IMPORTANT WARRANTY INFORMATION! PLEASE READ

Return Policy on Kits When Not Purchased Directly From Vectronics: Before continuing any
further with your VEC kit check with your Dealer about their return policy. If your Dealer
allows returns, your kit must be returned 

before you 

begin construction.

Return Policy on Kits When Purchased Directly From Vectronics: Your VEC kit may be
returned to the factory 

in its pre-assembled condition only. 

The reason for this stipulation is,

once you begin installing and soldering parts, you essentially take over the role of the device's
manufacturer. From this point on, neither Vectronics nor its dealers can reasonably be held
accountable for the quality or the outcome of your work. Because of this, Vectronics cannot
accept return of any kit-in-progress or completed work as a warranty item for any reason
whatsoever.

If you are a new or inexperienced kit builder, we urge you to read the

manual carefully and determine whether or not you're ready to take on the job.

If you

wish to change your mind and return your kit, you may--but you must do it 

before you 

begin

construction, and within ten (10) working days of the time it arrives.

Vectronics Warrants: Your kit contains each item specified in the parts list.

Missing Parts:

If you determine, during your pre-construction inventory, that any part is

missing, please contact Vectronics and we'll send the missing item to you free of charge.
However, 

before you 

contact Vectronics, 

please look carefully 

to confirm you haven't misread

the marking on one of the other items provided with the kit. Also, make certain an alternative
part hasn't been substituted for the item you're missing. If a specific part is no longer available,
or if Engineering has determined that an alternative component is more suitable, Vectronics
reserves the right to make substitutions at any time. In most cases, these changes will be
clearly noted in an addendum to the manual.

Defective Parts: Today's electronic parts are physically and electrically resilient, and defective
components are rare. However, if you discover an item during your pre-construction inventory
that's obviously broken or unserviceable, we'll replace it. Just return the part to Vectronics at
the address below accompanied with an explanation. Upon receipt, we'll test it. If it's defective
and appears unused, we'll ship you a new one right away at no charge.

Missing or Defective Parts After You Begin Assembly: Parts and materials lost or damaged

after construction begins 

are not covered under the terms of this warranty. However, most parts

supplied with VEC kits are relatively inexpensive and Vectronics can replace them for a
reasonable charge. Simply contact the factory with a complete description. We'll process your
order quickly and get you back on track.

Factory Repair After You Begin Assembly:

Kits-in progress and completed kits are

specifically excluded from coverage by the Vectronics warranty.

However, as a

service to customers, technicians are available to evaluate and repair malfunctioning kits for a
minimum service fee of 518.00 (1/2 hour rate) plus 57.00 shipping and handling (prices subject
to change). To qualify for repair service, your kit must be fully completed, unmodified, and the
printed circuit board assembled using rosin-core solder. 1n the event your repair will require
more than an hour to fix (or 536.00, subject to change), our technicians will contact you in
advance by telephone before performing the work. Defective units should be shipped prepaid

Starkville, MS 39759

When shipping, pack your kit well and include the minimum payment plus shipping and
handling charges (525.00 total). No work can be performed without pre-payment. Also, provide
a valid UPS return address and a day time phone number where you may be reached.
