Do not use this equipment near water or in contact with water.
6. Accessories
Do not place this equipment on an unstable cart, stand or table.
The equipment may fall, causing serious injury to a child or
adult, and serious damage to the equipment. Wall or shelf
mounting should follow the manufacturer's instructions, and
should use a mounting kit approved by the manufacturer.
This equipment and cart combination should be moved with
care. Quick stops, excessive force, and uneven surfaces may
cause the equipment and cart combination to overturn.
7. Power Sources
This equipment should be operated only from the type of power
source indicated on the marking label. If you are not sure of
the type of power, please consult your equipment dealer or
local power company.
8. Power Cords
Operator or installer must remove power and TNT connections
before handling the equipment.
9. Lightning
For added protection for this equipment during a lightning
storm, or when it is left unattended and unused for long periods
of time, unplug it from the wall outlet and disconnect the
antenna or cable system. This will prevent damage to the
equipment due to lightning and power-line surges.
10. Overloading
Do not overload wall outlets and extension cords as this can
result in the risk of fire or electric shock.
1. Objects and Liquids
Never push objects of any kind through openings of this
equipment as they may touch dangerous voltage points or
short out parts that could result in a fire or electric shock.
Never spill liquid of any kind on the equipment.
12. Servicing
Do not attempt to service this equipment yourself. Refer all
servicing to qualified service personnel.
13. Damage requiring Service
Unplug this equipment from the wall outlet and refer servicing
to qualified service personnel under the following conditions:
A. When the power-supply cord or the plug has been damaged.
B. If liquid is spilled, or objects have fallen into the equipment.
C. If the equipment has been exposed to rain or water.
D. If the equipment does not operate normally by following the
operating instructions, adjust only those controls that are
covered by the operating instructions as an improper
adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the equipment to its normal operation.
E. If the equipment has been dropped, or the cabinet damaged.
F. When the equipment exhibits a distinct change in
performance — this indicates a need for service.
14. Replacement Parts
When replacement parts are required, be sure the service
technician has used replacement parts specified by the
manufacturer or that have the same characteristics as the
original part. Unauthorized substitutions may result in fire,
electric shock or other hazards.
15. Safety Check
Upon completion of any service or repairs to this equipment,
ask the service technician to perform safety checks to
determine that the equipment is in proper operating condition.
16. Field Installation
This installation should be made by a qualified service person
and should conform to all local codes.
17. Correct Batteries
Warning: Risk of explosion if battery is replaced by an incorrect
type. Dispose of used batteries according to the instructions.
18. Tmra
A manufacturer’s maximum recommended ambient
temperature (Tmra) for the equipment must be specified so that
the customer and installer may determine a suitable maximum
operating environment for the equipment.
19. Elevated Operating Ambient Temperature
If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater
than room ambient. Therefore, consideration should be given
to installing the equipment in an environment compatible with
the manufacturer’s maximum rated ambient temperature
(Tmra).
20. Reduced Air Flow
Installation of the equipment in the rack should be such that the
amount of airflow required for safe operation of the equipment
is not compromised.
21. Mechanical Loading
Mounting of the equipment in the rack should be such that a
hazardous condition is not caused by uneven mechanical
loading.
22. Circuit Overloading
Consideration should be given to connection of the equipment
to supply circuit and the effect that overloading of circuits might
have on over current protection and supply wiring.
Appropriate consideration of equipment nameplate ratings
should be used when addressing this concern.
23. Reliable Earthing (Grounding)
Reliable grounding of rack mounted equipment should be
maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit
(e.g., use of power strips).
