User Guide - Precautions
Precautions
General Precautions
Before attempting any modification to, or internal adjustment of the VARIOLITE PC, please read the
following sections carefully. Certain precautions are necessary when handling circuit boards and equipment
containing them. Failure to observe the precautions could result in being unable to operate the equipment,
damage to the product, or in extreme cases, personal injury. It is imperative that precautions are taken at all
stages to avoid electro-static discharges, which will damage boards. Boards fitted with an on-board lithium
battery must be handled carefully to avoid maltreatment of the battery that could create a hazard.
Under no circumstances should the power supply unit be disassembled. Dangerous voltages exist within the
power supply enclosure. Note that the IEC-320 AC supply connector is the AC supply disconnect device.
Mounting
The unit may be specified with a single point fixing suitable for attachment using an M5 to M8 mounting
screw. The fixing plate is attached to the underside of the unit by two M4 x 6mm countersunk screws.
PS/2 Devices
It is important that PS/2 devices (mouse and keyboard) are not connected or disconnected with the unit
powered on. Damage or data corruption may occur if this precaution is not observed.
Electro-Static Discharges
If you are going to open up the unit, it is important to realise that the devices on the cards within this unit
can be damaged by static electricity. Bear in mind that the damage caused by static electricity may vary
from total destruction to partial damage, which may not be immediately obvious. This could have an effect
on the product's reliability and warranty. Before opening the chassis, ensure that you take necessary static
precautions. Ideally you should work at an anti-static bench and wear an approved wrist strap or if that is
not possible, touch a suitable ground to discharge any static build up before touching the electronics. This
should be repeated if the handling continues for any length of time.
If it is necessary to remove a board or electronic assembly, place it into an anti-static bag. This will prevent
any static electricity build up damaging the board. Metallised bags are preferred. Do not use black antistatic bags for any item containing a battery because these tend to be conductive and will discharge the
battery.
On-Board Battery
The processor board is fitted with a Lithium battery. Great care should be taken with this type of battery. If
the battery is mistreated in any way there is a very real possibility of fire, explosion, and personal harm.
Under NO circumstances should it be short-circuited, exposed to temperatures in excess of 100 ºC or burnt,
immersed in water, recharged or disassembled.
Expired batteries remain hazardous and must be disposed of in a safe manner, according to local regulations.
Le panneau de processeur est équipé d’une batterie de lithium. Le grand soin devrait être pris avec ce type
de batterie. Si la batterie est mistreated il y a de dans de toute façon un possibility très vrai du feu,
d’expolosion et de mal personnel. Dans au cunes circonstances il est sous peu circuité, exposé aux
températures au dessus de 100 degrés de centrigrade ou brûlé, immergé dans l’eau, rechargée ou
dissassambled.
Les batteries expirées restent dazaedous et doivent être reejetées d’une façon sûre, selon des règlements
locaux.
BIOS & CMOS Memory
Please be aware that with personal computer products, it is possible to create configurations within the
CMOS memory that make booting impossible. If this should happen, clear the CMOS settings; (see the
description of the Jumper Settings for details).

User Guide - Precautions
Electromagnetic Compatibility
This product meets the requirements of the European EMC Directive (89/336/EEC) and its amending
Directives, and the Low Voltage Directive 73/23/EEC. It is eligible to bear the CE mark. However,
because the unit can be installed in a wide variety of situations, certain conditions have to be applied to
ensure that the compatibility is maintained. Subject to those conditions, it meets the requirements for an
ITE Class A product.
?
The VARIOLITE PC must be supplied with a clean AC supply, and the chassis should be connected
to a sound earth (ground). As a minimum the power cord must be connected to an earthed (grounded)
supply or outlet. Additionally, an earthing stud is provided on the chassis. It is good practice to
connect this independently to a suitable earth in fixed installations.
?
When installing additional items, any recommendations made by the
manufacturer/supplier must be complied with regarding earthing and the installation.
?
The metal back plate of any expansion card must be securely screwed to the chassis of the computer
to ensure good metal-to-metal (i.e. earth) contact.
?
All connector bodies must be securely connected to the enclosure.
?
Most EMC problems are attributable to the external cabling. It is imperative that any external cabling
to the unit is totally screened, and that the screen of the cable connects to the metal end bracket of the
board or the enclosure and hence to earth. It is recommended that round, screened cables with a
braided wire screen be used in preference to those with a foil screen and drain wire. Use metal
connector shells that connect around the full circumference of the cable screen: they are far superior
to those that earth the screen by a simple “pig-tail” connection. This method attempts to extend the
enclosure around the connecting cables, thereby trying to surround the whole of the internal
equipment and external cabling.
?
The keyboard and mouse will play an important part in the compatibility of the processor card since
they are ports into the board. Similarly, they will affect the compatibility of the complete system.
Fully compatible peripherals must be used otherwise the complete system could be degraded. They
may radiate or behave as if keys/buttons are pressed when subject to interference. Under these
circumstances it may be beneficial to add a ferrite clamp on the leads as close as possible to the
connector.
?
USB cables must be high quality screened types suitable for USB 2.0, and peripherals must be
approved to equivalent EMC standards.
?
Where possible ensure that the screens of any external cables are also bonded to a good RF earth at
the remote end of the cable.
component
Failure to observe these recommendations may invalidate the EMC compliance.

