Information to Users

This equipment has been tested and found to comply with the limits for a Class B digital de-

vices, 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 gener-

ates, uses, and can radiate radio frequency energy and, if not installed and used in accor-

dance with the instruction manual, 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 of 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.

 

WARNING:

 

Changes or modifications not expressly approved by Monnit could void the user’s 

authority to operate the equipment.

RF EXPOSURE WARNING:

 

To satisfy FCC RF exposure requirements for mobile transmitting 

devices, a separation distance of 20 cm or more should be maintained between the antenna 

of this device and persons during device operation. To ensure compliance, operations at 

closer than this distance are not recommended. The antenna used for this transmitter must 
not be co-located in conjunction with any other antenna or transmitter.

The primary function of the Range Extender is to act as a range extender in places 

where wireless sensors are out of range of a KWJ-WSN wireless gateway.
