any idea what error code 5/10 is? looked but could not find anything. thanks

What is the radio model and control head type? Was it originally from a dual drawer VHF/UHF radio system?

The 05 is for the control head on a single radio drawer or for the Systems Interface Unit (SIU) on a dual drawer radio. However, 10 is not a normal error code for a control head problem. Is it possible that you may have a dual radio code plug inside the radio drawer, but a single control head configuration without the SIU?

Translated literally, "05/10" should be control head failure. At least it worked well enough to tell you .