Installation - Mounting
INSTALLATION
Mounting
The unit may be mounted in any orientation, but care must be taken to ensure easy access to any removable
media drive (e.g. USB Device). This includes the installation of cables.
It is imperative that the area around the cooling fan inlet and the venting holes are not obscured. Because of
the single cooling fan, a cable passing on top of the fan inlet could present a significant obstruction to the
airflow. Any restriction will lower the maximum ambient temperature at which the unit will operate. Always
use the fixing screws provided. Using longer screws could cause internal damage.
The chassis is fitted with two sets of M4 tapped holes, on the underside of the unit, to facilitate mounting.
There are two near the front edge of the unit (indicated “B” in Fig 1) and two near the rear edge of the unit
(indicated “A” in Fig 1). These may be used to fix the Single Point Mounting bracket. M4 x 6 countersunk
screws are provided with the bracket if you specified the option with your order.

Internal Jumpers
Jumpers
The processor board used in the VARIOLITE PC is largely free of selection jumpers. Most settings are
controlled from the BIOS, and stored in the CMOS memory.
Only two jumpers are significant. One jumper block is used on the board, to clear the CMOS memory. This
would become necessary if the BIOS settings, which are held in the CMOS memory, became corrupted. The
second selects the front side bus (FSB) speed to match the CPU and the memory.
CMOS Clear
To clear the CMOS memory, first switch off the PC power and remove the mains cord, then locate the
3-pin header labelled ‘JP4’ on the processor board between the IDE2 connector and the battery.
Remove the link shorting pins 1 and 2, and place it on pins 2 and 3 for about five seconds. Remove the
link and replace it in its original position. The CMOS has now been cleared and the BIOS will be reset
to the default settings.
Please remember that the board will not function correctly if the CMOS clear link is left in the "Clear"
position.
Having no link fitted is an invalid option.
Set FSB Speed
This will have been set to suit the CPU fitted to the motherboard. If the CPU is changed, check the
position of the jumper on the 3-pin header labelled ‘JP3’. This is located between the CPU and the
edge of the board adjacent to the power supply unit.
Three possible options exist:
For Automatic Selection of the FSB speed, link pins 1 and 2.
For CPUs with 100 (400) MHz FSB, set the jumper to link pins 2 and 3.
For CPUs with 133 (533) MHz FSB do not fit the jumper.
Automatic Selection (link 1-2) is the default option.

Upgrading the System Hardware
UPGRADING THE SYSTEM HARDWARE
Warning
Before attempting any upgrade to the VARIOLITE computer, please read the section "Precautions".
For your personal safety it is important that you ensure that the unit is switched off, and the AC supply is
disconnected. Remember that the unit incorporates an ATX-type of power supply unit. Switching the power off
using the front panel switch does not isolate the AC supply, and under these conditions the +5V DC standby
power is still connected to the motherboard.
For the safety of the equipment, it is important that you observe electrostatic discharge precautions. Do not
remove items from anti-static bags until necessary.
When making any internal changes to the computer, it is imperative that the internal cables follow the original
routes and additional cables are installed as described. Failure to observe this requirement could restrict the
airflow through the unit and cause overheating problems.
Upgrade Options
The user may upgrade the unit by adding more memory to the unit. Upgrading the CPU is possible but requires
disassembly of the unit.
Unauthorised upgrades may invalidate the warranty.
Adding Memory
The VARIOLITE motherboard incorporates two 184-pin DIMM sockets for memory. Each can accommodate a
module of 128, 256, 512MB or 1GB of PC1600 or PC2100 compliant 2.5V DDR SDRAM. This provides for up
to 2GB of system memory. Note that whilst the memory modules need not be the same size, they should be of
the same speed (either PC1600 or PC2100). Generally the memory speed should match the Front Side Bus
speed of the processor. If in doubt, fit PC2100 memory.
Installing additional memory involves removing the top cover, plugging the memory modules into the sockets,
and finally reassembling the unit.
Remove the screws on the top surface of the cover and then lift the cover off.
If changing the memory module, press the two tabs outwards and the module will pop out of the socket.
To add a module, insert the module firmly into the socket until the two tabs lock home

