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 (see Appendix F, Specifications) 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.
