NOTE: 

This equipment has been tested and found to 

comply with the limits for a Class H digital device, pur-

suant to part 15 of the FCC Rules. These limits are desi-

gned to provide reasonable protection against harmful 

interference in a residential installation. This equipment 

generates, uses, and can radiate radio frequency ener-

gy and, if not installed and used in accordance with the 

instruction manual, may cause harmful interference to 

radio communications. However, there is no guarantee 

that interference will not occur in a particular installati-

on. If this equipment does cause harmful interference to 

radio or television reception, which can be determined by 

turning the equipment off and on, the user is encouraged 

to try to correct the interference by one or more of the 

following measures:

• 

Reorient or relocate the receiving antenna.

• 

Increase the separation between the equipment and   

 receiver.

• 

Connect the equipment into an outlet on a circuit  

 

  different from that to which the receiver is 

 connected.

• 

Consult the dealer or an experienced radio/TV

  technician for help.

2.3) WEEE Directive

If the time arises to throw away your product, please 

recycle all the components possible.

 

This symbol indicates that when the end-user 

wishes to discard this product, it must be sent 

to separate collection facilities for recovery 

and recycling. By separating this product from 

other household-type waste, the volume of 

waste sent to incinerators or land-fills will be 

reduced and natural resources will thus be 

conserved.

The Waste Electrical and Electronic Equipment Directive 

(WEEE Directive) aims to minimize the impact of electri-

cal and electronic goods on the environment. 4-Acoustic 

comply with the Directive 2002/96/EC and 2003/108/EC 

of the European Parliament on waste electrical finance 

the cost of treatment and recovery of electronic equip-

ment (WEEE) in order to reduce the amount of WEEE that 

is being disposed of in land-fill site. All of our products 

are marked with the WEEE symbol; this indicates that 

this product must NOT be disposed of with other waste. 

Instead it is the user’s responsibility to dispose of their 

waste electrical and electronic equipment by handing it 

over to an approved reprocessor, or by returning it to
