4.9 GHz 5.8 GHz Dual Band 2.5W UAV Video Transmitter with 20 km Range

4.9 GHz 5.8 GHz Dual Band 2.5W UAV Video Transmitter with 20 km Range

Description:

Power adjustment:

This video transmitter has 5 power levels: 25/400/800/1500/2500 mW. To adjust the power, press and hold the button for 6 seconds, after which the video transmitter will go into the power adjustment mode. The power is selected in order by pressing the button once. The number of flashes (blinks) of the red indicator R1 will correspond to the selected power: 1 blink - 25 mW, 2 blinks - 400 mW, etc. (pay attention to: “3. Video transmitter power indicator”). To save the selected power, you must wait 5 seconds, after selecting the power - the video transmitter will save the value. (When adjusting the power of the video transmitter - the red power indicator R1 blinks, and the other indicators go out).

Adjusting frequency and channel selection:

Switching frequency group (range grid):To set up the range grid, you need to press the button and hold it for 2 seconds. The video transmitter will go into the range grid setting mode, pressing the button once helps to select the range in order. The number of flashes (blinks) of the blue FR indicator corresponds to the selection of the range grid: 1 blink - range grid A (FR1), 2 blinks - range grid B (FR2), etc. (pay attention to: “4.Frequency table” FR). To save the selected range grid, you need to wait 5 seconds, the range grid will be saved. (When selecting a range grid - the blue FR indicator blinks, and the other indicators go out).

Switching channels:To switch video transmitter channels, you need to press the button once and select the channel you need. Green indicators (LEDs) C1 C2 C3 are responsible for displaying channels. Green LEDs are off – channel 1, the first green LED is on – channel 2, etc. (pay attention to: “4.Frequency table” CH C1/C2/C3). To save the selected channel, you need to wait 5 seconds, the channel will be saved.

Recommendation for choosing frequency range and channel:

To select the frequency 4.9Ghz: you need to transfer the video transmitter to the frequency grid O(FR7) (the blue indicator (LED) should blink 7 times). Then select channel 2 (the first green indicator is on). This frequency range is the most optimal, and corresponds to the frequency: 4921 It is not recommended to use a lower frequency 4884 or the frequency grid R(FR8), since the standard antenna is not designed for this frequency range.
