WARRANTY
THREE YEAR LIMITED WARRANTY
R.L. DRAKE COMPANY warrants to the original purchaser this product shall be free from defects in material or
workmanship for three (3) years from the date of original purchase.
During the warranty period the R.L. DRAKE COMPANY or an authorized Drake service facility will provide, free of charge,
both parts and labor necessary to correct defects in material and workmanship. At its option, R.L. DRAKE COMPANY
may replace a defective unit.
To obtain such warranty service, the original purchaser must:
(1) Retain invoice or original proof of purchase to establish the start of the warranty period.
(2) Notify the R.L. DRAKE COMPANY or the nearest authorized service facility, as soon as possible after discovery
of a possible defect, of:
(a) the model and serial number,
(b) the identity of the seller and the approximate date of purchase; and
(c) A detailed description of the problem, including details on the electrical connection to associated equipment and the
list of such equipment.
(3) Deliver the product to the R.L. DRAKE COMPANY or the nearest authorized service facility, or ship the same in
its original container or equivalent, fully insured and shipping charges prepaid.
Correct maintenance, repair, and use are necessary to obtain proper performance from this product. Therefore carefully
read the Instruction Manual. This warranty does not apply to any defect that R.L. DRAKE COMPANY determines is
due to:
(1) Improper maintenance or repair, including the installation of parts or accessories that do not conform to the quality
and specifications of the original parts.
(2) Misuse, abuse, neglect or improper installation.
(3) Accidental or intentional damage.
All implied warranties, if any, including warranties of merchantability and fitness for a particular purpose, terminate three
(3) years from the date of the original purchase.
The foregoing constitutes R.L. DRAKE COMPANY'S entire obligation with respect to this product, and the original
purchaser shall have no other remedy and no claim for incidental or consequential damages, losses or expenses. Some
states do not allow limitations on how long an implied warranty lasts or do not allow the exclusions or limitation of incidental
or consequential damages, so the above limitation and exclusion may not apply to you.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state. This
warranty shall be construed under the laws of Ohio.
