Danger notices

DANGER
Do not attempt to open the covers of the power supply. Power supplies are not serviceable and
are to be replaced as a unit. ( SPSFD001 )
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. ( SPSFD002 )
DANGER
In the U.S., Canada, and Japan, this product has a 4-wire power cable with a 4-prong plug. Use
this power cable with a correctly grounded power receptacle to prevent possible electric shock.
