Do you have a problem between the new version of H777 and the old version of H777?

We have updated walkie talkie H777 frequency, changed the previous frequency of H777 to FRS frequency.

If you had purchased H777 before, current H777 can talk with previous H777 on channel 6 and channel 7. Other channels cannot talk to each other.

If you need them to talk to each other on other channels, you need a programming cable to program them to the same frequency and CTCSS, so that they can work together.

We are sorry to cause your trouble, if you have any problem, please feel free to contact ur support department:
