Solution

 [mkb-info]Install the bare wire end of each component module in the DAK-2S to the "1" terminal of each C-ML/A master station.[/mkb-info]
[mkb-warning]Answer the call at ONE MASTER only. If the TALK button is pressed at both masters, activating the timing circuit on both, a loud squelch will be heard. Wait 15 seconds until the timing circuit resets before pressing TALK button again.[/mkb-warning]
