Yes. There is a main menu accessed from the front panel, but many of the adjustments are in a "service menu" which is not intended to be user-accessible, but the way to access them can sometimes be found online. These radios can also be custom configured by the user using what is called "programming software". Each radio model and variant has it's own programming software. With the software you can set up the channels however you want and do a bunch of other cool stuff. The software is run on a computer and you connect the computer to the radio with the supplied special cable.
WARNING: You can destroy the radio messing with the values in the service menu. If you don't know what you are doing stay away from it! There are people here on this very forum who have "bricked" brand new radios messing in the service menu.
