• The measurement functions built into this watch are not intended for use in taking measurements that require professional or industrial precision. Values produced by this watch should be considered as reasonably accurate representations only.

• Though a useful navigational tool, a GPS receiver should never be used as a replacement for conventional map and compass techniques. Remember that magnetic compasses can work at temperatures well below zero, have no batteries, and are mechanically simple. They are easy to operate and understand, and will operate almost anywhere. For these reasons, the magnetic compass should still be your main navigation tool.

Setting Up the GPS Mode

The following are settings you need to make before actually taking any measurements with the GPS Mode. Most of these need to be made only the first time you use the watch. See the referenced pages for full information about each setting.

• Area setting (See “Setting Your Area”)

• Datum setting (See “Setting a Datum”)

• Distance unit setting (See “Setting the Distance Unit”)

• Speed unit setting (See “Setting the Speed Unit”)

Important!

• The Timekeeping Mode time and date settings are also used to determine the current positions of satellites. Make sure that your time and date setting are always accurate.

Taking a GPS Measurement

The following are the basic steps for taking a position measurement in the GPS Mode. See the referenced pages in this manual for further details. The following procedure uses the One-Shot Mode as an example. See “GPS Measurement Modes” for information about other measurements.

Important!

• GPS measurements may take a long time to complete or may even be impossible due to satellite and other conditions.

To take a GPS measurement

1. While a GPS Data Screen is on the display, press ●.

• This example procedure starts from the

Position Screen.

• This changes to the Satellite Search

Screen.

• The indicator flashes above GPS at the

Antenna

2. When the measurement is successful, the watch beeps a number of times and returns to the GPS Data Screen you started from in step 1.

• See “To add a landmark by registering your current location” for information

about storing GPS measurement data in Landmark Memory.

• See “GPS Measurement Modes” for more information about indicators and

how the watch updates measurement data.

• If the watch is unable to successfully complete the measurement within

about two minutes, it plays a short tune and displays SATELLITE at the top of the display to let you know. If this happens, press ● twice to return to the GPS Data Screen, move to a more open area, and try again.

• If you perform the above GPS measurement operation within the area

bottom of the screen to indicate that the watch is searching for overhead satellites.

• To interrupt an ongoing GPS measurement, press ● again.

• Make sure the antenna is pointing up at the sky while a measurement is taking place.

GPS Measurement Modes

You can select from among four different GPS measurement modes. The mode you should select depends on how quickly you want your position data updated balanced against how important it is for you to conserve remaining battery power. Remember, however, that no matter which GPS measurement mode you use, it can take a considerable amount of time to achieve the first measurement.

One-shot measurement with standby for subsequent measurements

One-shot measurement with no standby (power save)

Continuous measurement with standby for subsequent measurements

Continuous measurement with semi-standby (power save)

• The standby modes provide faster updating of measurement data following the first measurement, but they consume more battery power because the watch’s GPS circuit remains in standby (half power). The indicator flashing above GPS at the bottom of a GPS Data Screen indicates that GPS measurement is in standby.

To perform:

Use:

Quick Mode

One-Shot Mode

Continuous Mode

Auto Mode

Page 4

1840-4

• The non-standby modes take longer to produce subsequent measurements, but shutdown of the watch’s GPS circuit between measurements conserves battery power. In these modes, the indicator above GPS at the bottom of a GPS Data Screen does not flash and an indicator appears above SAVE to indicate power save is enabled.

Quick Mode

The Quick Mode performs a GPS measurement when you press ● and updates the GPS Data Screen. After the first measurement, the watch’s GPS circuit remains in standby, which is indicated by the flashing indicator above GPS at the bottom of the GPS Data Screen. Because of this, subsequent measurements are produced more quickly. Continuous Quick Mode standby uses battery power. To exit standby, press J while the Position Screen is on the display to change to another measurement.

One-Shot Mode

The One-Shot Mode also performs GPS measurement when you press ● and updates the GPS Data Screen. In this mode, however, the watch’s GPS circuit is shut down between measurements. Because of this, it takes more time to perform each measurement.

Continuous Mode

The Continuous Mode performs a GPS measurement every second starting when you press ● and ending when you press ● again. The GPS Data Screen is updated with each measurement. In the Continuous Mode, the watch’s GPS circuit remains in standby, which is indicated by the flashing indicator above GPS at the bottom of the GPS Data Screen.

Auto Mode

The Auto Mode also performs a GPS measurement every minute starting from when you press ● and ending when you press ● again. The GPS Data Screen is updated with each measurement. Though the GPS circuit shuts down between measurements in this mode, the indicator above GPS continues to flash until you press ● to stop measurement.

Important!

• The indicator flashing above GPS at the bottom of a GPS Data Screen indicates that the GPS circuit is activated, which consumes valuable battery power. To prolong battery life, be sure to use the following operations to turn off the GPS circuit when you are not using it.

• Press ● to stop position measurement and turn off the GPS circuit. The indicator above GPS stops flashing at this time.

Track Memory

Track point data is automatically stored into track memory when you perform a GPS position measurement. Track memory can hold up to 100 track point data records, each of which contains a record number, track position (latitude and longitude), measurement date, and measurement time. Track point data is used as the basis for the tracks that are plotted on the GPS Mode Plot Screens. You can also recall track memory records and view the data contained in each.

