General Radio Features
Call Alert Page (Conventional and Trunking—
Digital Modes Only)
The Call Alert feature allows a radio to selectively alert another radio,
and to determine whether or not that radio received the alert. A Call
Alert page can be initiated after an unsuccessful Private Conversation
call or as a separate feature.
The O5 Controller Head is capable of responding to a Call Alert
initiated by another radio. It features a unique list of up to 100
preprogrammed ID numbers. A name can be assigned to each ID in
the list for your convenience.
