DFBM-NW726-DT0R
-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.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1) this device may not cause interference and
2) this device must accept any interference, including interference that may cause undesired
operation of the device.
RF Radiation Exposure Statement:
ThisTransmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body.
