A Message to the Customer

Advantech customer services

Each and every Advantech product is built to the most exacting

specifications to ensure reliable performance in the harsh and

demanding conditions typical of industrial environments. Whether

your new Advantech equipment is destined for the laboratory or the

factory floor, you can be assured that your product will provide the

reliability and ease of operation for which the name Advantech has

come to be known.

Your satisfaction is our primary concern. Here is a guide to

Advantech’s customer services. To ensure you get the full benefit of

our services, please follow the instructions below carefully.

Technical support

We want you to get the maximum performance from your products. So

if you run into technical difficulties, we are here to help. For the most

frequently asked questions, you can easily find answers in your

product documentation. These answers are normally a lot more

detailed than the ones we can give over the phone.

So please consult this manual first. If you still cannot find the answer,

gather all the information or questions that apply to your problem, and

with the product close at hand, call your dealer. Our dealers are well

trained and ready to give you the support you need to get the most

from your Advantech products. In fact, most problems reported are

minor and are able to be easily solved over the phone.

In addition, free technical support is available from Advantech

engineers every business day. We are always ready to give advice on

application requirements or specific information on the

installation and operation of any of our products.

Product warranty

Advantech warrants to you, the original purchaser, that each of its

products will be free from defects in materials and workmanship for

one year from the date of purchase.

This warranty does not apply to any products which have been

repaired or altered by persons other than repair personnel authorized

by Advantech, or which have been subject to misuse, abuse, accident

or improper installation. Advantech assumes no liability under the

terms of this warranty as a consequence of such events.

Because of Advantech’s high quality-control standards and rigorous

testing, most of our customers never need to use our repair service. If

an Advantech product is defective, it will be repaired or replaced at no

charge during the warranty period. For out-of-warranty repairs, you

will be billed according to the cost of replacement materials, service

time and freight. Please consult your dealer for more details.

If you think you have a defective product, follow these steps:

1. Collect all the information about the problem encountered. (For

example, type of PC, CPU speed, Advantech products used, other

hardware and software used, etc.) Note anything abnormal and list

any on-screen messages you get when the problem occurs.

2. Call your dealer and describe the problem. Please have your

manual, product, and any helpful information readily available.

3. If your product is diagnosed as defective, obtain an RMA (return

material authorization) number from your dealer. This allows us to

process your return more quickly.

4. Carefully pack the defective product, a fully-completed Repair and

Replacement Order Card and a photocopy proof of purchase date

(such as your sales receipt) in a shippable container. A product

returned without proof of the purchase date is not eligible for

warranty service.

5. Write the RMA number visibly on the outside of the package and

ship it prepaid to your dealer.

Initial Inspection

Before you begin installing your card, please make sure that the

following materials have been shipped:

• 1 PCA-6275 Dual Pentium®II single board computer

• 2 Pentium II CPUs and 2 cooling fans (optional)

• 1 PCA-6275 user's manual

• 1 bus master & BIOS utility driver

• 2 disks, for OBS Win95 drivers

• 1 FDD cable

• 2 EIDE HDD cables

• 1 printer cable

• 2 temperature sensor cables

• 1 ivory cable for keyboard and mouse

• 1 USBcable

• 1 ATX-to-PS/2 power cable

• 1 dual Pentium II CPU retention module

If any of these items are missing or damaged, contact your

distributor or sales representative immediately.

We have carefully inspected the PCA-6275 mechanically and

electrically before shipment. It should be free of marks and scratches

and in perfect working order upon receipt.

As you unpack the PCA-6275, check it for signs of shipping damage.

(For example, damaged box, scratches, dents, etc.) If it is damaged or

it fails to meet the specifications, notify our service department or your

local sales representative immediately. Also notify the carrier. Retain

the shipping carton and packing material for inspection by the carrier.

After inspection, we will make arrangements to repair or replace the

unit.
