❏Disassembling or remodeling the device
❏Removing the verication or certication number for the device
Frequency
is device uses the frequency bands 2.402 to 2.480 GHz. Other wireless devices may
use the same frequency. Note the following points to avoid wireless interference with
other wireless devices.
Precautions when performing wireless communication
is device operates on the 2.4 GHz band.
is device operates in the same frequency bandwidth as industrial, scientic, and medical devices such as
microwave ovens and mobile object identication (RF-ID) systems (licensed premises radio stations, amateur, and
unlicensed specied low-power radio stations (hereaer "other radio stations")) used in factory production lines.
1. Before using this device, make sure there are no "other radio stations" being used in the vicinity.
2. If this device causes RF interference between the device and "other radio stations", promptly move to a dierent

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

electronic
interference, such
as constructions

Near high-voltage

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-57 User Manual
Setup

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 33
❏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
minutes
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 Wal k .

You can check the estimated VO2max on Epson View. Refer to the following website for more information.

What is VO2max
VO2max is the maximum amount of oxygen that a person can take per kilogram for one minute. Based on the
estimated VO2max, your time of 5km race, 10km race, half marathon, or full marathon can be estimated.
To estimate VO2max, running is required with the following conditions satised.
❏You prole information (such as body height, weight, and gender) has been
correctly entered.
❏Select [Run] as the activity type (Estimation is not available with [Walk] 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 26
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.
