sudden temperature changes during measurement, keep the watch on your wrist in direct contact with your skin.
Do not rely upon this watch for altitude measurements or perform button operations while sky diving, hang gliding, or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in any other activity where there is the chance of sudden altitude changes.
Do not use this watch for measuring altitude in applications that demand professional or industrial level precision.
Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings produced by this watch will not match the altitude readings announced or indicated the flight crew.
How the Altimeter Measures Altitude
The altimeter can measure altitude based on its own preset values, or a reference altitude specified by you.
When you measure altitude based on preset values
Data produced by the watchs barometric pressure sensor is conver ted to approximate altitude based on ISA (International Standard Atmosphere) conversion values stored in watch memory.
When you measure altitude using a reference altitude specified by you
After you specify a reference altitude, the watch uses that value to convert the current measured barometric pressure value to altitude.
To determine the height of a tall building, for example, specify zero for the reference altitude value while you are on the ground floor. Then when you go to a higher floor, the altitude displayed by the watch will indicate the height from the ground floor. Note that you may not be able to get a good reading if the building is pressurized or air-conditioned.
When mountain climbing, you can set the reference value in accordance with a marker along the way or altitude information from a map. After that, the altitude readings produced by the watch will be more accurate than they would without a reference altitude.

Displaying Your Current Altitude
You can use the procedure described in this section to display your current altitude. If you leave the watch in the Altimeter Mode, it will update the displayed altitude value regularly, and indicate reading-to-reading changes in the altitude graph at the top of the display.
Important!
The procedure in this section simply displays values indicating your current altitude, without storing them in watch memory. For information about recording altitude readings in watch memory, see “Saving Altitude Data”.

Notes
Normally, displayed altitude values are based on the watchs preset conversion values. You can also specify a reference altitude, if you want. See Specifying a Reference Altitude”.
Altitude is displayed in units of 5 meters (20 feet).
The measurement range for altitude is 700 to 10,000 meters (2,300 to
32,800 feet).
The measured altitude may be a negative value in cases where there is a reference altitude value set or because of certain atmospheric conditions.
The displayed altitude value changes to measured altitude falls outside the measurement range. The altitude value will be displayed again as soon as the measured altitude is within the allowable range.
You can change the measurement unit for displayed altitude values to either meters (m) or feet (ft). See “To select the temperature, barometric pressure, and altitude units”.
Saving Altitude Data
The save operation described in this section creates records of altitude measurement data in watch memory. When you start a save session, measurement continues to be performed (indicated by the REC indicator flashing on the display) even if you change to another mode.
Types of Altitude Data Records
A save session stores three types of altitude records in memory: periodic records (up to 40), a current session record, and a historical record.
Periodic Records
A save session creates up to 40 altitude records at fixed intervals and stores them in memory. You can use the Data Recall Mode to view these records.
How periodic records are created and saved Note
The following operation is performed simultaneously with the operation described under How current session record data is updated”.
1. When you hold down C to start a save session, the watch creates
Periodic Record 1, which contains the current date (month and day), time, and altitude.
Starting a new save session clears any periodic records currently in
2. Next, the watch takes readings for Periodic Record 2 up to Periodic Record
40 at minute 00, 15, 30, and 45 of each hour.
