Important Safeguards
1. Read Instructions
All the safety and operating instructions should be read before the
appliance is operated.
2. Retain Instructions
The safety and operating instructions should be retained for future
reference.
3. Cleaning
Unplug this equipment from the wall outlet before cleaning it. Do
not use liquid aerosol cleaners. Use a damp soft cloth for cleaning.
4. Attachments
Never add any attachments and/or equipment without the approval
of the manufacturer as such additions may result in the risk of fire,
electric shock or other personal injury.
5. Water and/or Moisture
Do not use this equipment near water or in contact with water.
6. Ventilation
Place this equipment only in an upright position. This equipment
has an open-frame Switching Mode Power Supply (SMPS), which
can cause a fire or electric shock if anything is inserted through the
ventilation holes on the side of the equipment.
7. Placing and 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.
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.
8. 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.
9. Power Cords
Operator or installer must remove power and TNT connections
before handling the equipment.
10. 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.
11. Overloading
Do not overload wall outlets and extension cords as this can result
in the risk of fire or electric shock.
12. 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.
13. Servicing
Do not attempt to service this equipment yourself. Refer all servicing
to qualified service personnel.
14. 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.
15. 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.
16. 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.
17. Field Installation
This installation should be made by a qualified service person and
should conform to all local codes.
18. Correct Batteries
Warning: Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.
19. 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.
20. 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).
21. 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.
22. Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous
condition is not caused by uneven mechanical loading.
23. 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.
24. 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).
