Voltage Supply Switch Settings
Your IBM Personal Computer
might have voltage switches,
which must be set correctly for your voltage supply. If your
monitor or system unit has a voltage switch, complete these
steps to make sure each switch is set correctly:
1. Determine the correct voltage switch setting for your area:
Voltage Supply Range Voltage Switch
Setting
100-127 V 110 V
200-240 V 220 V
2. Locate the voltage switch on the back of your monitor or
system unit. If the setting shown on the switch is:
q
Correct: start setting up your IBM personal computer.
q
Incorrect: change the voltage switch setting.

attached must also be connected to properly wired
receptacles.
When possible, use one hand to connect or disconnect
signal cables to prevent a possible shock from touching
two surfaces with different electrical potentials.
Electrical current from power, telephone, and
communications cables is hazardous. To avoid shock
hazard, connect and disconnect cables as described
following when installing, moving, or opening covers of
this product or attached devices.
To Connect
1. Turn Everything OFF.
2. First, attach all cables to
devices.
3. Attach signal cables to
receptacles.
4. Attach power cord(s) to
outlet.
5. Turn device ON
To Disconnect
1. Turn Everything OFF.
2. First, remove power
cord(s) from outlet
3. Remove signal cables
from receptacles.
4. Remove all cables from
devices.

Caution:
When replacing the battery, use only IBM Part Number
36L9077 or an equivalent type battery recommended by
the manufacturer. If your system has a module
containing a lithium battery, replace it only with the same
module type made by the same manufacturer. The
battery contains lithium and can explode if not properly
used, handled, or disposed of.
Do not:
q
Throw or immerse into water
q
Heat to more than 100°C (212°F)
q
Repair or disassemble
Dispose of the battery as required by local ordinances or
regulations.
Caution:
When a CD-ROM drive is installed, note the following.
Use of controls or adjustments or performance of
procedures other than those specified herein might result
in hazardous radiation exposure.
Removing the covers of the CD-ROM drive could result in
exposure to hazardous laser radiation. There are no
serviceable parts inside the CD-ROM drive. Do not
remove the CD-ROM drive covers.

4
DANGER
Some CD-ROM drives contain an embedded Class 3A or
Class 3B laser diode. Note the following.
Laser radiation when open. Do not stare into the beam,
do not view directly with optical instruments, and avoid
direct exposure to the beam.
≥32 Kg ≥55 Kg
(70.5 lbs) (121.2 lbs)
Caution:
Use safe lifting practices when lifting your machine.
Caution:
Electrical current from power, telephone, and
communication cables can be hazardous. To avoid
personal injury or equipment damage, disconnect the
attached power cords, telecommunications systems,
networks, and modems before you open the covers,
unless instructed otherwise in the installation and
configuration procedures.

PERIGO
Para evitar choques elétricos, não conecte ou
desconecte nenhum cabo, nem efetue instalação,
manutenção ou reconfiguração deste produto durante
uma tempestade com raios.
Para evitar choques elétricos:
q
O cabo de alimentação deve ser conectado a um
receptáculo corretamente instalado e aterrado.
q
Todos os equipamentos aos quais este produto será
conectado devem também ser conectados a
receptáculos corretamente instalados.
Quando possível, utilize uma das mãos para conectar ou
desconectar cabos de sinal, para evitar um possível
choque ao tocar duas superfícies com potenciais
elétricos diferentes.
A corrente elétrica proveniente de cabos de alimentação,
de telefone e de comunicação é perigosa. Para evitar
choques elétricos, conecte e desconecte os cabos
conforme descrito a seguir, ao instalar, movimentar ou
abrir tampas deste produto ou de dispositivos
conectados.
Para Conectar
1. DESLIGUE tudo.
2. Conecte primeiro todos os
cabos nos dispositivos.
3. Conecte os cabos de sinal
nos receptáculos.
4. Conecte o(s) cabo(s) de
alimentação nas tomadas.
5. LIGUE o dispositivo.
Para Desconectar
1. DESLIGUE tudo.
2. Remova primeiro o(s)
cabo(s) de alimentação das
tomadas.
3. Remova os cabos de sinal
dos receptáculos.
4. Remova todos os cabos
dos dispositivos.

cuidado:
Ao substituir a bateria, utilize apenas o Número de Peça
IBM 33F8354 ou um tipo de bateria equivalente
recomendado pelo fabricante. Se seu sistema possuir um
módulo com uma bateria de lítio, substitua-o apenas pelo
mesmo tipo de módulo, produzido pelo mesmo
fabricante. A bateria contém lítio e pode explodir se não
for utilizada, manuseada e descartada de forma
adequada.
Não:
q
Jogue ou coloque na água

Aqueça a mais de 100°C (212°F)
q
Conserte nem desmonte.
Descarte a bateria conforme requerido pelas disposições
e regulamentações locais.
cuidado:
Quando uma unidade de CD-ROM estiver instalada,
observe o seguinte.
A utilização de controles ou ajustes ou a execução de
procedimentos diferentes daqueles especificados nesta
publicação pode resultar em exposição perigosa à
radiação.
A remoção das tampas da unidade de CD-ROM pode
resultar em exposição a radiação perigosa de laser. Não
existem peças que possam ser consertadas no interior
da unidade de CD-ROM. Não remova as tampas da
unidade de CD-ROM.

7
PERIGO
Algumas unidades de CD-ROM contém um diodo de
laser da Classe 3A ou da Classe 3B. Observe o
seguinte.
Radiação de laser quando aberto. Não olhe diretamente
para o feixe de laser, não olhe diretamente com
instrumentos óticos, e evite exposição direta ao raio.
≥32 Kg ≥55 Kg
(70,5 lbs) (121,2 lbs)
cuidado:
Utilize práticas seguras para levantamento de peso ao
levantar sua máquina.
cuidado:
A corrente elétrica proveniente de cabos de alimentação,
de telefone e de comunicação é perigosa. Para evitar
ferimentos pessoais ou danos aos equipamentos,
