Hello Jeff. All commercials radios have locks on them. The lock is so that the radio can be locked into the mounting bracket, #1 so no one steals it, #2 so it does not become a flying projectile if the vehicle is in a crash, and # 3 to keep people from messing with the radios. You would be surprised what people do to radios just to mess with the them, sometimes so they do not have to use them. Some people cut the antennas leads, control cables or power leads. Sometimes they throw the control head out of the vehicle.
You should try to find a set of accessory group for the radio, if you are trying to hook it up, as you probably do not know which wires to connect to. The control head has two power connections, one for the receive side, and one for the transmitter side. If you hook any wire wrong, you might zapp the electronics inside the radio. You will also need to find a key to unlock it as many times the crystals that make the trasnmitter operate have been removed. Hope this helps.

This is the first Mitrek I've had. Thanks for any help. > Jeff KP3FT > > >
