1. When the PTT key (launch key) is pressed, the indicator shows red light, which indicates that the radio is in the launch state, at this time, users can speak. When the two users adapt to the same channel { channel 16 }, the other party can receive your speech.

2. When the monitor key is pressed, the indicator shows green light, which indicates that a two way radio is in compulsory receiving state, using this function under the condition that the received signal is very weak. The function is a power hog, so it’s not recommended to use.

3. If only the factory frequency of the same brand and model is no different, users are allowed to call. As for two pieces of two way radios with two different models, as long as the frequency band is same, consumers can change the frequency to achieve call through programmed software.

4. Not each two radio is equipped with channel searching function, generally, there is no mark16 on channel, but with a letter S, that is a function of the channel scan. However, users need to set programming software to use it. Usually, without setting, it is the same as the other channels function, the channel is a temporary fixed frequency.