Upgrading the System Hardware
Upgrading the CPU
The CPU fan and heatsink must be removed to gain access to the CPU. This requires the removal of the
HDD/Flash Disk Assembly. There is a specific sequence that must be followed.
Removal Procedure
Switch off the AC supply to the unit. Unplug the AC input connector from the power supply unit.
Remove the top cover.
Remove the hard disk drive assembly.
Disconnect the IDE ribbon cable at the motherboard.
Disconnect the CPU heatsink fan connector from the motherboard.
The heatsink is secured to the chassis through the motherboard by the four outer screws and nylon spacers
at the corners of the heatsink..
Remove the four screws and withdraw the heatsink assembly.
Ease the lever on the CPU socket away from the socket and lift it to release the CPU pins.
Lift the CPU from the socket.
Replacement Procedure
Replacement is essentially the reverse of the removal procedure, with the following notable points.
When fitting the CPU to the socket, care must be taken to align and avoid bending the pins.
Once the CPU is fitted to the socket, the top of the CPU and the heatsink should be wiped clean. Apply a
very thin smear of heatsink compound to the top surface of the CPU and spread it over the whole of the
contact area. It is important that the minimum amount of compound is used, and it is spread as thinly as
possible.
Loosely fit the heatsink assembly to the motherboard. Using the play in the heatsink, slide the heatsink on
the top of the CPU to spread the heatsink as evenly as possible. Then centralising the heatsink, tighten
the fixings. It is important that the screws are tightened progressively and evenly. Do not fully tighten
one screw before moving on to the next: this would prevent the heatsink from lying flat on the CPU. The
heatsink must be in firm contact with the CPU, but not so tight that the motherboard is distorted.
The remainder of the refitting procedure is the reverse of the removal procedure.
Before finally fitting the top cover, apply the AC supply, switch the unit on and confirm that the fan is
rotating correctly.
Switch off and replace the top cover.

Maintenance
MAINTENANCE
The only regular maintenance required is to ensure that the cooling airflow remains unrestricted. To do this, it
may be necessary to clean the inside of the chassis at regular intervals to prevent dust build up inside the unit.
Generally the enclosure design and the wiring layout will ensure that the cooling is stable. However, bear in
mind that any modifications to the installation may cause a restriction of the air vents.
After a period of several years, it may be necessary to replace the battery on the processor board, if it cannot
maintain the CMOS memory whilst the AC power is disconnected.
Replacing the Processor Battery
The processor board includes a small 3V-lithium battery (type CR-2032) to retain the BIOS settings in the
CMOS memory when the unit is powered down. Before attempting to replace the battery, please read the
precautions detailed in the introductory section. Remember that even discharged batteries can present a real
personnel hazard if mistreated.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to the manufacturer's instruction.
ATTENTION
Il y a danger d'explosion s'il y a remplacement incorrect de la batterie.
Remplacer uniquement avec une batterie du même type ou d'un type
recommandé par le constructeur.
Mettre au rébut les batteries usagées conformément aus instructions du
fabricant.
The battery is located on the motherboard adjacent to the AGP (brown) socket, underneath the hard disk
drive mounting plate.
Remove the hard drive assembly as indicated in the section on Upgrading the CPU:
The battery is mounted vertically in the holder held in place by the clip in the top.
Do NOT under any circumstances try to remove the battery with metallic tools (pliers, tweezers etc.).
They will short out the battery with possible disastrous results.
To remove the battery, push the top of the retaining clip away from the AGP connector to force it away from
the battery, then lift the battery clear of the holder.
Replace the battery by one of the same type, ensuring that it is fitted with the positive terminal facing the
CPU, and that the clip is fully engaged. When the battery has been replaced, the BIOS settings will revert to
their default settings. Reset them as necessary to suit your application.
Fuses
There are no user-serviceable or replaceable fuses within the unit.
