second wireless adapter, or you have a wired 
connection. 
During a wireless projection session the 
WLAN adapter is unplugged or

before ending projection. Yo u can quit the 
wireless projection immediately by selecting the 
Wireless button on the remote controller.

							Appendix E. Lenovo Statement of Limited Warranty LSOLW-00 
05/2005 
Part 1 - General Terms 
This Statement of Limited Warranty includes Part 1 - General Terms, Part 2 - 
Country-unique Terms, and Part 3 - Warranty Information. The terms of Part 2 replace or 
modify those of Part 1. The warranties provided by Lenovo Group Limited or one of its 
subsidiaries (called ″Lenovo″) in this Statement of Limited Warranty apply only to 
Machines you purchase for your use, and not for resale. The term “Machine” means a 
Lenovo machine, its options, features, conversions, upgrades or peripheral products, or any 
combination of them. The term “Machine” does not include any software programs, 
whether pre-loaded with the Machine, installed subsequently or otherwise. Nothing in this 
Statement of Limited Warranty affects any statutory rights of consumers that 
cannot be waived or limited by contract. 
What this Warranty Covers 
Lenovo warrants that each Machine 1) is free from defects in materials and 
workmanship and 2) conforms to Lenovo’s Official Published Specifications 
(“Specifications”) which are available on request. The warranty period for the 
Machine starts on the original date of installation and is specified in Part 3 - 
Warranty Information. The date on your invoice or sales receipt is the date of 
installation unless Lenovo or your reseller informs you otherwise. Unless Lenovo 
specifies otherwise, these warranties apply only in the country or region in which 
you purchased the Machine. 
THESE WARRANTIES ARE YOUR EXCLUSIVE WARRANTIES AND REPLACE 
ALL OTHER WARRANTIES OR CONDITIONS, EXPRESS OR IMPLIED, 
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OR 
CONDITIONS OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 
PURPOSE. SOME STATES OR JURISDICTIONS DO NOT ALLOW THE 
EXCLUSION OF EXPRESS OR IMPLIED WARRANTIES, SO THE ABOVE 
EXCLUSION MAY NOT APPLY TO YOU. IN THAT EVENT, SUCH 
WARRANTIES ARE LIMITED IN DURATION TO THE WARRANTY PERIOD. 
NO WARRANTIES APPLY AFTER THAT PERIOD. SOME STATES OR 
JURISDICTIONS DO NOT ALLOW LIMITATIONS ON HOW LONG AN 
IMPLIED WARRANTY LASTS, SO THE ABOVE LIMITATION MAY NOT 
APPLY TO YOU. 
What this Warranty Does not Cover 
This warranty does not cover the following: 
v 
 
 any software programs, whether pre-loaded or shipped with the Machine, or 
installed subsequently; 
v 
 
 failure resulting from misuse, accident, modification, unsuitable physical or 
operating environment, or improper maintenance by you; 
v 
 
 failure caused by a product for which Lenovo is not responsible; and 
v 
 
 any non-Lenovo products, including those that Lenovo may procure and provide 
with or integrate into a Lenovo Machine at your request.
The
 warranty is voided by removal or alteration of identification labels on the 
Machine or its parts. 
Lenovo does not warrant uninterrupted or error-free operation of a Machine.

							Any technical or other support provided for a Machine under warranty, such as 
assistance with how-to questions and those regarding Machine set-up and 
installation, is provided WITHOUT WARRANTIES OF ANY KIND. 
How to Obtain Warranty Service 
Warranty service may be provided by Lenovo, IBM, your reseller if authorized to 
perform warranty service, or an authorized warranty service provider. Each of 
them is referred to as a “Service Provider.” 
If the Machine does not function as warranted during the warranty period, contact 
a Service Provider. If you do not register the Machine with Lenovo, you may be 
required to present proof of purchase as evidence of your entitlement to warranty 
service. 
What Lenovo Will Do to Correct Problems 
When you contact a Service Provider for service, you must follow the problem 
determination and resolution procedures that we specify. An initial diagnosis of 
your problem can be made either by a technician over the telephone or 
electronically by access to a support website. 
The type of warranty service applicable to your Machine is specified in Part 3 - 
Warranty Information. 
Yo u are responsible for downloading and installing designated software updates 
from a support web site or from other electronic media, and following the 
instructions that your Service Provider provides. Software updates may include 
basic input/output system code (called “BIOS”), utility programs, device drivers, 
and other software updates. 
If your problem can be resolved with a Customer Replaceable Unit (“CRU”) (e.g., 
keyboard, mouse, speaker, memory, hard disk drive), your Service Provider will 
ship the CRU to you for you to install. 
If the Machine does not function as warranted during the warranty period and 
your problem cannot be resolved over the telephone or electronically, through your 
application of software updates, or with a CRU, your Service Provider, will either, 
at its discretion, 1) repair it to make it function as warranted, or 2) replace it with 
one that is at least functionally equivalent. If your Service Provider is unable to do 
either, you may return the Machine to your place of purchase and your money will 
be refunded. 
As part of the warranty service, your Service Provider may also install selected 
engineering changes that apply to the Machine. 
Exchange of a Machine or Part 
When the warranty service involves the exchange of a Machine or part, the item 
your Service Provider replaces becomes Lenovo’s property and the replacement 
becomes yours. Yo u represent that all removed items are genuine and unaltered. 
The replacement may not be new, but will be in good working order and at least 
functionally equivalent to the item replaced. The replacement assumes the 
warranty service status of the replaced item. 
Your Additional Responsibilities 
Before your Service Provider exchanges a Machine or part, you agree to remove all 
features, parts, options, alterations, and attachments not under warranty service. 
 
