Limited One Year Warranty

Limited One Year Warranty

COBRA ELECTRONICS CORPORATION 

warrants that its COBRA

CB Transceiver, and the component parts thereof, will be free of
defects in material and workmanship for a period of one (1) year
from the date of consumer purchase. This warranty may be
enforced by the first consumer purchaser, provided that the
product is utilized within the U.S.A.

COBRA will, without charge, repair or replace, at its option, a
defective CB Transceiver upon delivery to the COBRA factory
Service Department, accompanied by proof of the date of first
consumer purchase, such a duplicated sales receipt.

You must pay initial shipping charges required to ship the
product for warranty service, but the return charges will be at
COBRA’S expense, if the product is repaired or replaced under
warranty.

This warranty gives you specific legal rights, and you may also
have other rights which vary from state to state.

Exclusions:

This limited warranty does not apply;

1) to any product damaged by accident;
2) in the event of misuse or abuse of the product or as a result of
unauthorized alterations or repairs;
3) if the serial number has been altered, defaced or removed; 4) if
the owner of the product resides outside the U.S.A.

All implied warranties, including warranties of merchantability
and fitness for a particular purpose are limited in duration to
the length of this warranty.

COBRA shall not be liable for any incidental, consequential or
other damages; including, without limitation, damages
resulting from loss of use or cost of installation.

Some states do not allow limitations on how long an implied
warranty lasts and/or do not allow the exclusion or limitation of
incidental or consequential damages, so the above limitations
may not apply to you.
