your FCC authorization to use this product in the USA. 

3. NOTE: 

This product has been tested and found to comply with the requirements listed 

in FCC Regulations, Part 15 for Class “B” digital devices. Compliance with these 

requirements  provides  a  reasonable  level  of  assurance  that  your  use  of  this 

product in a residential environment will not result in harmful interference with 

other electronic devices. This equipment generates/uses radio frequencies and, 

if  not  installed  and  used  according  to  the  instructions  found  in  the  users 

manual,  may  cause  interference  harmful  to  the  operation  of  other  electronic 

devices. Compliance with FCC regulations does not guarantee that interference 

will  not  occur  in  all  installations.  If  this  product  is  found  to  be  the  source  of 

interference,  which  can  be  determined  by  turning  the  unit  “OFF”  and  “ON”, 

please try to eliminate the problem by using one of the following measures: 

Relocate  either  this  product  or  the  device  that  is  being  affected  by  the 

interference. 

Utilize  power  outlets  that  are  on  different  branch  (circuit  breaker  or  fuse) 

circuits or install AC line filter/s. 

In  the  case  of  radio  or  TV  interference,  relocate/reorient  the  antenna.  If  the 

antenna  lead-in  is  300  ohm  ribbon  lead,  change  the  lead-in  to  co-axial  type 

cable. 

If these corrective measures do not produce satisfactory results, please contact 

the  local  retailer  authorized  to  distribute  this  type  of  product.  If  you  can  not 

locate  the  appropriate  retailer,  please  contact  the  After  Sales  department  of
