WARRANTY

14.1

One Year Limited Warranty

RC Electronics, Inc. warrants Watt's Up to be free of defects in materials and 
craftsmanship for a period of twelve months from the original date of purchase to the 
original retail purchaser.

Evidence of original purchase will be required to obtain warranty service.

RC Electronics, Inc. makes no other warranties, expressed or implied, including without 
limitation the implied warranties of merchantability and fitness for a particular purpose, 
regarding the product. RC Electronics, Inc. does not warrant, guarantee or make any 
representations regarding, currentness, or otherwise.  

In the event that the Watt's Up does not conform to this warranty at any time during the 
warranty period RC Electronics, Inc. will, at its sole discretion, repair or replace the 
defective unit with an identical unit or one of equal capabilities without charge (except 
shipping and handling). To return a unit during the warranty period, see the directions in 
the “Procedure for Warranty Claims and Return Authorization” section.

14.2

Limits and Exclusions

The warranty is valid only if the Watt's Up is operated in strict compliance with 
specifications, instructions and warnings provided in this user’s manual.

Watt's Up is not intended for industrial use.

This Warranty is invalid if the product is:

(i)

Damaged as a result of use by anyone other than as detailed in this user’s manual.

(ii) Damaged as a result of exceeding the device's ratings, prolonged reverse polarity on 

SOURCE or LOAD wires abuse, misuse, or neglect.

(iii) Damaged as a result of improper installation or usage.
(iv) Damage from immersion or cleaning with other than the described procedure.
(v) Damaged as a consequence of any repair, modification, alteration or conversion not 

performed by RC Electronics, Inc..

This warranty is void outside the United States of America and Canada.

14.3

Limitation of Liability

(i)

Specifications are subject to change without notice.

(ii) Any and all of RC Electronics, Inc. liability for actual damages from any cause whatsoever, 

and regardless of the form of the action (whether in contract, tort [including negligence], 
product liability or otherwise), will be limited to the amount actually paid for the product. 
Where the exclusion of implied warranties is not permitted by some jurisdictions the above 
exclusion may not apply.

(iii) In no event will RC Electronics, Inc., their directors, officers, employees, or agents be liable

for any harm, consequential, incidental, third party, special or indirect damages whatsoever 
(including damages for loss of business profits, business interruption, loss of business 
information, and the like) arising out of the use or inability to use the product even if RC 
Electronics, Inc. has been advised of the possibility of such damages. Because some 
jurisdictions do not allow the exclusion or limitation of liability for consequential or 
incidental damages, the above limitations may not apply.

14.4

NATURE WHATSOEVER, WHETHER EXPRESS, IMPLIED OR ARISING BY 
OPERATION OF LAW, INCLUDING, BUT NOT LIMITED TO ANY IMPLIED 
WARRANTIES OF FITNESS OR MERCHANTABILITY FOR A PARTICULAR 
PURPOSE.
