What is Bluetooth? By new concept of Multi‐communicator Link, it has been researched since 1994 by Ericsson, Bluetooth SIC (Special Interest Group), which was composed of Ericsson, Nokia, IBM, Toshiba and Intel in Feb. 1998. Currently, it is defined as the global local wireless communication standard. In addition, Bluetooth technology has been established on the industry standard of the local wireless interface for “the innovation of the wireless communication”, and “no wire world”. 2. Introduction of UNB‐2000 UNB‐2000 is wireless headset product to fit on the Bluetooth standard qualification and is able to enjoy wireless high quality stereo digital music with PC, PDA, mobile phone, and PMP, which is supported by the Bluetooth. Moreover it is compatible with Bluetooth USB Dongle and set up the optimum Audio environment in PC. ※ CAUTION THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT. ※ INFROMATION This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures. 3. Product specification ① Play/ Stop ② Previous Music / Next Music ③ Power / Call ④ Vol‐ / Vol+ ⑤ Reset switch ⑥ Recharge cable connection part 4. UNB‐2000 ∙ How to recharge ‐ When charger plug is connected, it is lighting on the red lamp. ‐ When completed charging, the light is off ‐ Average charging time is about 2 hours (When use standard AC adapter) ‐ In charging: Red Lamp on ‐ Complete charging: Red Lamp off Caution – Red lamp may not light off during recharge with USB recharge cable. But, this is not defection. Also, when you use USB recharge cable, recharge hour will be taken more than using AC adapter (About 5 hours). ∙ Turn On‐Off ‐ When push power button for 3 seconds, power is on with “Beep” sound and Red light on. ‐ In operating, blue colored lamp is flickering in each 2 seconds ‐ In operating, push power button for 3 seconds then Red light is off and power is off with “Beep”sound. ※ Caution In your first operation, you need to carry out the course of pairing. Pairing is registration procedure between Headset and Dongle, or Headset and Bluetooth mobile phone or other Bluetooth devices. In addition this enables you to recognise designated Bluetooth devices. Through this registration process, you can enjoy the music or talk. Moreover it removes the line interruption and sets up the security as well. After first pairing, you don’t need to do this again. ※ Usually when it is shipped out, UNB‐2000 is charged only 30%. After purchase, please use it after completely charging up. 5. Pair Bluetooth Headset · Pairing ‐ When pressing power / Call button for 3 second, power lamp is on with “Beep” sound. ‐ Then you must not release the button until the “Blue” lamp is flickering quickly with the beep sound. ‐ This shows that the product is ready to be paired with other devices. ‐ Select “Search the device”or menu of “Inquiry”to the Bluetooth Mobile phone or PC. ‐ Then you will see the word of the search window “UNEEDS UNB‐2000” ‐ Select it then your mobile phone asks PIN number, ‐ Enter the number 0000 and push the“OK”button ‐ Blue lamp of the Headset is begun to flicker out in every 2 seconds and the following message is shown up “to be connected between Headset and PC or Mobile phone”. ‐ It is ready to be used. · Disconnect ‐ Press “Disconnect” to return to stand‐by mode *Pairing with USB Dongle ‐ Insert the USB Dongle in the USB port of your PC. ‐ Press pairing button for 3 seconds ‐ The Blue and Red lamp is flickering quickly. ‐A few seconds later, pairing process will be automatically finished. 6.
