The DBS 824 is designed for use with standard telephone
lines. Direct connection to party lines or coin-operated
phones is prohibited.

Note: When cabling automatic line selection, contact telephone installer or
Panasonic service center. In this case, please inform your telephone company
of the FCC Registration number. The FCC registration number will be found
on your key service unit.
Incidence of Harm to Telephone Line
Should the Terminal Equipment cause harm to the Telephone Network, the
Telephone Company shall, where practical notify the customer that temporary
discontinuance of service may be required. However, where prior notice is
not practical, the Telephone Company may temporarily discontinue service
forthwith, if such action is reasonable in the circumstances. In case of such
unnotified temporary discontinuance of service, the Telephone Company
shall:
e. Promptly notify the customer of such temporary discontinuance of
service.
f. Afford the customer the opportunity to correct the situation which
gave rise to the temporary discontinuance
g. Inform the customer of the right to bring a complaint to the
Commission pursuant to procedures set out in Subpart E of Part 68
of F.C.C Rules and Regulations.

Requirements Model Numbers and FCC Information
Compatibility of the Telephone Network and Terminal Equipment
The Telephone Company sharn make changes in its communication fa&ities,
equipment, operations or procedures, where such action is reasonably
required in the operation of its business and is not inconsistent with the rules
and regulations in F.C.C. Part 68. If such changes can be reasonably expected
to render any customer Terminal Equipment incompatible with Telephone
Company communications Facilities, or other wise materially affect its useor
performance, the customer shall be given adequate notice in writing, to allow
the customer an oppommity to maintain uninterrupted service.
REN Explanation
The REN is useful to determine the quantity of devices your may connect to
your telephone lien and still have all of those device ring when your
telephone number is called. In most, but not all areas, the sum of the REN’s
of all devices connected to one line should not exceed five (5.0). To be certain
of the number of devices that you may connect to our line, as determined by
the REN, you should contact your local telephone company to determine the
maximum REN for your calling area.
Environmental Requirements
Temperature: The environment should be free from excessive temperatures
in order to avoid component damage. Room temperatures should be 32 to
104’ F (0 to 40” C).
Humidity: The environmknt should_be free from excessive humidity, which
may rust metallic parts and degrade performance. Do not install the system
where humidity could condense on its surfaces. Relative humidity ranges
should be between 30 and 90 percent,
Ventilation: Adequate ventilation must be provided to allow upward air
circulation through the cabinet grille.
Gas and airborne particles: To avoid corrosion or oxidation of electrical
contacts, the environment should be free from airborne particles and
corrosive gas.
Eledrical noise: The environment should be free from excessive electrical
noise, which could disturb the operation of digital circuits. The system should
& located at least 10 ft. (3 m) away from welders, dimmers, or other high-
current machines. Phones connected to the system should not be located near
fluorescent lamps, air conditioners, washing machines, TVs, or radios.
Vibration: The environment should be free from excessive vibration, which
could loosen components.
Water Exposure: Because the DBS 824 is an electric device, exposure td
water is dangerous. Do not place anything containing water on the system. Do
Issued 3/l /95 DBS 824-l O-300 1-3

Cleaning Requirements
not install under overhead plumbin g, sprinkler system valves, or in areas that
are susceptible to flooding.
Lighting: Sufficient lighting is required for testing and maintenance.
Lightning Protection/Grounding: The system must be properly grounded to
protect from lightning damage. The following UL conditions must be met to
ensure proper grounding. (For grounding instructions, see page 3-5.)
Cleaning
.
Supplemental and independent equipment grounding conductors are to be
installed between the system and the wiring system ground.
One of the equipment grounding conductors must be a conductor that is as
large or larger than the ungrounded branch-circuit supply conductors. The
equipment grounding conductor is to be installed as part of the circuit that
supplies the system and is to be connected to ground at the service
equipment. Bare, covered, or insulated grounding conductors are
acceptable. Individually covered or insulated grounding conductors should
have a continuous outer finish that is either green or green with one or
more yellow stripes. The equipment grounding conductor should be
connected to ground at the service equipment.
The other equipment grounding conductor shall comply with the general
rules for grounding contained in Article 250 of the National Electric Code,.
NF’PA 70, but its connection to ground shall not depend on the cord and
plug of the system.
The attachment-plug receptacles of the same type as that used by the
systems that are in the vicinity of the DBS 824 are all to be of a grounding
type, and the equipment grounding conductors serving these receptacles
are to be connected to earth ground at the service equipment.
A marking adjacent to the telecommunications jacks must instruct the user
to connect a supplementary equipment grounding conductor before any
telecommunication lines are connected to the product or system.
Use a slightly damp cloth to clean the phones. The phones should never be
cleaned with benzene, paint thinner, or other solvents.
