RSSI
Function：Check the received signal strength value. Example：RSSI show (two options):

1. RSSI indicates it doesn’t receive any data in the protocol, so it can’t show the received signal strength value.
2. RSSI -52.478 -48.063，-52.478（dBm）Refers to the average value of the signal strength received in the last 20 times or less than 20 times in the protocol (because from power-on to the execution of the RSSI command, no more than 20 data packets are received in the protocol); -48.063 (unit: dBm) refers to the received signal strength of the last intra-protocol packet reception of RSSI command execution.

Main Power Supply

TRM101 can operate with any 3.3V power supply, which comes from data interface connector with good filtered. The power must supply 1A current at least and featured with current-limiting, even if you make radio modem operating on low power mode (0.5W).

IMPORTANT NOTE:
Integration is strictly limited to mobile/fixed categorized end-products where a separation distance of at least
40 cm between the radiating part and any human body can be assured during normal operating conditions. IMPORTANT NOTE:
In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter).then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

The OEM integrator is still responsible for the FCC compliance requirement of the end product, which integrates this module.

LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following “ Contains FCC ID: 2ABNA-
TRM101A” .If the size of the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is required to be available in the users manual: 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 host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
The end user manual shall include all required regulatory information/warning as shown in this manual, include: This product must be installed and operated with a minimum distance of 40 cm between the radiator and user body.

Warnings:
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’ s licence exempt RSS(s).
