Channel and Frequency display: Display the current channel and its corresponding frequency (illustrated in Pie 1)
A equates to channel A, and 661 equates to the frequency 661 MHz. Volume display: Only display when you power on (illustrated in Pie 2) Button lock mode display: Assuming lock mode is on, there will be a Lock On on screen while user turns on the receiver.(illustrated in Pie 3) -
Set button
Channel switching: Long press for 2 seconds to do a loop switch in order of A/B/ CID channels. Volume adjustment: Short press set button till the screen appears(illustrated in Pie 2), then short press it again to adjust volume.
It will exit the volume adjustment mode automatically if there is no further operation for 5 seconds, you can also short press power button to exit at once.
Button lock settings: Press and hold the set button and power button together for 3 seconds till the screen (illustrated in Pie 3) appears, then the set button is being locked.

Channel indicator/Battery low voltage indicator and volume adjustment indicator CH A: blue light/ CH B: red light/ CH C: yellow light/ CH D: green light Volume adjustment indicator: The channel indicator acts as a volume indicator during volume adjustment.
When powering on, the channel indicator flashes first, indicating the currently saved volume level, and then lights up continuously. When the battery is low, the corresponding channel indicator flashes at a frequency of 0.5 seconds. -
Set button
A/B/C/D channel switching: Press and hold the set button for 2 seconds to do a loop switch in order of A/B/C/D channels.
Volume adjustment: The current volume level will display when the device is turned on. The number of flashes of the channel indicator when it is turned on corresponds to its volume level (6 levels adjustable).
Each short press of the set button changes the volume level (incremental cycle). The number of flashes of the channel indicator during volume adjustment corresponds to the currently set volume level. -
Charging indicator
The indicator light is always on when the battery is charging, and turns off when the battery is fully charged. -