• After the track memory becomes full with 100 track point data records, each

new measurement causes the oldest record in memory to be deleted to make room for the new data.

When track point data is stored

The following describes the timing when track point data is stored into track memory.

• Quick Mode/One-Shot Mode

Track point data is stored each time a GPS measurement is successful.

• Auto Mode/Continuous Mode

Track point data is stored every 10 minutes.

• In the case of a GPS Continuous Mode measurement operation, the screen data is refreshed every second. To refresh the display in other GPS measurement modes, press MENU to return to the Menu Screen and then press ● again.

Satellite Marks

Searching This mark indicates a satellite from which the watch is standing by to receive a signal. The positions of these satellites are determined using almanac data for the current latitude, longitude, and time.

Tracking This mark indicates a satellite that is currently being tracked by the watch. Signal receipt for these satellites is enabled.

1. In any mode, press the MENU button to display the Menu Screen.

2. Use L and K to highlight SATELLITE, and then press ●.

• Satellite information appears immediately

if a GPS measurement operation is already in progress.

• If a GPS measurement operation is not in

progress, the message WAIT remains on the display as data is being collected.

Datums

Since the Earth is neither flat nor a perfect sphere or even an ellipsoid, a wide variety of spheroid models (mostly ellipses) were developed with different major and minor axes. An ellipsoid, in addition to the various control points required to relate how the ellipsoid lies in relation to the Earth constitutes a map datum. When various countries mapped their areas, each usually used its own datum to provide accuracy in a specific area. Though some datums share the same ellipsoid, they use different control points, which results in differing datums. The development of air travel between countries created the need for a single global datum, which is identified according to their World Geodetic System (WGS) names. The constellation of GPS satellites uses WGS 84 to describe coordinates. It should be noted that errors of several hundred meters can occur if coordinates of one datum are referred to in another datum without converting them first.

Maps and Gridlines

Most maps are marked with horizontal and vertical lines that form a squares of a map’s grid are called The gridlines of some maps are spaced a number of inches or millimeters apart, while others have gridlines spaced a number of minutes of latitude and longitude. It is this latter type of map with

What is GPS?

The Global Positioning System (GPS) was originally developed and is currently operated by the United States Department of Defense. The space segment of the GPS consists of the NAVSTAR satellites that are orbiting 21,000 kilometers above the Earth over six equally spaced orbital planes. When signals are received from a minimum of three satellites, the principal of triangulation is used to determine the current location of the GPS Watch based on the distance between each satellite and the watch, and the orbital path of each satellite.

Important!

• The signals produced by GPS satellites are controlled by the GPS Master Control Station at Colorado Springs, Colorado. Signals may be subject to reduced precision and even interruption without notice.

Almanac and Ephemeris Data

The data message sent from a GPS satellite consists of an gives the approximate positions of all the other satellites in the system, and the satellite the host satellite. How quickly the watch is able to acquire the data it needs to determine your position depends on a number of factors. One of the most important factors is the status of almanac and ephemeris data in watch memory. There are two possible data conditions from which you can start when performing a GPS measurement:

Important!

• The above terms and their definitions are based on current standard

Whenever the watch determines that the almanac data it currently has in memory is no longer valid, it receives new almanac data from one of the satellites overhead. The message RECEIVING SATELLITE DATA appears on the display of the watch to indicate when almanac data is being received. Be sure to leave the watch with its antenna facing the sky whenever this message is on the display.

GPS Measurement Tips

Check the following points whenever GPS measurements seem to take too long or when you are unable to achieve successful measurements.

❑ Are the watch’s AREA, DATUM, and TIME settings correct? ❑ Are you in a building with a roof, heavily wooded area, or any other

area where you cannot directly see the sky?

❑ Are you using an old battery? ❑ Is the low battery power message on the display of the watch? ❑ Are you near high-voltage lines, near a person using a mobile phone,

or near any other device or facility that could be interfering with signal reception?

❑ Is the antenna to the left of the display wet or covered with a sticker?

GPS Measurement Troubleshooting

1. When poor measurement conditions are due to objects blocking you from the sky or satellite pattern configuration. ➜ Change to another location or try again later.

LIGHT MENU GPS

2. When your current measurement point is more than 300km from your last measurement point. ➜Change the area setting of the watch. If you cannot find a pre-

programmed area that is close to your current position, manually input your current location.

3. After you have replaced the battery or removed and then reloaded the battery. ➜If the watch cancels the measurement operation before it can be

completed, try again. If you cannot achieve a successful measurement after about five minutes, cancel the current measurement and try again.

4. After you have not performed a GPS measurement for a long time. ➜If the watch cancels the measurement operation before it can be

completed, try again.

Getting Back to the Timekeeping Mode Screen

If you find yourself at a screen from which you do not know how to return, perform the following steps until you get back to the Timekeeping Mode or Alarm Mode. First try step 1. If that doesn’t work, advance to step 2. If you still are not in the Timekeeping Mode or Alarm Mode, perform step 3. Step 1: Press the GPS button. Step 2: Simultaneously press the LIGHT, MENU, and GPS buttons, and then

press the GPS button again.

Step 3: Press the L button twice, and then press the GPS button.

• After you get to the Timekeeping Mode, press the MENU button and

confirm that the Menu Screen appears.

• From the Menu Screen, press the GPS button to return to the Timekeeping

Mode.
