Any device incorporating this module must include an external, visible, permanent marking or label
which states: “Contains FCC ID: H79DFBM-NW726-DT0.”
14. Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user’s manual of the end product which integrates this
module. The end user manual shall include all required regulatory information/warming as shownin
this manual.
15. Federal Communications Commission (FCC)
Statement
15.21
You are cautioned that changes or modifications not expressly approved by the part responsible for
compliance could void the user’s authority to operate the equipment.
15.105(b)
This equipment has been tested and found to comply with the limitsfor a Class B digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmfulinterference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if not installed and
usedin 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 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:
Preliminary Data Sheet Sheet 22 of 23 March 8, 2018
Proprietary Information and Specifications are Subject to Change
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.
