PROCEDURE FOR RESOLVING DISPUTES:  
ALL DISPUTES BETWEEN YOU AND LG ARISING OUT OF OR RELATING IN ANY WAY TO THIS  
LIMITED WARRANTY OR THE PRODUCT SHALL BE RESOLVED EXCLUSIVELY THROUGH BINDING  
ARBITRATION, AND NOT IN A COURT OF GENERAL JURISDICTION. BINDING ARBITRATION  
MEANS THAT YOU AND LG ARE EACH WAIVING THE RIGHT TO A JURY TRIAL AND TO BRING OR  
PARTICIPATE IN A CLASS ACTION.  
Definitions. For the purposes of this section, references to “LG” mean LG Electronics U.S.A., Inc., its  
parents, subsidiaries and affiliates, and each of their officers, directors, employees, agents, beneficiaries,  
predecessors in interest, successors, assigns and suppliers; references to “dispute” or “claim” shall  
include any dispute, claim or controversy of any kind whatsoever (whether based in contract, tort, statute,  
regulation, ordinance, fraud, misrepresentation or any other legal or equitable theory) arising out of or  
relating in any way to the sale, condition or performance of the product or this Limited Warranty.  
Notice of Dispute. In the event you intend to commence an arbitration proceeding, you must first notify  
LG in writing at least 30 days in advance of initiating the arbitration by sending a letter to LG at LG  
Electronics, USA, Inc. Attn: Legal Department- Arbitration 111 Sylvan Avenue, Englewood Cliffs, NJ 07632.  
You and LG agree to engage in good faith discussions in an attempt to amicably resolve your claim. The  
notice must provide your name, address, and telephone number; identify the product that is the subject of  
the claim; and describe the nature of the claim and the relief being sought. If you and LG are unable to  
resolve the dispute within 30 days, either party may proceed to file a claim for arbitration.  
Agreement to Binding Arbitration and Class Action Waiver. Upon failure to resolve the dispute  
during the 30 day period after sending written notice to LG, you and LG agree to resolve any claims  
between us only by binding arbitration on an individual basis, unless you opt out as provided below. Any  
dispute between you and LG shall not be combined or consolidated with a dispute involving any other  
person’s or entity’s product or claim. More specifically, without limitation of the foregoing, any dispute  
between you and LG shall not under any circumstances proceed as part of a class or representative  
action. Instead of arbitration, either party may bring an individual action in small claims court, but that  
small claims court action may not be brought on a class or representative basis.  
Arbitration Rules and Procedures. To begin arbitration of a claim, either you or LG must make a  
written demand for arbitration. The arbitration will be administered by the American Arbitration Association  
(“AAA”) and will be conducted before a single arbitrator under the AAA’s Consumer Arbitration Rules that  
are in effect at the time the arbitration is initiated (referred to as the “AAA Rules”) and under the  
copy of your written demand for arbitration, as well as a copy of this provision, to the AAA in the manner  
described in the AAA Rules. You must also send a copy of your written demand to LG at LG Electronics,  
USA, Inc. Attn: Legal Department- Arbitration 111 Sylvan Avenue, Englewood Cliffs, NJ 07632. If there is a  
conflict between the AAA Rules and the rules set forth in this section, the rules set forth in this section will  
govern. This arbitration provision is governed by the Federal Arbitration Act. Judgment may be entered on  
the arbitrator’s award in any court of competent jurisdiction. All issues are for the arbitrator to decide,  
except that issues relating to the scope and enforceability of the arbitration provision and to the  
arbitrability of the dispute are for the court to decide. The arbitrator is bound by the terms of this provision.  
Governing Law. The law of the state of your residence shall govern this Limited Warranty and any  
disputes between us except to the extent that such law is preempted by or inconsistent with applicable  
federal law.  
28  
EN  
Fees/Costs. You do not need to pay any fee to begin an arbitration. Upon receipt of your written demand  
for arbitration, LG will promptly pay all arbitration filing fees to the AAA unless you seek more than  
$25,000 in damages, in which case the payment of these fees will be governed by the AAA Rules. Except  
as otherwise provided for herein, LG will pay all AAA filing, administration and arbitrator fees for any  
arbitration initiated in accordance with the AAA Rules and this arbitration provision. If you prevail in the  
arbitration, LG will pay your attorneys’ fees and expenses as long as they are reasonable, by considering  
factors including, but not limited to, the purchase amount and claim amount. Notwithstanding the  
foregoing, if applicable law allows for an award of reasonable attorneys’ fees and expenses, an arbitrator  
can award them to the same extent that a court would. If the arbitrator finds either the substance of your  
claim or the relief sought in the demand is frivolous or brought for an improper purpose (as measured by  
the standards set forth in Federal Rule of Civil Procedure 11(b)), then the payment of all arbitration fees  
will be governed by the AAA Rules. In such a situation, you agree to reimburse LG for all monies  
previously disbursed by it that are otherwise your obligation to pay under the AAA Rules. Except as  
otherwise provided for, LG waives any rights it may have to seek attorneys’ fees and expenses from you if  
LG prevails in the arbitration.  
Hearings and Location. If your claim is for $25,000 or less, you may choose to have the arbitration  
conducted solely on the basis of (1) documents submitted to the arbitrator, (2) through a telephonic  
hearing, or (3) by an in-person hearing as established by the AAA Rules. If your claim exceeds $25,000,  
the right to a hearing will be determined by the AAA Rules. Any in-person arbitration hearings will be held  
at a location within the federal judicial district in which you reside unless we both agree to another  
location or we agree to a telephonic arbitration.  
Opt Out. You may opt out of this dispute resolution procedure. If you opt out, neither you nor LG can  
require the other to participate in an arbitration proceeding. To opt out, you must send notice to LG no  
later than 30 calendar days from the date of the first consumer purchaser’s purchase of the product by  
either: (i) sending an e-mail to [email protected], with the subject line: “Arbitration Opt Out” or (ii) calling  
1-800-980-2973. You must include in the opt out e-mail or provide by telephone: (a) your name and  
address; (b) the date on which the product was purchased; (c) the product model name or model number;  
and (d) the serial number (the serial number can be found (i) on the product; or (ii) online by accessing  
Serial Number”).  
You may only opt out of the dispute resolution procedure in the manner described above (that is, by  
e-mail or telephone); no other form of notice will be effective to opt out of this dispute resolution  
procedure. Opting out of this dispute resolution procedure will not affect the coverage of the Limited  
Warranty in any way, and you will continue to enjoy the full benefits of the Limited Warranty. If you keep  
this product and do not opt out, then you accept all terms and conditions of the arbitration provision  
described above.
