TT2BHF200WIRELESS HANDSFREE CARKIT

1. Before using your Hands-Free BHF-200 Status Indicators 1) Power LED – Power on mode 2) LED 1 -> Connecting Status Stand by Mode : two times blinking every two second Pairing Mode : blinking continuously. Active Mode : Power on continuously 3) LED 2 -> Call Activity Status Sending and Receiving Phone Call : Blinking shortly Using Hands Free : Power on continuously 4) LED 3 -> ( Low battery Status ) : LED blinking continuously 2. Charging Your Hands-Free Use the vehicle power charger provided. BHF-200 uses a rechargeable battery that must be fully charged before you use it For the first time. Connect the supplied vehicle power charger to power socket and then to your Hands-Free. The status of indicator on Vehicle charger will be illuminated red while charging and change to Green when the Hands-Free is fully charged. It takes approximately 2 hours to fully charge the Hands-free NOTICE: If battery is Low, Blue light of the LED 3 will blink in every second. 3. BLUETOOTH PAIRING Before using your hands-free for the first time with a mobile phone or another Bluetooth device, you must first pair it with the device. Follow the steps below for most devices. You can also refer your phone user guide. 1) Turn on both devices. For Hands-free, press the multifunction button for two seconds. 2) Place the Hands-free in pairing mode by pressing and holding the volume down Button for six seconds. Release the button when the status indicator begin to flash with beep sound. NOTICE: If the pairing is not success for two minutes, the Hands –free becomes to stands-by mode. 3) Use your phone’s menu to search for Bluetooth audio devices and select “BHF-200” 4) When the phone display asks for a pass key, enter “0000”. The Bluetooth icon appears on the display, once the hands-free successfully paired. If the Hands-free stops responding to button presses, you must reset the Hands-free. 4. USING YOUR HANDS-FREE 1) Power On / Off Press the multifunction buttons for two seconds in order to turn of the device. Press the multifunction buttons for five seconds in order to turn off the device. 2) Connect the Hands-free to the phone When disconnected, the Hands-free can be re-connected to the phone by simply short pressing the multifunction button. 3) Disconnect the Hands-free from the phone Press the volume up /down button simultaneously 4) Answer / End / Place a call To answer a call, short press the multifunction button. To end a call, long press the multifunction button for two seconds. To place a call using voice dialing, short press the multifunction button. If you are on a calling using your phone handset, you can transfer the call to your Hands-free by two times press of the multifunction button. 5) Call transfer back to phone To transfer a call from your Hands-free back to your phone, two times press of the Multifunction button. 6) Call reject To reject a call without answering when the Hands-free is ringing, long press the volume up and multifunction buttons simultaneously. 7) Last number redial To redial the last number, two times press the multifunction button. 8) Volume Up / Down Press the volume up / down button to adjust the volume Additional page Regulatory Information FCC compliance Information This device complies with part 15 of FCC Rules.

ATTACHMENT FCC ID: TT2BHF200 The peak radiated output power (ERP) is calculated as follows: EIRP = P + G + 2.15Where, EIRP = 3.22 dBm + (-1.0) dBi + P = Power input to the antenna (mW) EIRP = 4.37 dBmG = Power gain of the antenna (dBi) Power density at the specific separation: S = PG/(4R 2 π) Where, S = (2.1 * 0.79) / (4 * 20 2 * π)S = Maximum power density (mW/cm 2 ) S = 0.0003 mW/cm 2 P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the (20cm = limit for MPE) The Maximum permissible exposure (MPE) for the general population is 1 mW/cm2 . Estimated safe separation: R = √(PG / 4π)Where, R = √(2.1 * 0.79 / 4π)P = Power input to the antenna (mW) R = 0.36 cmG = Numeric power gain of the antenna R = Distance to the center of the radiation of the (20cm = limit for MPE) The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log -1 (-1.0 / 10) G = 0.79 ** MPE Calculations ** The EUT will only be used with a separation of 20 centimeters or greater between the antenna and the body of the user. The MPE calculation for this exposure is shown below. The power density at 20cm does not exceed the 1 mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules.

RE : RF exposure information FCC ID : TT2BHF200 Model Name: BHF200 Wireless Handsfree Carkit To whom it may concern: This device is categorically excluded from routine environmental because it operate at very low power level. The equipment is deemed to comply with the SAR or MPE limits without testing due to this very low power level (EIRP < 3 mW) Sincerely, __________________________ Taek-Soo Kim A.

After the trace being stable, the reading value between the peaks of the adjacent channels using the marker-delta function was recorded as the measurement results. The spectrum analyzer is set to: Span = 3 MHz (wide enough to capture the peaks of two adjacent channels) RBW = 30 kHz (1% of the span or more) Sweep = auto VBW = 30 kHz Dete…
