Before installing this equipment, users should make sure that it is permissible to be connected
to the facilities of the local telecommunications company. The equipment must also be installed
using an acceptable method of connection. In some cases, the inside wiring associated with a
single-line individual service may be extended by means of a certified connector assembly. The
customer should be aware that compliance with the above conditions may not prevent
degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility
designated by the supplier. Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request the user
to disconnect the equipment.
Users should make sure, for their own protection, that the electrical ground connections of the
power utility, telephone lines, and internal metallic water pipe system, if present, are connected
together. This precaution may be particularly important in rural areas.
The
Ringer Equivalence Number (REN) assigned to each terminal device provides an
indication of the maximum number of terminals allowed to be connected to a telephone
interface. The termination on an interface may consist of any combination of devices subject
only to the requirement that the sum of the Ringer Equivalence Numbers of all the devices does
not exceed 5.
Laser safety statement
All eMachines y systems equipped with CD and DVD drives comply with the appropriate safety
standards, including IEC 825. The laser devices in these components are classified as “Class 1
Laser Products” under a US Department of Health and Human Services (DHHS) Radiation
Performance Standard. Should the unit ever need servicing, contact an authorized service
location.
Television antenna connectors protection (for
systems fitted with TV/cable TV tuner cards)
External television antenna grounding
If an outside antenna or cable system is to be connected to your eMachines PC, make sure that
the antenna or cable system is electrically grounded to provide some protection against voltage
surges and static charges.
Article 810 of the National Electrical Code, ANSI/NFPSA 70, provides information with regard to
proper grounding of the mast and supporting structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conductors, location of antenna discharge unit,
connection to grounding electrodes, and requirements for the grounding electrode.
Cable distribution system should be grounded (earthed) in accordance with ANSI/NFPA 70, the
National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield
of a Coaxial Cable.
Warning
To avoid electrical shock or equipment malfunction do not attempt to
make electrical ground connections by yourself. Contact the appropriate
inspection authority or an electrician, as appropriate.
Warning
Use of controls or adjustments or performance of procedures other than
those specified in this manual may result in hazardous radiation exposure. To
prevent exposure to laser beams, do not try to open the enclosure of a CD or
DVD drive.
Important
The instructions are for the person who installs cable to the system.
eMachines assumes you are qualified in the servicing of computer equipment
and trained in recognizing hazards in products with electric shock.
