Kenwood Protalk XLS 3230B HELP

I bought 4 Kenwood Protalk XLS 3230B radios and I wish to change the frequency settings due to hearing other radio traffic. The manual says to turn the radio off, hold the menu button down while turning on the radio. However when I do this nothing happens and it just turns on! I’ve held it longer and still nothing. Please any input on this would be great. I have romoved the battery cover and it says it’s a 3230B.

As far as I recall that does not change frequency settings on the TK-3230. If you are hearing other traffic on the frequency you are on, you will likely need to program or change QT Tones on the radios. Are you located in the US?
