- RF circuit function:

The major part of this IC is a 902.5-927.5 MHz compliant
transceiver.

- RF signal flow:

The Control signal is encoded into a Data Stream to be the
modulation input for the transceiver.

-Description of Antenna system:

The antenna shall be connected to the RF pin. The RF pin is
matched to 50 Ohm. External antenna was connected by
SMA cable and internal antenna was soldered on board.
the antenna model includes:

1. Monopole antenna soldered on Board.

FCC Part 15

* 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
* You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could
void your 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 oV 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 diVerent from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.

IC Statement

This device complies with Industry Canada licence-exempt RSS standard(s). 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.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2)
l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en
compromettre le fonctionnement.

User Manual

The module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C
"Intentional Radiators" modular approval in accordance with Part 15.212 Modular Transmitter approval. Modular approval
allows the end user to integrate the module into a finished product without obtaining subsequent and separate FCC
approvals for intentional radiation, provided no changes or modifications are made to the module circuitry. Changes or
modifications could void the user's authority to operate the equipment. The end user must comply with all of the
instructions provided by the Grantee, which indicate installation and/or operating conditions necessary for compliance.
The finished product is required to comply with all applicable FCC equipment authorizations regulations, requirements and
equipment functions not associated with the transmitter module portion. For example, compliance must be demonstrated
to regulations for other transmitter components within the host product; to requirements for unintentional radiators (Part
15 Subpart B "Unintentional Radiators"), such as digital devices, computer peripherals, radio receivers, etc.; and to additional
authorization requirements for the nontransmitter functions on the transmitter module (i.e., Verification, or Declaration of
Conformity) (e.g., transmitter modules may also contain digital logic functions) as appropriate.

LABELING AND USER INFORMATION REQUIREMENTS

The RF-434LNA-915 module has been labeled with its own FCC ID number, and if the FCC ID is not visible when the module
is installed inside another device, then the outside of the finished product into which the module is installed must also
display a label referring to the enclosed module. This exterior label can use wording as follows:
Contains Transmitter Module FCC ID: RN489896162JK915 or Contains FCC ID: RN489896162JK915
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

A user's manual for the finished product should include the following statement:

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 oV 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 technician for help.
Additional information on labeling and user information requirements for Part 15 devices can be found in KDB Publication

RF EXPOSURE

All transmitters regulated by FCC must comply with RF exposure requirements. KDB 447498 General RF Exposure Guidance
provides guidance in determining whether proposed or existing transmitting facilities, operations or devices comply with
limits for human exposure to Radio Frequency (RF) fields adopted by the Federal Communications Commission (FCC). From
the FCC Grant: Output power listed is conducted. This grant is valid only when the module is sold to OEM integrators and
must be installed by the OEM or OEM integrators. This transmitter is restricted for use with the specific antenna(s) tested in
this application for Certification and must not be co-located or operating in conjunction with any other antenna or
transmitters within a host device, except in accordance with FCC multi-transmitter product procedures.
Hence the EUT is excluded from SAR evaluation.please also refer to FCC KDB publication 447498 D01 v05:Mobile
Portable RF Exposure.

Module is not approved for use when being powered by AC power lines, either directly or indirectly through another
device.
