Hereby, [Flysky Technology co., ltd] declares that the Radio Equipment [FS-VK-G4P] is in compliance with RED
2014/53/EU.
The full text of the EU DoC is available at the following internet address: www.flysky-cn.com.
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-located 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.
10.3 Appendix 1 FCC Statement
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.
(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
