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.
CAUTION:
This product is equipped with a three-wire power cable and plug for the user's safety.
Use this power cable in conjunction with a properly grounded electrical outlet to
avoid electrical shock.
DANGER
To prevent shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.
