RF exposure statement 

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment 
should be installed and operated with minimum distance of 20cm between the radiator and your body. This transmitter 

must 

not be co

-

located or operating in conjunction with any other antenna or transmitter.

 

FCC certifications and regulatory information (USA only)

 

FCC PART 15 CLASS B 

These devices comply with part 15 of the FCC rules.   Operation is subject to the following two conditions:

 

(1)

 

These devices may not cause harmful interference, and 

 

(2)

 

These devices must accept any interference received, including interference that may cause harmful operation.

 

RADIO FREQUENCY INTERFERENCE (RFI) (FCC 15.105) 

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 installati

on. 

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 radio/TV techni

cian for help. 

LABELING REQUIREMENTS (FCC 15.19) 

This device complies with Part 15 of 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.

 

If the FCC ID for the module inside this product enclosure is not visible when installed inside another device, then the 
outside of the device into which this product is installed must also display a label referring to the enclosed module FCC ID.

 

Modifications (FCC 15.21)

 

Changes or modifications to this equipment not expressly approved by Synapse Wireless, Inc. may void the user’s authority 
to operate this equipment.
