Device sensors

GPS signal reception (GPS positioning)

GPS positioning

GPS positioning is the process by which the device receives a GPS signal and timing information to measure routes, distance, pace, and other information.

To ensure accuracy of measurements, use the device under the following conditions in areas of good GPS signal reception.

Scenarios in which GPS positioning is used

❏ GPS measuring (Run or Walk measurements)

❏ Time synchronization (SETTINGSSet by GPS, SystemUpdate Time)

Good signal reception conditions

Locations where you cannot receive signals Locations that are

dicult

to receive signals

Inside rooms or buildings, or underground

In tunnels Under water Locations with

electronic interference, such as constructions sites and heavy trac

Near high-voltage wires or television towers, overhead electric wires for trains, and roads with skyscrapers

On water

Using the device for the

rst

time

Before using the device for the rst time aer purchase, wait at least 15 minutes aer initial GPS positioning outdoors with no obstructions overhead while the device displays the Measurement screen. is improves measurement accuracy.

J-347/367, U-350 User Manual

Setup

Page 28

The Measurement screen appears after GPS locating.

Wait 15 minutes

Note

❏ Refer to the following page for more information on GPS positioning.

U “Measurement preparation (selecting the Activity Type)” on page 36

❏ is process normally only needs to be performed once.

❏ Perform this process if the device has not been used for several months.

Note

e basic conguration of the GPS system is 24 satellites orbiting the Earth at an altitude of 20,000 km with at least four satellites traveling in six dierent orbits. e GPS receiver acquires data from four satellites and calculates the latitude, longitude, altitude, and time. You can start measuring once the GPS positioning has been performed and this information has been received. You can receive more detailed GPS navigation data (satellite orbital information) if you wait 15 minutes aer initial GPS signal acquisition, which improves measuring accuracy.

However, note that GPS positioning is not 100% accurate or reliable at all times even with the more detailed GPS data because of atmospheric conditions and the usage environment.

Note AGPS - Reducing the GPS Positioning Time

You can reduce the GPS signal acquisition time by connecting the device with a smartphone and then retrieving GPS satellite information from a network server. Refer to the Epson View website for more information.

About the stride sensor

is device is equipped with a stride sensor. is sensor enables the device to continue measuring your distance and pace in locations with poor GPS signal reception, such as in tunnels or indoors.

Using the device for the rst time

When using the device for the rst time, run or walk for the specied time depending on the location as described in the following table to allow the device to acclimate to your stride.

Location Time

Outside with no obstructions overhead

Approx. 10 minutes

Area with many buildings Approx. 30

Note

❏ is process normally only needs to be performed once. However, note that information on your stride is initialized if

the device is initialized. If this occurs, you need to perform the process to allow the stride sensor to acclimate to your stride again.

❏ When you mainly use the device for walking, set the activity type to Wa l k .

Problem Solution

GPS GPS signal reception is weak or

failing.

Perform GPS positioning again with the device outside with no obstructions overhead for 15 minutes.

U “GPS signal reception (GPS positioning)” on page 27

Go to a location outside with no obstructions overhead. GPS signals cannot be received while indoors. Obstacles partially blocking the sky, such as tall buildings and mountain sides, can also interrupt signal reception, which results in reduced distance accuracy.

GPS signal reception is weak or interrupted.

Even when a signal is being received, it may be interrupted depending on the running environment.

Wear the device on the outside of your arm. Also, make sure the strap is tightened.

Charging The device does not charge after

attaching the USB Charging clip.

Check the USB Charging clip connection.

Clean the contact points of the device and USB Charging clip.

U “Main device and band” on page 80

❏ The charge screen may not appear for 1 to 2 minutes after

attaching the USB Charging clip when the battery is completely exhausted. This is not a malfunction.

❏ A malfunction may have occurred if you cannot charge the

device even after checking the points above. If this happens, immediately stop trying to charge the device and send the main device and USB Charging clip to our repair center.

The charge error screen is displayed.

Charge in environments with ambient temperatures of 5 to 35˚C.

The main device and USB Charging clip become hot during the charging process.

There may be a malfunction. Stop charging the device immediately and contact our repair center.

Water resistance Can I use the device when

swimming?

This device is water resistant up to 5 bars of pressure and can be used while swimming. However, do not press any buttons while the device is underwater. The device cannot receive GPS signals while underwater.

The inside of the glass becomes cloudy.

Condensation may occur in the device due to dierences in temperature between the device and the open air. Temporary condensation does not have any
