Recommended Hardware design

  1. Hardware
    All unused pins should be left floating; do not ground.
    All GND pins must be well grounded.
    Traces should not be routed underneath the module.
  2. Power Supply
    The transceiver module must be powered from a regulated voltage.
    It is recommended to keep the power supply line for VCC as short and low impedence as possible. Near the power pins it is recommended to insert a ceramic the decoupling capacitor (100nF).
  3. Ground Plane
    It is recommended to have a copper ground plane under the module. The ground plane should be unbroken.
  4. Module Placement (PCB Antenna version)
    The antenna on the PCB has an omnidirectional radiation pattern. To maximize antenna efficiency, an adequate grounding plane must be provided under the module. Instead the areas underneath and surrounding the antenna area must be free of copper.

FCC Statement

This device complies with part 15 of the 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user’ s authority to operate the equipment.
NOTE: 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 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 receivingantenna.
  • Increase the separation between the equipment andreceiver.
  • Connect the equipment into an outlet on a circuit different from that towhich the receiver is connected.
  • Consult the dealer or an experienced radio/TV technician for help important announcement

Important Note:

Radiation 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 20cm between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Country Code selection feature to be disabled for products marketed to the US/Canada. This device is intended only for OEM integrators under the following conditions:

  1. The antenna must be installed such that 20 cm is maintained between the antenna and users,and
  2. The transmitter module may not be co-located with any other transmitter orantenna,
  3. For all products market in US, OEM has to limit the operation channels in CH1 to CH78 for 433M band by supplied firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. (if modular only test Channel1-78)

As long as the three conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.

Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorizationis no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

EndProduct Labeling
The final end product must be labeled in a visible area with the following” Contains FCC ID: 2ANH5-RC-CC1101-434″

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/warning as show in this manual.

Integration instructions for hostproduct manufacturers according to KDB 996369 D03 OEM Manual v01

2.2 List of applicable FCCrules

CFR 47 FCC PART 15 SUBPART C has been investigated. It is applicable to the modular transmitter

2.3 Specific operational useconditions

This module is stand-alonemodular. If the end product will involve the Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system.

2.4 Limited moduleprocedures

This module is Limited modular without shielding, host manufacturer have to consult with module manufacturer for the module limiting conditions when integrate the module in the host. module manufacturer should reviews detailed test data or host designs prior to giving the host manufacturer approval.

2.5 Trace antennadesigns Not applicable
Not applicable

2.6 RF exposureconsiderations
This equipment complies with FCC radiation exposure limits setforth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.

2.7 Antennas
This radio transmitter FCC ID:2ANH5-RC-CC1101-434 has been approved by Federal Communications Commission to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.

2.8 Label and compliance information
The final end product must be labeled in a visible area with the following” Contains FCC ID: 2ANH5-RC-CC1101-434″.

2.9 Information on test modes and additional testing requirements
Host manufacturer which install this modular with limit modular approval should perform the test of radiated emission and spurious emission according to FCC part 15C:15.231 and 15.209&15.207 requirement, only if the test resultcomply with FCC part 15.231 and 15.209&15.207 requirement, then the host can be sold legally.
