Control Method and LED Indicator

 

1. Button ④ is used to switch band and channel; every time when button ④ is pressed for a short time to switch to the next channel, the red LED ①will flash, 1.2.3.4.5.6.7.8 in turn. The operation can be cyclic; see the following diagram for details!

 

Short press button ④ to switch channel
Red LED	CH1	CH2	CH3	CH4	CH5	CH6	CH7	CH8
	Flash once	Flash twice	Flash for 3 times	Flash for 4 times	Flash for 5 times	Flash for 6 time	Flash for 7 times	Flash for 8 times

 

2. Long press button ④ to switch frequency bands. Long press for 5 seconds and the corresponding blue LED will flash, indicating frequency groups A and B in sequence. This operation can be repeated; see the figure below for details!

3. Button ⑤ is the power adjustment button. Each short press switches the power by one level, cycling between 25mW, 2000mW, and 4000mW. The green LED is the power indicator light, with the following statuses as shown in the figure below: 25mW flashes once, 2000mW flashes twice, and 4000mW flashes three times. Holding the button for 3 seconds enters pit mode, with the green light staying on. See the figure below for details!

Green LED	Pit Mode	25mW	2000mW	4000mW
	Everlasting brightness	Flashes 1 time	Flashes Twice	Flashes 3 times

 

Note

This image transmission device has a temperature protection function. When the temperature of the image transmission device exceeds 100°C, the transmission power of the image transmission device will be reduced by one level. If the temperature remains above 100°C, the transmission power will be reduced by another level until it reaches the lowest power level (25mW). At this point, the temperature of the image transmission device will decrease. When the temperature drops to 95°C, the transmission power will return to the originally set power level
