KWS7S3 2.4GHz RF Module User Manual
1. Introduction
KWS7S3 is a 2.4GHz ISM band HDR (high data rate) FH (frequency hopping) transceiver.
It provides three types of digital modulation 16QAM/QPSK/BPSK, and on-air data rate support
12Mbps. The proprietary low MAC feature coupled with high-speed multimedia processor
enables a very high quality wireless multimedia application and a great interference immunity
capability.

2: Putting the module on the carrier board with socket.
4. SPI Digital Interface
All configurations of KWS7S3 are defined by the values of register map.
The register map can be accessed via SPI digital interface coupled with external MCU.
All configuration values need to be properly set into four types of register maps.
The four types of register map are defined as, PMU registers, RF registers, BB registers
and MAC registers. Address setting and data access of PMU registers are defined in
MAC register 0X32H to 0x33H. RF registers are defined in 0X22H to 0X24H, and BB
registers are defined in 0X0EH to 0x10H.

7. IMPORTANT NOTE:
To comply with the FCC RF exposure compliance requirements, the antenna(s) used for
this transmitter must be installed to provide a separation distance of at least 20 cm
from all persons and must not be co-located or operating in conjunction with any other
antenna or transmitter. No change to the antenna or the device is permitted. Any
change to the antenna or the device could result in the device exceeding the RF
exposure requirements and void user’s authority to operate the device.
Notice : The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
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.

To OEM installer:
1. FCC ID label on the final system must be labeled with "Contains FCC ID: TJI-KWS7S3" or
"Contain transmitter module FCC ID: TJI-KWS7S3 ".
2. In the user manual, final system integrator must be ensured that there is no instruction
provided in the user manual to install or remove the transmitter module.
3. Transmitter module must be installed and used in strict accordance with the
manufacturer is instructions as described in the user documentation that comes with the
product. This device complies with the following radio frequency and safety standards.
USA: FCC Part 15C
The user manual of the final host system must contain the following statements:
USA-Federal Communication Commission (FCC)
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 instruction, may cause harmful interference to radio
communication. However, there is no grantee that interference will not occur in a
particular installation. If this equipment dose 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 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 harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
To comply with the FCC RF exposure compliance requirements, the antenna(s) used for
