ADVANTECH aims to meet the customer’s expectations for post-sales service and
support; therefore, in addition to offering 2 years global warranty for ADVANTECH’s
standard products, a global extended warranty service is also provided for customers
upon request. ADVANTECH customers are entitled to complete and prompt repair
service beyond the standard 2 years of warranty.
Standard products manufactured by ADVANTECH are covered by a 2 year global
warranty from the date of shipment. Products covered by extended warranty and
cross-region repair services against defects in design, materials, and workmanship,
are also covered from the date of shipment. All key parts assembled into ADVAN-
TECH system products such as LCD, touchscreen, power supply, and peripherals,
etc., will be also covered by the standard 2 year warranty.
Repairs under Warranty
It is possible to obtain a replacement (Cross-Shipment) during the first 30 days of
purchase (45 days for Channel Partners), if the products were purchased directly
from ADVANTECH and the product is DOA (Dead-on-Arrival).
DOA Cross-Shipment excludes any customized and/or build-to-order products. The
Cross-Shipment agreement signed by customers is required for initiating/releasing
cross shipment with ADVANTECH confirmation and verification. The only conditions
for Cross-Shipment are: a) the return must not be damaged, altered or marked, b) all
parts and accessories must be included as originally shipped; and c) proof of pur-
chase must be included. Any returns that do not meet mentioned requirements
above, or any wrong user settings/configurations will be denied, or subject to addi-
tional handling/service charges as determined by the ADVANTECH Repair Service
Department.
For those products which are not DOA, the return fee to an authorized ADVANTECH
repair facility will be at the customers’ expense. The shipping fee for reconstructive
products from ADVANTECH back to customers’ sites will be at ADVANTECH’s
expense.
Exclusions from Warranty

The product has been found to be defective after expiry of the warranty period.
Warranty has been voided by removal or alteration of product or part identifica-
tion labels.
The product has been misused, abused, or subjected to unauthorized disas-
sembly/modification; placed in an unsuitable physical or operating environment;
improperly maintained by the customer; or failure caused which ADVANTECH is
not responsible whether by accident or other cause. Such conditions will be

2.1.3 Jumper Description
Cards can be configured by setting jumpers. A jumper is a metal bridge used to close
an electric circuit. It consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To close a jumper, you
connect the pins with the clip. To open a jumper, you remove the clip. Sometimes a
jumper will have three pins, labeled 1, 2 and 3. In this case you would connect either
pins 1 and 2, or 2 and 3.
The jumper settings are schematically depicted in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes.
Setting Function
1-2 +5 V
2-3 +3.3 V
Warning! To avoid damaging the computer, always turn off the power supply
before setting jumpers. Clear CMOS. Before turning on the power sup-
ply, set the jumper back to 3.0 V Battery On.

2.2.2.5 IDE, CDROM Hard Drive Connector (CN8)
The board provides 1 IDE channel with which you can attach up to two Enhanced
Integrated Device Electronics hard disk drives or CDROM to the board.s internal con-
troller. Its IDE controller uses a PCI interface.
This advanced IDE controller supports faster data transfer, PIO mode 4, Multi-word
DMA mode 2 and an UltraDMA-33 interface.
Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. This package includes one 44-
PIN IDE cable that can connect to 1.8" and 2.5" drives.
1. Connect one end of the cable to Hard Drive connector. Make sure that the red
(or blue) wire corresponds to pin 1 on the connector, which is labeled on the
board (on the right side).
2. Plug the other end of the cable into the Enhanced IDE hard drive, with pin 1 on
the cable corresponding to pin 1 on the hard drive.
(See your hard drive’s documentation for the location of the connector).
If desired, connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of the cable. If you
install two drives, you will need to set one as the master and one as the slave by
using jumpers on the drives. If you install only one drive, set it as the master.
2.2.2.6 Solid State Disk
The board provides a CompactFlash. card type I socket.
CompactFlash (CN9)
The CompactFlash card shares a Primary IDE channel which can be enabled/dis-
abled via the BIOS settings.
