Safety Information
Safety Information
NOTE: THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS
MANUAL.
1. Save the carton and packing material even if the equipment has arrived in good condition. If you ever need to ship the unit, use only the
original factory packing.
2. Read all documentation before operating your equipment. Retain all documentation for future reference.
3. Follow all instructions printed on unit chassis for proper operation.
4. Do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid.
5. Make sure power outlets conform to the power requirements listed on the back of the unit.
6. Do not use the unit if the electrical power cord is frayed or broken. The power supply cords should be routed so that they are not likely to be
walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs, convenience receptacles, and
the point where they exit.
7. Always operate the unit with the AC ground wire connected to the electrical system ground. Precautions should be taken so that the means
of grounding of a piece of equipment is not defeated.
8. Voltage must be correct and the same as that printed on the rear of the unit. Damage caused by connection to improper AC voltage is not
covered by any warranty.
9. Power down and disconnect the unit from power voltage before making connections.
10. Never hold a power switch in the “ON” position.
11. Do not use the unit near stoves, heat registers, radiators, or other heat-producing devices.
12. Do not block fan intake or exhaust ports. Do not operate equipment on a surface or in an environment which may impede the normal flow
of air around the unit, such as a bed, rug, carpet, or completely enclosed rack. If the unit is used in an extremely dusty or smoky
environment, the unit should be periodically “blown free” of foreign matter.
13. Do not remove the cover. Removing the cover will expose you to potentially dangerous voltages. There are no user-serviceable parts inside.
14. Do not drive the inputs with a signal level greater than that required to drive equipment to full output.
15. Non-use periods. The equipment’s power cord should be unplugged from the outlet when left unused for a long period of time.
16. Service information. Equipment should be serviced by qualified service personnel when:
A. The power supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the equipment.
C. The equipment has been exposed to rain.
D. The equipment does not appear to operate normally, or exhibits a marked change in performance.
E. The equipment has been dropped, or the enclosure damaged.
