Operation Important Manual： Wireless PTT, headphone and Wireless dongle are matched ready before ex-factory,please follow up the following operation steps: 一、Preparation: When you use the product for the first time, pls use charger to charge for your wireless headset, wireless PTT and wireless dongle over 6 hours.(with charge indicator),to assure it's working in normal and connect wireless donglewith two way radio. 二、Switch on: Press switch on/off button of wirless dongle for 3s until the green indicator flicker qusickly, and it's in standby mode. Then connecting dongle with connect with the two way radio which is power off . Switch on two way radio power, about 5seconds the green indicator for dongle flicker quickly and step connected mode; ( Pls make sure the distance of wireless dongle and wireless headset is within 10m), After seconds, green indicator of both headset and dongle will flicker slowly,which indicates that the connection successfully, and they are in standby mode;(Diagram2) Press for long time till the blue indicator flicker Charge/ low power/ using wireless headphone Dongle Diagram2 三、 Standby Mode: When headset and dongle are in standby mode(i.e approach point 2),power consumpation is quite low. When the other side get call signal input and press PTT, the circuit automatically transfer to work states, the spring process takes about 200ms. When there's no calling within 2mins, the circuit will transfer to standby mode automatically and this will prolong working life time of the battery. 四、 Conversation: Wear wirless headset and wireless PTT, press wireless PTT, green indicator for wireless PTT and wireless dongle bright for long time, it means PTT works normally, at this moment you start calling , pepole on the other side will hear voice. Release PTT,you can hear response from the other side.Press VOC+VOC- button without grade to adjust volume control for long time. 3.PTT: Press PTT: the green indicator will bright for long time when you press PTT,release PTT, the green went out.Charge:When you charge it, the red indicator will turn bright for long time, after charging fully, the red indicator went out.Low power: Green indicator flicker slowly. . 五、 Switch off： 1. Wireless headset: press swith on/off/ button on wireless headset for long time until the green indicator go out and power off. 2. Wireless Dongle: pull out the connector for dongle or switch off two way radio power,Dongle will be automactically power off automatically within 5seconds. 六、Special function and operation： 1. Auotmatic Search mode: After connecting wireless dongle with wireless headset, when wireless headset is far away Dongle, the effective distance is more than 10 metres, wireless dongle will automatically step into searching mode, if the wireless headset back to effective distance 10metres within 5minutes, the wireless dongle will connect to automatically and working normally, if not, wireless dongle and headset will be both power off auto- matically and reduce the consumpation for energy of battery.(Whatever switch off automatically or manual, pls follow to the 2nd approach when you switch on nex time.) 2.Indicator Instruction: 1. Headphone/dongle: Switch on/login:the green indicator flicker quickly Standby: the green indicator flicker tardily Working: the green indicator flicker slowly Lower power:the green indicator strobe tardily. Charge:Red indicator bright for long time, when it's charge fully, the red indicator went out. Receive the singal from PTT: the green indicator will be bright for long time. Charge: Pls charge for headphone, dongle and PTT above 6hours before using the product. They power off automatically when it's in charging.
