FCC Compliance Statement

NOTE: This equipment has been tested and found to comply with the limits 
for a Class B digital device, pursuant to Part 15 of the FCC rules. These lim-
its are designed to provide reasonable protection against harmful interfer-
ence in residential installations. 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 communica-
tions. However, there is no guarantee that interference will not occur in a 
particular installation.

If this equipment does cause interference to radio or television equipment 
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

Move the equipment away from the receiver

Plug the equipment into an outlet on a circuit different from that to 
which the receiver is powered

If necessary, the user should consult the dealer or an experienced radio/
television technician for additional suggestions

CAUTION: Only equipment certified to comply with Class B (computer 
input/output devices, terminals, printers, etc.) should be attached to this 
equipment, and must have shielded interface cables.

Finally, any change or modifications to the equipment by the user not 
expressly approved by the grantee or manufacturer could void the user's 
authority to operate such equipment.

Each APA-358 is equipped with an FCC compliance label which shows only 
the FCC Identification number. The full text of the associated label follows:

This device complies with part 15 of the 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 inter-
ference received, including interference that may cause undesired
