Important Safety Instructions

Before using your SDD3, be sure to carefully read the applicable items of these operating instructions and the safety 

suggestions.

 1. 

Read all product instructions.

 2.

  Keep printed instructions, do not throw away.

 3.

  Respect and review all warnings.

 4.

  Follow all instructions.

 5.

  Do not use this unit near water, in unprotected out door areas or in rain or wet conditions.

 

 6.

  Clean only with dry cloth.

 7.

  Do not block any ventilation openings.

 8.

  Install in accordance with KV2 Audio's recommended installation instructions.

 9.

  Do not install near any heat sources such as heat radiators, heat registers, stoves or other apparatus that produce heat.

10.

   Do not defeat the safety purpose of the grounding type plug. A grounding type plug has two blades and a third    

 

  grounding connector. The third connector is provided for your safety. If the provided plug does not fit into your    

 

  outlet, consult an electrician for replacement of the obsolete outlet.

 

11.

  Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles  and the point  

 

  where they exit from the SDD3. The AC mains plug or appliance coupler shall remain readily accessible for operation.

 12.

  Only use accessories specified by KV2 Audio.

 

13.

  The unit is intended for use in a 19" rack. Follow the mounting instructions.

 

14.

  Unplug SDD3 during lightning storms or when unused for long periods of time.

 

15.

  Refer all servicing to qualified service personnel. Servicing is required when the SDD3 has been damaged in any way,  

 

  such as when the power-supply cord or plug has been damaged; liquid has been spilled or objects have fallen into  

 

  the SDD3; rain or moisture has entered the SDD3; the SDD3 has been dropped; or when for undetermined reasons  

 

  the SDD3 does not operate normally.

 16.

  Do not remove top or bottom covers. Removal of the cover will expose hazardous voltages. There are no user    

 

  serviceable parts inside and removable may void the warranty.

 

17.

  An experienced user shall always supervise this professional audio equipment.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER.
NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.

WARNING: 

To prevent fire or electric shock, do not expose this equipment to rain or moisture.
