General Information 1.1. EUT Description EUT Type ............................. : Bluetooth music streaming receiving device Serial No. .............................. : (n.a, marked #1 by test site) Hardware Version ................. : V1.1 Software Version .................. : Applicant .............................. : Manufacturer ........................ : V1.1 Cobra Electronics Corporation 6500 West Cortland Street, Chicago, IL 60707, USA Universal Microelectronics Co. Ltd. UMEC Shenzhen Company Ltd., Fuyong Town, Baoan, Shenzhen, China Frequency Range .................. : The frequency range used is 2402MHz - 2480MHz (79 channels, at intervals of 1MHz); The frequency block is 2400MHz to 2483.5MHz. Modulation Type .................. : Bluetooth: FHSS (GFSK(1Mbps), ∏/4-DQPSK(EDR 2Mbps), 8-DPSK(EDR 3Mbps)) Antenna Type ........................ : PCB antenna Antenna Gain ........................ : 1.0dBi Note 1: The EUT is a Bluetooth music streaming receiving device, it contains Bluetooth Module operating at 2.4GHz ISM band; the frequencies allocated for the Bluetooth Module is F(MHz)=2402+1*n (0<=n<=78). The lowest, middle, highest channel numbers of the Bluetooth Module used and tested in this report are separately 0 (2402MHz), 39 (2441MHz) and 78 (2480MHz). Note 2: For a more detailed description, please refer to Specification or User’s Manual supplied by the applicant and/or manufacturer. Note 3: a. When power on, the EUT will scan the whole frequency until a Connection command from the other BT devices. b. When receiving the signal from the other BT devices, The EUT transmit aresponse signal. c. The other devices receive the response signal and recognize it, then send a connection command to establish the connection. d. After the connection establish successfully, the data transmission is beginning. At the same time, the both devices will shift frequencies in synchronization per a same pseudo randomly ordered list of hopping frequencies, the hopping rate is1600 times per second. This device conforms to the criteria in FCC Public Notice DA 00-705. e. The bandwidth of the receiver, which is set to a fixed width by the software. Note 4: Bluetooth signal has 9 packages DH1, DH3, DH5, 3DH1, 3DH3, 3DH5, 5DH1, 5DH3, 5DH5, DH5 package is largest, we are testing DH5 in the document. SZ13030017W02 Page 4 of 79 1.2.
