Specifications: Frequency: 5.8G Channel: 48CH Power: 0/100/200/400/1000mW Voltag: DC7-26V100mw(230mA)/200mw(290mA) Current:400mw(360mA)/1000mw(490mA) Supply Voltag:4V-17 Vclarity: CMOS 700TVL Focal Length: 1.4 mm Antenna: RP-SMA (external thread Inner hole) Volume: 30脳20脳5mm Weight: 36g Guide: 1. LED indication: The red LED indicates the state of working mode or the item when the VTX (flashing 1 time means selecting the channels, flashing 2 times means selecting the bands, flashing 3 times means selecting the power levels). The blue LED indicates the state of Pitmode or the value of item when the VTX( e.g. when selecting the channels, 3 times offlashing means channel 3.When selecting the bands, 3 times of flashing means band C. As for the item of power levels,3 times of flashing means at the power level of 400mW). 2. Working mode indication: -After powering up, the red & blue LEDs will signal the following three items of VTX in turn: chan- nel, band and power level(the flashing times of the red and blue LEDs indicate the item and the value respectively). After that, the LEDs indicate the working modes. -Nomal: The red & blue LED are on. -Pitmode: Use two short press to tum on/off the transmitting(PITMODE ) and then the Red and Green LEDs will be twinkles. When power is st to OFF(PITMODE is effective), you can st bands and channels without interference to others. The AV transmitting distance is only within 1-2 meters when it is in Pitmode. -Press the button twice will toggle the ON/OFF of Pitmode. 3. :Stting -Press and hold the button until the red LED flash 1 time which means the item of channel slecting, then press the button can slect the channels(blue LED flashing times corre- sponds to the channel 1-8). -Press and hold the button again, the red LED will flash 2 times which means the item of band slecting, then press the button can slect the band(blue LED flashing times corre- sponds to the band A-R). -Press and hold the button again, the red LED will flash 3 times which means the item of power level slecting, then press the button can slect the power(blue LED flashing times corresponds to the power level). -Finally, press and hold the button, save and exit the stting of VTX(This step is essntial for stting). -Press the button twice will toggle the ON/OFF of Pitmode. Note: 1.Make sure that there is enough space for airflow when installing the module on the drone. 2.Pleas install the antenna before powering up ,otherwise there is a risk of burningICs. 3.The maximum current of output DC 5V is 500mA. 4. Smartaudio cannot be adjusted at the same time as PWM or keys.The reconstruction of the fligh control will write the default parameter again into the VTX and make the parameters invalid. 5. Please st the parameters in accordance with the local laws and regulations. Package included: 1 x 1W VTX Camera Combo
