But it is not indicated that all the channels to be tested are applicable, but is only the failure for the test operation. Without connecting the antenna, or too closer to the emission source, etc. may lead to the test failure. 3.4.2 RSSI FunctionQuery the received signal strength value. ExampleRSSI 1 RSSI indicate it doesnt receive any data in the protocol, so it cant show the received signal show strength value. 2 RSSI -52.478 -48.063-52.478dBm 5 4Installation of radio Figure 1 shown the installation dimension of data transceiver module, firmly fitted the radio modem onto the mounting surface of user system by holes on radio modem 4 corners Figure 1 Radio Modem installation dimension 5 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 6 Warning This device complies with part 15of the FCC rules. Operation is subject to the condition that this device does not cause harmful interference. 7FCC radiation exposure statement This equipment complies with FCC radiation exposure limits set forth for an controlled environment. This equipment should be installed and operated with minimum distance 60cm between the radiator & your body. Only service personnel have access to the programming capabilities. The end users in all these cases must not be able to program the radios. This Licensed transmitter is approved as a module for installation into the final devices providing this FCC criteria is met:
1. The final device is designed for mobile or fixed operation. 2. The maximum antenna gain to allow compliance with RF exposure requirement that is listed on the Grant of Certification must be followed. 3. If the label of the module is not visible on the final device, the final device should contain the following text:
"Contains FCC ID: 2ABNA-TRM101 6 8Photo 7 Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: 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 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. 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. Conformment la rglementation d'Industrie Canada, le prsent metteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou infrieur) approuv pour l'metteur par Industrie Canada. Dans le but de rduire les risques de brouillage radiolectrique l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonne quivalente (p.i.r.e.) ne dpasse pas l'intensit ncessaire l'tablissement d'une communication satisfaisante. This radio transmitter (identify the device by certification number, or model number if Category II) has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type 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. Le prsent metteur radio (identifier le dispositif par son numro de certification ou son numro de modle s'il fait partie du matriel de catgorie I) a t approuv par Industrie Canada pour fonctionner avec les types d'antenne numrs ci-dessous et ayant un gain admissible maximal et l'impdance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est suprieur au gain maximal indiqu, sont strictement interdits pour l'exploitation de l'metteur
