The ACU-1000’s Automatic Unit ID feature allows customer-specified alphanumeric call signs
to be broadcast at specified times following system transmissions. This allows local officials to
identify which system(s) are currently in operation and can be a valuable aid in finding
duplicate or otherwise inappropriate cross-patches.
The Auto-ID function is triggered when a module’s PTT is applied. This starts a timer that is
user specified to be 5, 10, 15, 30, or 60 minutes. When it is time for the ID to be broadcast, the
module will automatically apply PTT and transmit a voice prompt consisting of the user-
entered alphanumeric call-sign data.
The ACU-1000 system must have a CPM-4 module running version 3.05 (or later) software.
Only DSP-2 or DSP-3 modules can be used with the Auto-ID feature. The DSP modules must
be running version 3.03 (or later) software. The DSP modules must also be in Standard mode
(Hybrid and VoIP Standalone modes do not have this feature).
