Responding to a Scan
During scanning, your radio stops on any channel / group where
matching activity is detected. After the transmission is over the radio
remains on the active channel for a programmed time known as "Hang
Time" (the Hand Time is adjustable and must be programmed by your
RCA Communications Systems dealer).
1. Press the [PTT] button during "Hang Time" to respond to the call.
The LED lights up red.
2. Release [PTT] button to listen.
Note: If you do not respond within the "Hang Time" period, the radio
will resume scanning.
Scan Lists
Scan lists are created and assigned to individual channels/groups. The
radio scans for activity by cycling through the channel/group specified
in the scan list for the current channel/group. The RDR4220 radio has
32 scan lists with up to 32 members each and the RDR4250/4280
has 250 scan lists with 32 members each. Each scan list supports a
mixture of both analog and digital channels. You can add, delete, or
prioritize channels by editing the scan lists.