E-2 C400 Wireless Projector: User ’s Guide 
						

							Yo u also agree to: 
1.   
 ensure that the Machine is free of any legal obligations or restrictions that 
prevent its exchange; 
2. 
 
 obtain authorization from the owner to have your Service Provider service a 
Machine that you do not own; and 
3. 
 
 where applicable, before service is provided: 
a. 
 
 follow the service request procedures that your Service Provider provides; 
b. 
 
 backup or secure all programs, data, and funds contained in the Machine; 
and 
c. 
 
 provide your Service Provider with sufficient, free, and safe access to your 
facilities to permit Lenovo to fulfill its obligations.
4.
   
 (a) ensure all information about identified or identifiable individuals (Personal 
Data) is deleted from the Machine (to the extent technically possible), (b) allow 
your Service Provider or a supplier to process on your behalf any remaining 
Personal Data as your Service Provider considers necessary to fulfill its 
obligations under this Statement of Limited Warranty (which may include 
shipping the Machine for such processing to other service locations around the 
world), and (c) ensure that such processing complies with any laws applicable 
to such Personal Data.
Limitation
 of Liability 
Lenovo is responsible for loss of, or damage to, your Machine only while it is 1) in 
your Service Provider’s possession or 2) in transit in those cases where Lenovo is 
responsible for the transportation charges. 
Neither Lenovo nor your Service Provider are responsible for any of your 
confidential, proprietary or personal information contained in a Machine which 
you return for any reason. Yo u should remove all such information from the 
Machine prior to its return. 
Circumstances may arise where, because of a default on Lenovo’s part or other 
liability, you are entitled to recover damages from Lenovo. In each such instance, 
regardless of the basis on which you are entitled to claim damages from Lenovo 
(including fundamental breach, negligence, misrepresentation, or other contract or 
tort claim), except for any liability that cannot be waived or limited by applicable 
laws, Lenovo is liable for no more than 
1.   
 damages for bodily injury (including death) and damage to real property and 
tangible personal property for which Lenovo is legally liable; and 
2. 
 
 the amount of any other actual direct damages, up to the charges for the 
Machine that is subject of the claim.
This
 limit also applies to Lenovo’s suppliers, resellers and your Service Provider. It 
is the maximum for which Lenovo, its suppliers, resellers, and your Service 
Provider are collectively responsible. 
UNDER NO CIRCUMSTANCES IS LENOVO, ITS SUPPLIERS, RESELLERS OR 
SERVICE PROVIDERS LIABLE FOR ANY OF THE FOLLOWING EVEN IF 
INFORMED OF THEIR POSSIBILITY: 1) THIRD PA RT Y CLAIMS AGAINST 
YOU FOR DAMAGES (OTHER THAN THOSE UNDER THE FIRST ITEM 
LISTED ABOVE); 2) LOSS OF, OR DAMAGE TO, D ATA ; 3) SPECIAL, 
INCIDENTAL, OR INDIRECT DAMAGES OR FOR ANY ECONOMIC 
CONSEQUENTIAL DAMAGES; OR 4) LOST PROFITS, BUSINESS REVENUE, 
GOODWILL OR ANTICIPATED SAVINGS. SOME STATES OR 
JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF 
INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE 
LIMITATION OR EXCLUSION MAY NOT APPLY TO YOU.
