FS-MG4

Digital Proportional Radio Control System

12

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 televison 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.

To assure continued compliance, any changes or modifications not expressly approved by the party responsible for 
compliance could void the user's authority to operate this equipment. 

This equipment 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.

Caution!
The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this 
equipment. Such modifications could void the user authority to operate the equipment.
1.  The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm 

from all persons and must not be co-lacated or operating in conjunction with any other transmitter.End-users 

and installers must be provided with antenna installation instructions and transmitter operating conditions for 

satisfying RF exposure compliance.

2.  Move all your channels to the desired position.
3.  Select [All channels] and then [Yes] in the confirmation box. 

8. Certification
