iv Installation and Using Guide

Safety Information
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage
on metal parts of the system or the devices that attach to the system. It is the
responsibility of the customer to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock.
Before installing or removing signal cables, ensure that the power cables for
the system unit and all attached devices are unplugged.
When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from the
existing system before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to
prevent a possible shock from touching two surfaces with different electrical
potentials.
During an electrical storm, do not connect cables for display stations, printers,
telephones, or station protectors for communications lines.

vi Installation and Using Guide

Handling Static-Sensitive Devices
Attention: Static electricity can damage this device and your system unit. To avoid
damage, keep this device in its antistatic protective bag until you are ready to install it.
To reduce the possibility of electrostatic discharge, follow the precautions listed below:
vLimit your movement. Movement can cause static electricity to build up around you.
vHandle the device carefully, holding it by its edges or its frame.
vDo not touch solder joints, pins, or other printed circuitry.
vDo not leave the device where others can handle and possibly damage the device.
vWhile the device is still in its antistatic package, touch it to an unpainted metal part of
the system unit for at least two seconds. (This drains static electricity from the
package and from your body).
vRemove the device from its package and install it directly into your system unit
without setting it down. If it is necessary to set the device down, place it on its
static-protective package. (If your device is an adapter, place it component-side up).
Do not place the device on your system unit cover or on a metal table.
vTake additional care when handling devices during cold weather, as heating reduces
indoor humidity and increases static electricity.
