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 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. 

• Consult your local RadioShack store or 

an experienced radio/TV technician for 
help.

• If you cannot eliminate the interference, 

the FCC requires that you stop using 
your door chime. 

Changes or modifications not expressly 
approved by RadioShack may cause 
interference and void the user’s authority to 
operate the equipment.

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 interference 
received, including interference that may 
cause undesired operation.

The transmitter’s channel setting must be the 
same as the receiver setting. If the door chime 
occasionally sounds without anyone pressing 
BELL, this indicates that the channel settings 
are different. Change the channel settings so 
both the transmitter and the receiver match.
