Troubleshooting:

1.Adjust volume to the Maximum,and make sure these radios are set to the same frequency and CTCSS.If it is different,it can be set by programming on Chirp and PC.

 

2.Please check if there is a red light when transmitting and a green light when received,

 

3.If the indicator light work well.You can check if they are all on the same frequency and CTCSS by programming.

 

4.Change channel to test if there are the voice prompt?It will help you to check if it is the issue of the microphone;Or you can use the earpiece to test.

 

5.If the communication distance is beyond the RT21 effective range, it will not work,too. So you can move them closer and test if there any voice can be heard.

If the walkie talkies are at the same frequency and CTCSS and within a short distance, it still can’t work, that is the problem of the product itself.you can change it.

 

This is a list of several common for why RT21 can not talk with others, It is not just for RT21 walkie talkie,it also help you check other walkie talkies.

We have older RT21 radios: we purchased two newer RT21 radios, but we cannot get them to communicate with the older radios? We have tried everything in your troubleshooting manual, but they still do not communicate. The two newer radios communicate: is there something else we can try?

We are using 14 of these at at our school. For some reason one of them will not turn on. The base lights up green when the walkie is not on it, however I cannot get a light on when I put a certain walkie on it. The base works for other walkies so I feel safe saying it is not the base. When I put this problem walkie onto a different base I still cannot get it to charge. So I am assuming it is the battery? I cleaned the metal connections for the battery connection and nothing has seemed to help. Any other ideas?

We use the system in our Assisted Living building, sometime the walkie will not change from one channel to another it just stays on that channel

hi, you need to check all your radios with the same settings like frequencies and private calls.
