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 anti-
static 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).
