INFORMATION FOR THE USER: 

This device complies with part 15 of FCC rules. Operation is subject to the following two conditions: (1) This device 
may not cause harmful interference, and (2) This device must accept any interference received, including interference 
that may cause undesired operation. 
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 
of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a 
residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed 
and used in accordance with the instructions contained in this manual, may cause harmful interference to radio and

following measures: 

• 

Reorient or relocate the receiving antenna 

• 

Increase the separation between the equipment and the receiver 

• 

Connect the equipment into an outlet on a circuit different from that of the receiver 

• 

Consult the dealer or an experienced audio television technician 

 
NOTE: Connecting this device to peripheral devices that do not comply with CLASS A requirements or using an 
unshielded peripheral data cable could also result in harmful interference to radio or television reception. The user is 
cautioned that any changes or modifications not expressly approved by the party responsible for compliance could 
void the user’s authority to operate this equipment. To ensure that the use of this product does not contribute to 
interference, it is necessary to use shielded I/O cables.
