Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for two years 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 outof-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, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen 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 merchandise
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.
Declaration of Conformity
CE
This product has passed the CE test for environmental specifications. Test conditions
for passing included the equipment being operated within an industrial enclosure. In

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.
MIO-5250 User Manual

Warning! To avoid damaging the computer, always turn off the power supply
before setting jumpers to clear CMOS. Before turning on the power supply, set the jumper back to 3.0 V Battery On.

3.1 BIOS Setup
AMIBIOS has been integrated into many motherboards for over a decade. With the
AMIBIOS setup program, you can modify BIOS settings and control the various system features. This chapter describes the basic navigation of the MIO-5250 BIOS
setup screens.
Figure 3.1 Setup program initial screen
AMI's BIOS ROM has a built-in Setup program that allows users to modify the basic
system configuration. This information is stored in flash ROM so it retains the Setup
information when the power is turned off.
3.2 Entering Setup
Turn on the computer and then press <F2> or <DEL> to enter the Setup menu.
MIO-5250 User Manual
16
When users first enter the BIOS Setup Utility, users will enter the Main setup screen.
Users can always return to the Main setup screen by selecting the Main tab. There
are two Main Setup options. They are described in this section. The Main BIOS
Setup screen is shown below.

Figure 3.2 Main setup screen
The Main BIOS setup screen has two main frames. The left frame displays all the
options that can be configured. Grayed-out options cannot be configured; options in
blue can. The right frame displays the key legend.
Above the key legend is an area reserved for a text message. When an option is
selected in the left frame, it is highlighted in white. Often a text message will accompany it.
3.3.1 System date / System time
Use this option to change the system time and date. Highlight System Time or System Date using the <Arrow> keys. Enter new values through the keyboard. Press the
<Tab> key or the <Arrow> keys to move between fields. The date must be entered in
MM/DD/YY format. The time must be entered in HH:MM:SS format.

and MIOe module installation.
Quick Installation Guide:
1.
There is a Heatsink / Cooler in the white box inside the package. Carefully
remove the release paper from the thermal pad before installation.
Remove the release paper
2.
3.
There are six screws inside the white box; please install DRAM in the SO-DIMM
socket first, then screw the heatsink as shown below. Four long screws are for
the heatsink; two shorter screws are for the main board.
There are six standoff’s on the MIOe module which can also can be installed
with the screws and copper studs.
