When the signal to receiver is too weak and noise is large, receiver will automatically stop receiving signal according to this setting. When receiver is on and unlocked, push set to adjust. 0 means receiver keep receiving signal at any location and gets maximal distance, 9 means even slight noise will shut off the receiver. Usually 0-1 is a good level. If two transmitters are working on the same channels at same location, this function will automatically 1. DCIN (+5V) 2. OFF/On Switch 3. Lock Button (together with <) 4.

We supply charging station for large amount of device to be charged at the same time. Hints for application: If two groups are located in a very short distance, nearby channels might generate an interference. In this case, in stead of using two close channels, for example, CH1 and CH2, please use channels with more difference, for example, CH1 and CH5, to eliminate the interference between groups. If the receiver volume is over 10, you can hear a slight noise. In this case, please adjust the transmitter volume to maximal level, then you can reduce the receiver volume to avoid the noise.
