OT-020C User's Guide 1. Introduction 1.1 Bluetooth technology Bluetooth is a standard of wireless communication. Bluetooth technology is a kind of short distance wireless communication technology and an open global criterion. The Bluetooth products work on universal industry, science, medical (ISM) frequency. In order to avoid interference, adopt jumping frequency technique, divide 2.4GHz ~ 2.48GHz into 79 channels, transmit data at 1600 time/sec. The transmission distance is about 10m (Class II). ISM frequency of 2.4GHz is free open frequency, no need to apply for license. 2. Operation instructions: Introduction 2.1 OT-020C Bluetooth headset key-press’s image and key-press function explanation A. MFB key-press: realize power on, power off, receiving, voice dialing, hang-up, pairing etc. B. Volume +: realize increasing volume, mute, rejecting incoming call, redialing etc C. Volume -: realize decreasing volume etc. 2.2 Power on In the state of power off, long press MFB, speaker will make a short BEEP sound. Blue light flashes. Then OT-020C will power on. 2.3 Power off In the standby state, long press MFB, speaker will make a long BEEP sound. Blue light closes. Then OT-020C will power off. 2.4 Pairing Firstly, confirm OT-020C Bluetooth headset is in the state of power off and is in the effective distance with other Bluetooth devices. a.

Short press MFB. b. Then blue indicator changes from slow flash to quick flash. c. If OT-020C Bluetooth headset is power off, please make it power on firstly. After re-link mobile phone automatically (press one time to connect with mobile phone), press MFB again, then you can receive the incoming call. 2.7 Voice dialing When OT-020C Bluetooth headset is power on and connects with mobile phone, you are going to dial by voice. a. Short press MFB, you can hear short BEEP sound, then enter voice dialing. b. Speak the people’ name saved in telephone book of mobile phone, such as David. c. Mobile phone will dial according to the number in telephone book of mobile phone. The function demands Bluetooth mobile phone have voice recognition function. 2.8 Rejecting an incoming call When OT-020C Bluetooth headset is power on and connects with mobile phone, telephone in but don’t want to receive, long press VOL+, then the incoming call is rejected. Last number redialing: In the standby state, long press volume +. 2.9 Volume adjustment In the state of standby, speaking and calling waiting, short pressing volume + or volume -, you can adjust volume. Short pressing volume +, the volume adds one step; Short press volume -, the volume decreases one step. When volume is adjusted to maximum or minimum, it will sound a warning by “Du Du”. 2.10 Switch between headset and mobile phone With the successful connection between the phone and headset when speaking is made, by long pressing the volume button, the BEEP sound can be heard, the voice will be transferred to the phone from the headset, by long pressing the volume again, the BEEP sound can be heard ,then the voice will be transferred to the headset from the phone.(these functions are different according to the different operations of the phone .please see the instructions of the mobile phone for details about the concrete ways of switching. 2.11 Low battery warning When the battery of OT-020C Bluetooth headset is not enough, blue light closes, red light flashes, and speaker make short BEEP sound. Then you should charge OT-020C Bluetooth headset. 2.12 Redial automatically When OT-020C Bluetooth headset is power on but disconnects with devices, also in effective distance with mobile phone, if mobile phone had connected and paired with OT-020C, it will rebuild connection with mobile phone automatically. 2.13 Charging Plug DC jack of power adapter into charging interface of charging socket, then place OT-020C Bluetooth headset into charging box, close the upper cover of charging box, then plug in power supply of power adapter, if red light flashes, then charging begin; after red light goes out, then charging end. 2.14 End speaking In the process of speaking, short press MFB, it can end speaking. 3 Performance parameter Item Parameter Standard Bluetooth V2.0+EDR Effective range 10m without obstacle Audio frequency 15bits S/N 70db Frequency 2.4GHZ-2.48GHZ ISM Band Connection Point-to-Point Speaking time 4-5hrs Standby time after pairing About 70hrs Standby time while power on and non-pairing Close automatically after 10 minutes RF Power 0dBm (class II) Power consumption of power supply 18~25mA when speaking Battery capacity Rechargeable Lithium Polymer Battery 70mAh Charging 5V DC, AC adapter input/100-240V Charging time 2~3hrs Using temperature 0 °C to +60°C Storage temperature -20°C to +85°C Pairing code 0000 Pairing One-to-one, allow many primary device but need to connect by turns Operation voltage 3.0~4.2V Receivin…
