SUNITEC ENTERPRISE CO.,LTD www.sunitec.com Bluetooth USB_Headset Combo(BTH-07C)User Manual About Bluetooth Technology? Bluetooth makes wireless transmission between all mobile and non-mobile facilities possible. This technique utilizes global sound & digital data 2.4G ISM transmission and makes global communication easily. How does Bluetooth COMBO help you? This multi-functional Bluetooth COMBO consists of Headset and Dongle – Class 2. (to be referred as COMBO.) (A) Headset: When it’s under Headset mode, supports all Bluetooth mobile phones and facilities with Bluetooth audio transmission. Powered by a built-in rechargeable battery, it can be either charged via the attached mini AC/DC charger or via the built-in USB connector to the PC USB port. This Bluetooth Unit (a) It wirelessly activates phones located in anywhere within 10 meters(max.) to this unit. (b) Voice Activation: To voice activate phone through microphone of this unit or phone itself, subject to phone built-in with voice activation function. (c) Press to Answer/End: To answer an incoming call or end a conversation without pressing on phones. Simply press the multi-function key on this unit. (d) Volume Adjustment: Simply tune the built-in volume switch to adjust volume. (e) It makes real Hands-Free & safe driving possible. (B) Dongle: When it’s under USB mode, with the attached Windows driver, it support most of the common Bluetooth profiles such as Mobile Phone, Digital Camera, P.D.A., Printer, Mouse, Fax, Bluetooth Serial Port, File Sharing/Transmission, Network Access, Object Push, Dial-up Network, LAN Access,..., etc. It’s the most efficient tool to communicate with the latest Bluetooth-enabled devices. To use, please refer to the attached Window Driver CD. Working Mode: The COMBO is a combination of Headset and Dongle. It’s auto switching in between the two modes by detecting the external connections. It’ll be only switched to USB mode, when it’s connected to the USB port of PC.

Applicant offer a engineering software “BlueSuite” installed on PC to control the EUT. Setting of the software parameters are set as default. Operating frequency are set as testing required. The output power is set as Ext=255, Int=55 (at max. power). Inside the BlueSuite software, there is a BlueTest to control EUT hopping on or off. We select “Txdata1” (which modulated by pseudo-random sequence)and assign the transmit channel(as below). When the EUT is required to transmit in hopping on mode. We select “Txdata2” The lowest operating frequency within Bluetooth specification is 2402Mhz, and highest operating frequency is 2480Mhz. So the frequency above are used as the lowest and highest frequency in the testing, and the middle frequency is set as 2441Mhz. 1.5 Testing Method The testing standard follows CFR 47, Part 15.247 and ANSI C63.4 1992, and measurement method according to Public Notice DA00-705 (March 2000). The Testing procedure is as following: a. The EUT was plug in the USB port of PC and placed on the top of a rotating table 0.8 meters above the ground at a 3m chamber. The table was rotated 360 degrees to determine the position of the highest radiation. b. The EUT was set 3 meters away from the interference-receiving antenna. c. The antenna is a broadband antenna, and its height is varied from one meter to four meters above the ground to determine the maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to heights from 1 meter to 4 meters and the turn table was turned from 0 degrees to 360 degrees to find the maximum reading. e. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode. Report No. : ER/2003/70007 Page : 5 of 46 NOTE: 1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for Peak detection (PK) and Quasi-peak detection (QP) at frequency below 1GHz. 2. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 1 MHz for Peak detection at frequency above 1GHz. 3. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video bandwidth is 300 Hz for Average detection (AV) at frequency above 1GHz. 4. During the Output power testing, the manufacturer attach a test fixture which is a short cable that replace the antenna. So we use conducted method to measure the power. Hence the EIRP is the output power plus the antenna gain in dBi. Due to cable loss, the real value will equal to measured value(show on the instrument) add cable loss.
