Bluetooth (BT) Connection 1. Select the “BT” wireless connectivity by the slider switch. 2. Power on the unit by pressing the Power On button. 3. White LED will light up, which indicates the BT is ready 4. Search and pairing the BT with your computer. • Startup manual, select “Control Panel”. • “Control Panel”, select “Devices and Printers” • “Devices and Printers”, press the button “add a device”, then select MTRAY-F1 BT address to pair. In general, the MTRAY-F1 BT name is called “F1_XXXXXXXXXXXX”. And it has also printed on the product label at the bottom side, indicated by “BM”. 5. When the BT is connected, White LED will be off while Blue LED will be on. 6. Set the corresponding “COM” port number in the application program which is generated after paired. The “COM” number can be found in the “Device Manager”.。 5 WiFi Connection 1. Select the “WiFi” wireless connectivity by the slider switch. 2. Power on the unit by pressing the Power On button. 3. White LED will light up, after 20 seconds, Yellow LED will be blinking while White LED is off indicates that WiFi is ready. 4. Identify the IP address with the camped router admin page. The unit has its WiFi address also printed on the product label at the bottom side, indicated by “WM”. 5. When the WiFi is connected, blinking Yellow LED will be stayed on. 6. Set the IP address in the application program then connected with the notebook/computer. 6 Regulatory Information Federal Communications Commission (FCC) Compliance 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 when the equipment is operated in a commercial environment. 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 • Consult the dealer or a qualified radio/TV technician for assistance FCC NOTICE: To comply with FCC part 15 rules in the United States, the system must be professionally installed to ensure compliance with the Part 15 certification. It is the responsibility of the operator and professional installer to ensure that only certified systems are deployed in the United States. The use of the system in any other combination (such as co-located antennas transmitting the same information) is expressly forbidden. RF Exposure Information and Statement： The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device has also been tested against this SAR limit. This device was tested for typical body-worn operations with the back of the handset kept 10mm from the body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain a 10mm separation distance between the user's body and the back o…
