Acquiring a GPS Signal
To ensure the accuracy of the measurements taken by your watch, you must position yourself to acquire
a strong GPS signal. GPS positioning allows your watch to receive a GPS signal and timing information
so it can correctly track your routes, distance, pace, and other workout and activity data.
For increased GPS accuracy, wait at least 15 minutes before starting your workout. You only need to
perform this extended GPS calibration the first time you use the watch or if you do not use it for a few
months.
Note: To reduce the time it takes to locate the GPS signal, you can use the AGPS feature in the Epson
View app on your smartphone. If you keep your watch connected to your smartphone, your watch
automatically downloads GPS updates once an hour.
When positioning yourself to acquire a GPS signal, avoid the following environments:
• Inside buildings or rooms, or underground areas or tunnels
• Near high-voltage wires, television towers, tall buildings, tall trees, or overhead electrical wires for
trains or buses
• Locations with concentrated electronic interference, such as construction sites and heavy traffic
• Under water or floating on water
If you have issues acquiring a signal, move into as open an area as possible. If you still cannot acquire a
signal, select Skip on the GPS screen to start your workout. Distance traveled will be estimated based
on your stride until the GPS signal is fully acquired.

Measuring Your Heart Rate
Your watch includes a sensor on the back to detect your heart rate.
Caution: The sensor light causes no adverse effects on your skin, but you should not look directly at the
light.
Wear the product snugly around your wrist as shown. Tighten the watch if your heart rate is not
measured correctly.
Note: Do not wear the product too tight. You should still be able to fit your little finger under the watch
band. If you feel any discomfort, loosen the wristband.
30
Note: Do not wear the watch on the underside of your wrist or covering the ulna bone.
Once the watch has detected your heart rate, it displays your heart rate, heart rate zone, and the HR
icon on the Time screen.
Note: When using your watch in Pool Swim or Open Water mode, it does not display your heart rate in
real time.
You can also press theUp button to display the Heart Rate screen.
31
Note: If you see ––– on the display or the HR icon is flashing, the watch has not detected your heart
rate. Make sure you are wearing the watch correctly and try again. If your heart rate often reads less
than 120 beats while running or 70 beats while walking, you may have a naturally low heart rate. This
can cause incorrect heart rate measurements. Set the HR Measurement option to Settings 2 in the
Epson View app to correct the issue.

Calculating Your Stride Length
Your watch automatically calculates your stride length so it can accurately measure distance and pace
data in locations with poor GPS signal reception, such as indoors or in tunnels.

You can also run or walk between tall buildings or trees for at least 30 minutes. This allows your watch to
learn your normal stride length. You should only need to perform this step once.
Note: Do not cross your arms or hold onto the treadmill handles or the stride sensor may not detect your
movement.

Estimating VO2Max
Your watch calculates the estimated maximum quantity of oxygen that your body can process, called
VO2max. This estimate can be an indicator of your fitness level and should increase with improved
athletic performance.
Your watch uses your heart rate and GPS measurements to accurately calculate the VO2max under the
following conditions:
• Your profile information must be set up correctly.
VO2max is only measured in Run Mode.
• Your watch is connected to GPS and you run with the watch for at least 10 minutes.
49
• You turned on heart rate measurement and the AT Pause setting is turned off.
• Your running pace is 16 min/mile (10 min/km) or faster.
• You are running at an elevated heart rate at moderate intensity.
Your watch cannot accurately estimate the VO2max if the following occurs:
• You stop running before 10 minutes have elapsed.
• Your heart rate cannot be measured.
• Your running speed slowed to a walk or you stopped for a traffic signal, and your heart rate dropped
too low for estimation.

