FCC § 15.21 Information to user Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. FCC §15.105 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 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. RF Exposure Requirements To comply with FCC RF exposure compliance requirements, the device must be installed to provide a separation distance of at least 20 cm from all persons.

WT500 Device User Manual Basic Overview The WT500 is designed to detect the physical presence of water or when ambient temperature meets a user defined threshold. When the WT500 detects water or abnormal temperature under normal operating conditions, the sensor will go into an alarm state. In an alarm state, the device will go into an audible alarm while triggering an alarm to the device group that it is assigned to.

Relevant for this report is the 125 kHz hopping mode which is implemented as FHSS for link setup and as hybrid with only 8 channels during established communication. EUT ports (connected cables during testing): Enclosure Tested datarates Data rate settings LS5 to 12 are supported by the test software, the worst case of the modes was tested for each test case (see test results). Special software used for testing The local TX test modes were set using “LoraNode” software provided by applicant (non-hopping mode tests). Tera Term was used to send commands for hopping mode tests. Tera Term together with Macros and prepared templates in the Option CloudGate LORA gateway, which were provided by the applicant, were used for dwell time tests.
