Before Getting

Started...

This section provides an overview of your watch and explains how to connect with a phone. You can configure watch settings to connect with a phone at preset times each day and adjust its time settings in accordance with information obtained from a network time server. You can also change the watch’s time settings manually and configure other watch settings from the phone.

Important!

●

This watch is not a special-purpose measuring instrument. Measurement function readings are intended for general reference only.

●

The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure readings produced by its pressure sensor. Because of this, altitude values displayed by the watch may be different from your actual elevation and/or sea level elevation indicated for the area where you are located. Regular calibration in accordance with the local altitude (elevation) indications is recommended.

Altitude Measurement

●

Whenever using the Digital Compass of this watch for serious trekking, mountain climbing, or other activities, be sure always to take along another compass to confirm readings. If the readings produced by the Digital Compass of this watch are different from those of the other compass, perform 3-point calibration of the Digital Compass to ensure better accuracy.

ー

Compass readings and calibration

will not be possible if the watch is in the vicinity of a permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or electrical household appliances (TV, computer, cellphone, etc.)

Digital Compass

●

Some of the functions of this watch cannot be used unless it is connected with a phone. You should also leave the phone’s location information setting turned on. Otherwise, the phone will not be able to acquire latitude and longitude information, which may cause the watch to display incorrect information.

●

Charging the Watch

Solar Charging

Power generated by the solar panel powers watch operations and also is used to charge a rechargeable (secondary) battery. The solar panel is integrated into the LCD of the watch, and power for charging is generated whenever the face is exposed to light.

●

Charging the Watch

When you are not wearing the watch, put it in a location where it is exposed to bright light.

While you are wearing the watch, make sure that its LCD (solar panel) is not blocked from the light by the sleeve of your clothing. Power generation efficiency is reduced even when the LCD is blocked only partially.

Important!

Charging with the Charger

Charging with the charger is faster than solar charging.

Important!

●

Use only the supplied charger and USB cable for charging.

●

A device with a USB port (Type-A) can also be used for charging.

●

Note that no guarantees are made concerning the suitability of all types of USB ports for charging. If charging is not possible for some reason, disconnection from the USB port is recommended.

●

Place the charger on a desk or other stable surface, making sure there is plenty of open space around it. Charging with the charger and watch in a bag or some other enclosed space can cause overheating of the watch and/or charger.

●

Should water or any other liquid get onto the watch or charger during charging, immediately disconnect the USB cable from the power source.

●

The charger unit is not waterproof. Avoid use in areas where moisture or high humidity is present.

●

Perform charging in an environment where ambient temperature is between 5°C and 35°C (41°F and 95°F).

●

Depending on light intensity and local conditions, the watch may become hot

Precautions When Charging

●

GPS signals (for time adjustment, log acquisition, point memory, etc.) are not received while charging with the charger is in progress.

●

The watch’s GPS function will not be able to be used for about one minute after you remove it from the charger. During that period the watch also will not be able to detect whether it is connected to or disconnected from the charger.

●

Do not attempt charging at high ambient temperatures of 35°C or greater. The watch becomes hot during charging, which will cause charging to stop. High ambient temperature may result in a less than full charge.

●

Do not carry the charger in a bag or otherwise subject it to squeezing or crushing forces. Doing so can cause deformation of the claws so they become open too far, making it impossible to attach the watch to the charger.

●

If an ongoing charging operation stops, remove the watch from the charger and disconnect the USB cable. After checking for and eliminating problems, try charging again.

●

It may take some time for charging to start after the watch is attached to the charger.

●

Digital Compass Reading Precautions

Location During Use

Taking readings near sources of strong magnetism can cause reading error. Keep the watch away from the following types of items.

Permanent magnets (magnetic accessories, etc.), metal objects, high-voltage wires, aerial wires, electrical household appliances (TVs, computers, cellphones, etc.)

●

Note that correct direction readings are not possible indoors, especially inside of reinforced concrete structures.

●

Accurate direction readings are not possible in motor vehicles, on boats, on aircraft, etc.

Storage Location

Exposure of the watch to magnetism can affect the accuracy of digital compass readings. Keep the watch away from the types of items below.

Permanent magnets (magnetic accessories, etc.), metal objects, electrical household appliances (TVs, computers, cellphones, etc.)

Altitude Measurement

The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor.

Important!

●

The altitude readings displayed by the watch are relative values that are calculated based on barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes due to weather can cause altitude readings taken at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/ or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, it is recommended that you regularly calibrate its readings in accordance with local altitude (elevation) indications.

Calibrating Altitude Readings

●

When using navigation while receiving GPS signals, measured altimeter values are automatically adjusted in accordance with GPS signal data. Note, however, that this may result in some difference between the measured value and the actual altitude. Also note that the measured altitude value adjustment operation using GPS signal data may take a few minutes. The adjustment operation may take even longer, depending on your current environment. Regular manual adjustment of the measured altitude value using locally available information is recommended. The watch will not use GPS signal data to adjust measured altitude values for one hour after you adjustment the measured altitude value manually.

●

The altitude correction value and barometric pressure changes may result in display of a negative value.

●

Check the information below to find out about how to minimize differences between readings produced by the watch, and values provided by local altitude (elevation) indications.

your current location’s altitude as the reference altitude.

This makes the altitude differential ±0 m (±0 feet).

While comparing the difference between

the altitude you found on the map and the altitude differential displayed by the watch, advance towards your destination.

●

When the altitude differential you found on the map is the same as that displayed by the watch, it means you are close to your destination.

Note

●

In place of step 3 of the above procedure, you could perform the steps below to make the altitude differential ±0 m (±0 feet).

Press (A).

Rotate the rotary switch to move the

Press the rotary switch. This makes the altitude differential ±0 m (±0 feet).

●

[-----] will appear on the display when a reading is outside the allowable altitude measurement range (±3,000 m (±9,840 feet)), or if a measurement error occurs.

Calibrating Altitude Readings

To minimize the difference between locally indicated and measured values, you should update the reference altitude value before setting off on and during treks or any other activities where you take altitude readings. You can find out the altitude at your current location from signs, maps, on the Internet, etc. While mountain climbing, it is highly recommended that you check a map, local altitude indications, or some other source for your current location’s altitude and regularly calibrate watch readings with the latest information.

●

Differences between actual altitude and watch readings can be caused by the factors below.

ー

Changes in barometric pressure

ー

Changes in temperature caused by

variations in barometric pressure and by elevation

Barometric Pressure Reading Precautions

●

The barometric pressure graph produced by this watch can be used to obtain an idea of upcoming weather conditions. However, this watch should not be used in place of precision instruments required for official weather prediction and reporting.

●

Pressure sensor readings can be affected by sudden changes in temperature. Because of this, there may be some error in the readings produced by the watch.

●

Temperature Reading Precautions

Body temperature, direct sunlight, and humidity all have an effect on temperature readings. To help ensure more accurate temperature readings, remove the watch from your wrist, wipe it dry of any moisture, and place it in a well-ventilated location not exposed to direct sunlight. You should be able to take temperature readings after about 20 to 30 minutes.

Altitude Measurement

Readings produce different results at

the same location. Watch readings are different from altitude information available from other sources. Correct altitude readings are not possible.

Relative altitude is calculated based on changes in barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, it is recommended that you regularly calibrate its readings in accordance with local altitude (elevation) indications.

Calibrating Altitude Readings

[-----] appears on the display

following altitude differential measurement.

[-----] appears when the altitude differential is outside the allowable measuring range (±3,000 m). If [ERROR] appears on the display, there may be a problem with the sensor.