Binding Arbitration and Class Waiver
1. DISPUTES, BINDING INDIVIDUAL ARBITRATION, AND WAIVER OF CLASS ACTIONS AND
CLASS ARBITRATIONS
1.1 Disputes. The terms of this Section 1 shall apply to all Disputes between you and Epson. The term
"Dispute" is meant to have the broadest meaning permissible under law and includes any dispute, claim,
controversy or action between you and Epson arising out of or relating to this Agreement, Epson
branded products (hardware and including any related software), or other transaction involving you and
Epson, whether in contract, warranty, misrepresentation, fraud, tort, intentional tort, statute, regulation,
ordinance, or any other legal or equitable basis. "DISPUTE" DOES NOT INCLUDE IP CLAIMS, or more
specifically, a claim or cause of action for (a) trademark infringement or dilution, (b) patent infringement,
(c) copyright infringement or misuse, or (d) trade secret misappropriation (an "IP Claim"). You and Epson
also agree, notwithstanding Section 1.6,that a court, not an arbitrator, may decide if a claim or cause of
action is for an IP Claim.
1.2 Binding Arbitration. You and Epson agree that all Disputes shall be resolved by binding arbitration
according to this Agreement. ARBITRATION MEANS THAT YOU WAIVE YOUR RIGHT TO A JUDGE
83
OR JURY IN A COURT PROCEEDING AND YOUR GROUNDS FOR APPEAL ARE LIMITED.
Pursuant to this Agreement, binding arbitration shall be administered by JAMS, a nationally recognized
arbitration authority, pursuant to its code of procedures then in effect for consumer related disputes, but
excluding any rules that permit joinder or class actions in arbitration (for more detail on procedure, see
Section 1.6 below). You and Epson understand and agree that (a) the Federal Arbitration Act (9 U.S.C.
§1, et seq.) governs the interpretation and enforcement of this Section 1, (b) this Agreement
memorializes a transaction in interstate commerce, and (c) this Section 1 shall survive termination of this
Agreement.
1.3 Pre-Arbitration Steps and Notice. Before submitting a claim for arbitration, you and Epson agree to
try, for sixty (60) days, to resolve any Dispute informally. If Epson and you do not reach an agreement to
resolve the Dispute within the sixty (60) days), you or Epson may commence an arbitration. Notice to
Epson must be addressed to: Epson America, Inc., ATTN: Legal Department, 3840 Kilroy Airport Way,
Long Beach, CA 90806 (the "Epson Address"). The Dispute Notice to you will be sent to the most recent
address Epson has in its records for you. For this reason, it is important to notify us if your address
changes by emailing us at EAILegal@ea.epson.com or writing us at the Epson Address above. Notice of
the Dispute shall include the sender's name, address and contact information, the facts giving rise to the
Dispute, and the relief requested (the "Dispute Notice"). Following receipt of the Dispute Notice, Epson
and you agree to act in good faith to resolve the Dispute before commencing arbitration.
1.4 Small Claims Court. Notwithstanding the foregoing, you may bring an individual action in the small
claims court of your state or municipality if the action is within that court's jurisdiction and is pending only
in that court.
1.5 WAIVER OF CLASS ACTIONS AND CLASS ARBITRATIONS. YOU AND EPSON AGREE THAT
EACH PARTY MAY BRING DISPUTES AGAINST THE OTHER PARTY ONLY IN AN INDIVIDUAL
CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS OR
REPRESENTATIVE PROCEEDING, INCLUDING WITHOUT LIMITATION FEDERAL OR STATE
CLASS ACTIONS, OR CLASS ARBITRATIONS. CLASS ACTION LAWSUITS, CLASS-WIDE
ARBITRATIONS, PRIVATE ATTORNEY-GENERAL ACTIONS, AND ANY OTHER PROCEEDING
WHERE SOMEONE ACTS IN A REPRESENTATIVE CAPACITY ARE NOT ALLOWED.
ACCORDINGLY, UNDER THE ARBITRATION PROCEDURES OUTLINED IN THIS SECTION, AN
ARBITRATOR SHALL NOT COMBINE OR CONSOLIDATE MORE THAN ONE PARTY'S CLAIMS
WITHOUT THE WRITTEN CONSENT OF ALL AFFECTED PARTIES TO AN ARBITRATION
PROCEEDING.
1.6 Arbitration Procedure. If you or Epson commences arbitration, the arbitration shall be governed by
the rules of JAMS that are in effect when the arbitration is filed, excluding any rules that permit arbitration
on a class or representative basis (the "JAMS Rules"), available at http://www.jamsadr.com or by calling
1-800-352-5267, and under the rules set forth in this Agreement. All Disputes shall be resolved by a
single neutral arbitrator, and both parties shall have a reasonable opportunity to participate in the
selection of the arbitrator. The arbitrator is bound by the terms of this Agreement. The arbitrator, and not
any federal, state or local court or agency, shall have exclusive authority to resolve all disputes arising
84
out of or relating to the interpretation, applicability, enforceability or formation of this Agreement,
including any claim that all or any part of this Agreement is void or voidable. Notwithstanding this broad
delegation of authority to the arbitrator, a court may determine the limited question of whether a claim or
cause of action is for an IP Claim, which is excluded from the definition of "Disputes" in Section 1.1
above. The arbitrator shall be empowered to grant whatever relief would be available in a court under
