Dynex DX-BUSB 用户手册

This product is made and tested to meet safety standards of the FCC, requirements and 
compliance with safety performance of the U.S. Department of Health and Human Services, 
and also with FDA Radiation Performance Standards 21 CFR Subchapter J.

This Class B digital apparatus complies with Canadian ICES-003.

This device complies with Part 15 of the FCC Rules. Operation of this product 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 within the limits for a class B 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, may cause harmful interference to radio communications. 
However, there is no guarantee that interference will not occur in a particular installation. 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 technician for help.

To reduce potential radio interference to other users, the antenna type and its gain should be 
so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that 
permitted for successful communication.
