MAXPRO NVR 5.0 Installation and Configuration Guide 21
14. Damage Requiring Service
Unplug this equipment from the wall outlet and refer servicing to qualified service
personnel under the following conditions:
• When the power-supply cord or the plug has been damaged
• If liquid is spilled or objects have fallen into the equipment
• If the equipment has been exposed to rain or water
• 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.
• If the equipment has been dropped or the cabinet damaged
• 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. Operating Temperature
An operating temperature range is specified so that the customer and installer may
determine a suitable 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
specified operating temperature range.
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.
