Button Controls and LED Indicators Definitions

 

1. Button ⑤ is the channel switch button. Each press of ⑤ will switch to the next frequency point. The corresponding red LED ③ indicator will flash 1, 2, 3, 4, 5, 6, 7, 8 or 9 times. The frequency point selection keys are cyclic.For details, refer to the following table.

Channel	CH1	CH2	CH3	CH4	CH5	CH6	CH7	CH8	CH9
RedLED	Flash Once	Flash Twice	Flash 3 times	Flash 4 times	Flash 5 times	Flash 6 times	Flash 7 times	Flash 8 times	Flash 9 times

 

1. Button ④ is the power on/off control button. When the DC power supply enters the DC jack, the green LED ① is on. Press and hold key ④ for more than 2 seconds, the DC power supply turns off, and all led lights turn off. Press key ④ again for more than 2 seconds, the DC power supply is turned on, and the corresponding channel indicator flashes according to the channel number.
