• Normally, your watch should show the correct time as soon as you select your Home City code. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You also can perform manual receive or you can set the time manually.

• The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between city codes and transmitters, see “Important!” under “Time Calibration Signal Reception” and “Transmitters”.

• See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.

• You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.

• Auto Receive

With auto receive, the watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. For more information, see “About Auto Receive”.

• Manual Receive

Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.

Important!

• When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side facing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.

12 o’clock

• Make sure the watch is facing the right way.

• Proper signal reception can be difficult or even impossible under the

conditions listed below.

Inside or among buildings

• Signal reception normally is better at night than during the day.

• Time calibration signal reception takes from two to seven minutes, but in

some cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.

• The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below.

* The areas covered by the HNL, and ANC city codes are quite far from

the time calibration signal transmitters, and so certain conditions may cause problems with signal reception.

Operation Guide 3147

Note

• When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.

• Auto receive of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.

• The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches a calibration time. Do not perform any button operation within seven minutes before or after 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 Signal Strength Indicator

The signal strength 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 signal strength indicator is displayed while an auto or manual receive operation is in progress.

Signal strength indicator

Weak

• Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the signal strength indicator to indicate signal strength.

• Use the signal strength 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 watch’s time setting, the Level 3 signal strength indicator will remain on the display in all modes. The Level 3 signal strength indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

• The Level 3 signal strength 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 3 signal strength indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 3 signal strength indicator disappears from the display each day when the first auto receive operation of the day is performed.

•

Change the DST setting to Auto DST.

• Select the correct Home City code.

Altimeter

The watch’s 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 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 readings in memory.

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 readings is also affected by temperature. When taking altitude readings, make sure the watch is not subjected to temperature changes.

• To avoid the effect of sudden temperature changes during readings, keep the watch on your wrist in direct contact with your skin.

• Do not rely upon this watch for altitude readings 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 taking altitude readings 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.

Operation Guide 3147

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 watch’s barometric pressure sensor is converted 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 will use that value to convert the current barometric pressure reading to altitude.

• When mountain climbing, you can specify a reference value in accordance with a marker along the way or altitude information from a map. After that, 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 a window in the upper left of the display. You can select either of the following two altitude measurement intervals.

0'05": Readings at five-second intervals for one hour 2'00": Readings at five-second intervals for the first three minutes followed

by two-minute intervals for 10 hours

• For information about configuring settings for the altitude reading interval and duration, see “To specify the altitude reading interval”.

Important!

• The procedure below simply displays a value indicating your current altitude, without recording it in watch memory. For information about recording altitude readings in watch memory, see “Saving Altitude Readings in Memory”.

Notes

• Normally, displayed altitude values are based on the watch’s preset conversion values. You also can 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).

• An altitude reading may be displayed be a negative value in cases where there is a reference altitude value specified or because of certain atmospheric conditions.

• The displayed altitude value changes to altitude reading falls outside the measurement range. The altitude value will be displayed again as soon as the altitude reading is within the allowable range.

• You can select either meters (m) or feet (ft) as the measurement unit for displayed altitude value.

• During altitude measurements, the watch may not be able to update its timekeeping display contents normally. Correct timekeeping is maintained internally, however.

Saving Altitude Readings in Memory

The following describes the different types of records the watch creates for altitude readings.

• You can take manual altitude readings, which are stored in memory along with the date (year, month, day) of the reading. There is enough memory to hold up to 20 altitude records (readings).

• The Altimeter Mode has a stopwatch (which is independent of the watch’s Stopwatch Mode) that you can use to time your climbs. While the Altimeter Mode stopwatch is running, the watch takes altitude readings automatically (without storing them in memory). Each time you reset the Altimeter Mode stopwatch to all zeros, the highest altitude, lowest altitude, cumulative ascent, and cumulative descent achieved during the last Altimeter Mode stopwatch session are stored in a “current stopwatch session record”.

• A separate “historical record” keeps track of the highest altitude, lowest altitude, cumulative ascent, and cumulative descend of all past Altimeter Mode stopwatch sessions.

• At this time the watch will beep and the current altitude reading will be saved along with the current date (year, month, day) and time.

3. REC will stop flashing and the watch will return to the Altimeter Mode automatically after data save is complete.

• Memory can hold up to 20 altitude records. Storing a new reading while

there already are 20 in memory will delete the oldest record to make room for the new reading.

To take altitude readings using the Altimeter Mode stopwatch

1. In the Timekeeping Mode, use the C button to enter the Altimeter Mode.

• The watch will start altitude measurement automatically. Note that

readings are not saved as altitude records.

2. Press the E button to start and stop the Altimeter Mode stopwatch.

• While an Altimeter Mode stopwatch operation is in progress, the display

shows the elapsed time, current altitude, and the change in altitude since the start of the stopwatch operation.

3. After you are finished using the Altimeter Mode stopwatch, press the B button to reset it to all zeros.

• While an Altimeter Mode stopwatch operation is in progress, you can toggle

between the altitude graph and the altitude change indicator by pressing the A button. The altitude change indicator graphically shows how the current altitude reading differs from the previous reading. The type of indicator that appears depends on the relative size of the altitude change.
