1 Introduction

The Device Solutions PA0022 SensorII LoRa Board is based on a Semtech SX1276 Low Power Long Range

Multiband RF Transceiver. The PA0022 card has Limited Modular approval under FCC 15C and applicable

Industry Canada RSSs. This document summarizes the requirements for integrating the PA0022 into additional

products.

2 Regulatory Requirements

The Limited Modular FCC and IC approvals for the PA0022 SensorII LoRa Board only authorizes integration into

Device Solutions host products; specifically the Gateway and Sensor products.

To conform to the limited modular approval, the integration must conform to the following:

1. There must be no changes to the antenna system.

2. There must be no changes to the remainder of the module.

3. The product shall be labeled “Contains FCC ID: OXW-PA0022” per FCC requirements.

4. The product shall be labeled “Contains IC ID: 10572A-PA0022” per IC requirements.

5. All integrations must conform to applicable RF exposure limits and associated usage conditions for

installation type (fixed, portable, mobile).

6. The user manual shall include the following text:

This device complies with Part 15 of the FCC Rules. This device complies with Industry Canada’s license-exempt RSSs. Operation of

the device is subject to the following two conditions: (1) The device may not cause harmful interference, and (2) The device must

accept any interference that may cause undesired operation.

This product has been tested and complies with the specifications 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 according to 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 is found 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 or devices

• Connect the equipment to an outlet other than the receiver's

• Consult a dealer or an experienced radio/TV technician for assistance

6. Place the FCC label on the bottom of the enclosure as shown. The top of the label should be pointing in the same direction as the sensor antenna. 7. Apply the label as shown to the enclosure. The top of the label should be pointing in the same direction as the sensor antenna. 5 Example Host Product Installation Instructions 1. Use a Torx T10 driver to remove the screws that hold the top of the Sensor's enclosure to the baseplate. 2. Verify the signal strength at the Sensor.

. Tin the ends of the transducer cable with a soldering iron. 5. Trim the transducer wire such that only 0.25 inches remains uninsulated. 6. Inspect the transducer cable for loose solder and wire strands. Repeat steps 3 through 6 if found. Loose solder or wire strands can cause permanent damage to the Sensor and/or transducer. 7. Remove the battery from the Sensor. Performing the following steps with the battery installed can lead to permanent damage of the device. 11.
