Please carry out the following steps to shift the earhook for wearing it on the other ear. 1. Carefully remove the earhook from the headset 2. Change the direction of the earhook as shown in diagram 2. 3. Carefully replace the earhook on the headset. 4 - Turning the headset ON/OFF - To turn your headset ON: Press and hold the button for 3 seconds, and then the speaker will emit two high tones. When the power is on, the LED in the button starts to flash blue. (Note: The headset will go to pairing mode if you press and hold the button for 5 seconds from OFF status) To turn your headset OFF: Press and hold the button for 3 seconds, and then the speaker will emit two high tones. When the power is off, the LED in the button stops flashing. 5 - Charging the battery - Before using BT400GII you will have to charge the battery for approximate 3 hours to ensure a fully charged battery. 1. Plug the AC power adapter into the DC POWER IN socket situated at the back of the headset. 2. Plug the AC power adapter’s plug into an electrical wall outlet. 3. When charging, the LED in the button is on and re- mains lit until charging is complete. 4. Charge the headset for approximate 3 hours or until the LED in the button extinguishes. 5. Remove the AC adapter from the headset’s AC power jack. DC POWER IN Notice: The headset doesn’t work while it’s charging. 6 - Pairing to a Bluetooth phone - Please follow the instruction below to pair the headset with a Bluetooth cell phone: 1. Ensure the headset is OFF. 2. Press and hold the button for approximately 5 seconds until the headset LED starts to flash with blue and red. 3. Release the button when the LED is flashing, the status indicates that the headset is in pairing mode and waiting to pair with another Bluetooth device. 4. Follow the operating instructions for your Bluetooth phone to start a pairing process. What is Bluetooth pairing? Before using your headset for the first time, you must pair it with a particular Bluetooth cell phone previously. “Pairing” pro- cess creates a unique wireless link between two devices. Once paired, the communication between two devices do not need any authentication or authorization anymore. 7 5. Your phone’s display will indicate that it found one or more Bluetooth devices, the “Bluetake Headset” should be in- cluded in the list, please select it for pairing. 6. The phone’s display then prompt you for a pairing passkey or PIN, please enter four zeros “0000”. 7. When the pairing process is finished successfully, the headset LED will return to normal status of flashing blue only. 8. Your phone’s display may ask you whether you want to change the headset’s name, you can replace the “Bluetake Headset” with any you may prefer. 8 - Answering/Ending a call - Answering a call. After being paired with your cell phone, the headset is now ready to recevie incoming calls without handling the phone. When there’s an incoming call, both the cell phone and the headset will ring simultaneously. Upon hearing the ring tones through the headset’s speaker you can answer the incoming call by pressing button and then speaking normally. Ending a call. You can use either of the ways to end a call: 1. Press the headset’s button to end a call. 2. Press the phone’s keypad to end a call. 9 - Making a call - There are two ways to make calls: 1. Using the phone’s keypad: As general usage, dial the phone number you want to call by pressing the phone’s keypad. You may also hear the dialing tones through the headset. 2. Using the Voice Dialing through the headset: What is voice dialing? Voice dialing is a feature on some Bluetooth phones which al- lows you make calls by saying the name of the person you want to call. The phone compares your voice with your previ- ous recording (called a voice tag). If they match then the phone will automatically dial the corresponding phone number. Not all Bluetooth phones support voice dialing, please refer to your phone’s spec to make sure whether your phone supports this feature. 10 The headset does not have a keyboard so it’s necessary to use voice dialing to make calls. To do this you have to record voice tags for the contacts in your phone address book. If your phone supports voice dialing function, you can use this feature with the headset easily. Note that the voice dial- ing on your phone must be enabled and the voice tags must have been recorded previously. (Please refer to your phone’s instruction on recording and storing voice tags) a. Briefly press the button once. b. After the tone, say the name of the person you want to call. c. The phone number will be dialed automatically by phone after recognizing the correct voice tag. 11 - Appendix I - Button Function buttonTurn ON/OFFPress the button for 3 seconds until the blue LED flashes five times.

The output power and operating frequency are NOT End-user adjustable. Applicant offer a engineering software “BlueTest” install in PC to control the EUT. And the applicant provide an additional UART interface (RS232) to control this Headset. Operating frequency are set as testing required. The output power is set as Ext=255, Int=55. 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. The pseudorandom hopping sequence is produced by the Bluesuite software which is provided by the manufacturer of the chipset. 1.5 Testing Method The testing standard follows CFR 47, Part 15.247 , and measurement method according to Public Notice DA00-705 (March 2000).
