Modification statement
Worldsensing has not approved any changes or modifications to this device by the user. Any changes or modifications could void the user’s authority to operate the equipment.

Interference statement
This device complies with Part 15 of the FCC Rules and Industry Canada’s licence-exempt RSS standards.
Operation is subject to the following two conditions:

This device may not cause interference, and
This device must accept any interference, including interference that may cause undesired operation of the device.

Wireless notice
This equipment complies with the FCC and ISED radiation exposure limits set forth for an uncontrolled environment. The antenna should be installed and operated with a minimum distance of 20 cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

Permitted antenna
This radio transmitter has been approved by the FCC and ISED to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.

Antenna connection: Through 50-ohms. L connector.

2.4GHz:

Maximum RF Output Power (Conducted/EIRP): FCC13 dBm

Type of antenna
internal = FPC antenna
external = dipole

Antenna gain
internal = 3.9dBi

SubGHz:

Maximum RF Output Power (Conducted/EIRP): F 22 dBm2dBm
Type of antenna
- internal = FPC antenna
- external = dipole
Antenna gain
- internal = -2.9dBi
- external = -0.9dB

Labeling requirements for the host device
The host device shall be properly labelled to identify the modules within the host device. The certification label of the module shall be clearly visible at all times when installed in the host device, otherwise the host device must be labelled to display the FCC ID and IC of the module, preceded by the words “Contains transmitter module”, or the word “Contains”, or similar wording expressing the same meaning.

Contains FCC ID: 2AHN4-WSBRDLR112X

Contains IC: 21260-WSBRDLR112X
Contains FCC ID: 2AHN4-WSBRDLR112X
Contains IC: 21260-WSBRDLR112X

Supported FCC/ISED rules

The WS-BRD-LR112X module has been certified to comply with FCC and ISED rules.
The WS-BRD-LR112X module has been certified to comply with the following FCC rules.
- FCC Part 15.247
- FCC Part 15.209
The WS-BRD-LR112X module has been certified to comply with the following ISED rules.
- RSS-247 Issue 3
- RSS-Gen Issue 5 amendment 2

If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuitry), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

RF exposure considerations

The WS-BRD-LR112X has been tested and certified as a mobile device for use at a minimum distance of 20 cm from the human body with no colocation with other transmitters. If the device is to be used closer than 20cm from the human body and/or with other transmitters simultaneously, the host product manufacturer is required to perform additional evaluation, testing, or testing and Class 2 permissive change. It is required to take responsibility for the module through a change in the

FCC ID (new application). The host product manufacturer must also inform the end user about RF Exposure conditions.
