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 operations. Note: This product 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 product 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 product 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 receiving antenna. Connect the equipment into an outlet on a circuit different from that to which the receiver is Increase the separation between the equipment and receiver. connected. Consult the dealer or an experienced radio/TV technician for help. Please take attention that changes or modification not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. This equipment should be installed and operated with a minimum distance 20cm between the radiator and your body. When the FCC ID is not visible when the module is installed inside a device, then the outside of this device will display a label referring to the enclosed module. 11.2 IC Statements This device complies with Industry Canada licence-exempt RSS standard(s). 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. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. ISED RF exposure statement:
This equipment complies with ISED radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator&
your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Document: LoRMur User Manual Date : February 19, 2020 Page 12/13 LoRMur User Manual When the ISED certification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed will also display a label referring to the enclosed module. 11.3 General Statements The module is limited to Oceasoft installation only, Oceasoft is responsible for ensuring that the end-
user has no manual instruction to remove, or install module Therefore, the final host product must be submitted to [SyChip] for confirmation that the installation for the module into the host is in compliance with regulations of FCC and IC Canada. Specially, if an antenna other than the model documented in the Filing is used, a Class 2 Permissive Change must be filed with the FCC. Changes or modifications not expressly approved by the manufacturer could void the users authority to operate the equipment. The LoRa module is for use with external antenna ONLY, with a gain < 2.0dBi. This module has been approved by FCC to operate with the antenna provided. 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.