law or in equity. The arbitrator may award you the same damages as a court could, and may award
declaratory or injunctive relief only in favor of the individual party seeking relief and only to the extent
necessary to provide relief warranted by that party's individual claim. In some instances, the costs of
arbitration can exceed the costs of litigation and the right to discovery may be more limited in arbitration
than in court. The arbitrator's award is binding and may be entered as a judgment in any court of
competent jurisdiction.
You may choose to engage in arbitration hearings by telephone. Arbitration hearings not conducted by
telephone shall take place in a location reasonably accessible from your primary residence, or in Orange
County, California, at your option.
a) Initiation of Arbitration Proceeding. If either you or Epson decides to arbitrate a Dispute, both parties
agree to the following procedure:
(i) Write a Demand for Arbitration. The demand must include a description of the Dispute and the amount
of damages sought to be recovered. You can find a copy of a Demand for Arbitration at
http://www.jamsadr.com ("Demand for Arbitration").
(ii) Send three copies of the Demand for Arbitration, plus the appropriate filing fee, to: JAMS, 500 North
State College Blvd., Suite 600 Orange, CA 92868, U.S.A.
(iii) Send one copy of the Demand for Arbitration to the other party (same address as the Dispute
Notice), or as otherwise agreed by the parties.
b) Hearing Format. During the arbitration, the amount of any settlement offer made shall not be disclosed
to the arbitrator until after the arbitrator determines the amount, if any, to which you or Epson is entitled.
The discovery or exchange of non-privileged information relevant to the Dispute may be allowed during
the arbitration.
c) Arbitration Fees. Epson shall pay, or (if applicable) reimburse you for, all JAMS filings and arbitrator
fees for any arbitration commenced (by you or Epson) pursuant to provisions of this Agreement.
d) Award in Your Favor. For Disputes in which you or Epson seeks $75,000 or less in damages exclusive
of attorney's fees and costs, if the arbitrator's decision results in an award to you in an amount greater
than Epson's last written offer, if any, to settle the Dispute, Epson will: (i) pay you $1,000 or the amount
of the award, whichever is greater; (ii) pay you twice the amount of your reasonable attorney's fees, if
any; and (iii) reimburse you for any expenses (including expert witness fees and costs) that your attorney
reasonably accrues for investigating, preparing, and pursuing the Dispute in arbitration. Except as
agreed upon by you and Epson in writing, the arbitrator shall determine the amount of fees, costs, and
expenses to be paid by Epson pursuant to this Section 1.6d).
85
e) Attorney's Fees. Epson will not seek its attorney's fees and expenses for any arbitration commenced
involving a Dispute under this Agreement. Your right to attorney's fees and expenses under Section
1.6d) above does not limit your rights to attorney's fees and expenses under applicable law;
notwithstanding the foregoing, the arbitrator may not award duplicative awards of attorney's fees and
expenses.
1.7 Opt-out. You may elect to opt-out (exclude yourself) from the final, binding, individual
arbitration procedure and waiver of class and representative proceedings specified in this
Agreement by sending a written letter to the Epson Address within thirty (30) days of your assent
to this Agreement (including without limitation the purchase, download, installation of the
Software or other applicable use of Epson Hardware, products and services) that specifies (i)
your name, (ii) your mailing address, and (iii) your request to be excluded from the final, binding
individual arbitration procedure and waiver of class and representative proceedings specified in
this Section 1. In the event that you opt-out consistent with the procedure set forth above, all
other terms shall continue to apply, including the requirement to provide notice prior to litigation.
1.8 Amendments to Section 1. Notwithstanding any provision in this Agreement to the contrary, you
and Epson agree that if Epson makes any future amendments to the dispute resolution procedure and
class action waiver provisions (other than a change to Epson's address) in this Agreement, Epson will
obtain your affirmative assent to the applicable amendment. If you do not affirmatively assent to the
applicable amendment, you are agreeing that you will arbitrate any Dispute between the parties in
accordance with the language of this Section 1 (or resolve disputes as provided for in Section 1.7, if you
timely elected to opt-out when you first assented to this Agreement).
1.9 Severability. If any provision in this Section 1 is found to be unenforceable, that provision shall be
severed with the remainder of this Agreement remaining in full force and effect. The foregoing shall not
apply to the prohibition against class or representative actions as provided in Section 1.5. This
means that if Section 1.5 is found to be unenforceable, the entire Section 1 (but only Section 1)
shall be null and void.
