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

ore

begin construction.

Return Policy on kits VVhen 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 s

ecified in the

arts 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 $18.00 (1/2

hour rate) plus $7.00 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. In the event your repair will require more than an

hour to fix (or $36.00, subject to change), our technicians will contact you in advance by

telephone before performing the work. Defective units should be shipped prepaid to:

When shipping, pack your kit well and include the minimum payment plus shipping and

handling charges ($25.00 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.
