Electrical Safety
Observe the following safety instructions any time you are connecting or disconnecting
devices attached to the system.
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.
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.
