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:
 Correct: start setting up your IBM personal computer.
 Incorrect: change the voltage switch setting.

 Any equipment to which this product will be 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:
 Throw or immerse into water
 Heat to more than 100°C (212°F)
 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.

cuidado:
Ao substituir a bateria, utilize apenas o Número de Peça IBM 36L9077 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:
 Jogue ou coloque na água
 Aqueça a mais de 100°C (212°F)
 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.
