the Priority 1 channel (see Priority Scan).
Vote scan [requires option KZa0581]
Conventional Channels
Channels in a multicast conventional systems can be added to the scan list and designated as
“voted” channels. When a signal is received on a voted channel the radio checks all voted channels
and selects the channel with the best signal.
If enabled, vote scanning takes place whenever the channel scan switch in on.
NOTE: Channel voting occurs only with Channel Scan and is disabled when Zone Scanning.
Channels programmed as Vote channels are treated as normal scan list channels during Zone Scan
operation.
