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:
① When the power-supply cord or the plug has been damaged.
② If liquid is spilled or objects have fallen into the equipment.
③ If the equipment has been exposed to rain or water.
④ 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.
⑤ If the equipment has been dropped or damaged the cabinet.
⑥ When the equipment exhibits a distinct change in performance—this indicates a need for service.
14. Replacement Parts
 When replacement parts are required, ensure the service technician uses 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.

18. Operating Temperature
 An operating temperature range is specified so that the customer and installer may determine a suitable 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 specified operating temperature range.
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. Grounding (Earthing)
 Connection of ground wire is highly recommended to protect the DVR from external electric shock, such as lightening,
electrical surge.
