This is one of the more frustrating aspects about these Baofeng models, such as the UV-5R and BF-888S, and one of the reasons we stopped selling them. They are sold like candy on places like Amazon in a way that gives those who are not familiar with radios the misconception that they are just consumer grade, bubble pack walkie talkies that can just be turned to channel 1 out of the box and whatever frequency it is pre-programmed to at the factory can be used by anyone in any manner at all.
This is not how these radios work.
What you have there is a radio that was pre-programmed by Baofeng with a sampling of frequencies. This is a problem for two reasons.
First, depending on the batch and where you purchased them, these channels will be pre-programmed with different frequencies and, sometimes, CTCSS tones or DCS codes.
Second, the frequencies they choose are often not authorized for general consumer or business use, at least not without a license from the FCC. I have seen some of them pre-programmed to frequencies that are not intended for general use by anyone in the US.
The Baofeng UV-5R, BF-888S and others like the ARCShell AR-5 are marketed as general purpose radios, and it causes a lot of problems for those who are not familiar with them. This is one of the primary reasons why the FCC required them to be locked down to the ham bands back in 2017 in order to be sold legally here in the US.
They need to be (re) programmed to the frequencies and service you intend to use it on before use. This means that if they are being used for business operations, they need to be programmed to the specific frequeny(ies) your company is licensed for (assuming your company has a license for them, which technically it should).
If you’re an amateur radio operator (ham), which is really the only service on which some of them are approved for use, they need to be programmed for the frequencies on the ham bands they will be used.
I own a couple of Baofeng radios myself, and I’ve produced a number of articles and videos on them during the past decade, so I am quite familiar with how they work. This is also why I no longer use them. There are much better options available, imho.
If your company is using these and other radios to communicate, someone programmed those radios to do it. If they are talking to each other, but you are unable to fully transmit to them, it is due to either one of the items I stated in my earlier post, or an actual physical hardware defect in the radio, which is not out of the question either, btw.
I don’t know where you purchased it, but I would suggest that if no one in your organization knows how to program it, and you suspect it may be a defective radio, you may want to contact the seller to assist in troubleshooting the issue, if it’s in warranty. The warranty that Baofeng offers is generally worthless, so your only hope there is to ask the seller to cover it. Just try not expect too much from a $29 radio.
You can opt to program the radio yourself. Here is an article and a video on how to do it.
