Abstract:
A method and apparatus are provided by which a radio communication device relays emergency signals across different channels using dual-watch. A dual-watch primary receiver of the radio communication device is allocated to a user selected home channel, while a dual-watch secondary receiver continually scans a pre-stored list of secondary channels for the purpose of detecting a possible emergency signal. The radio communication device upon detecting an emergency signal in either the home channel or any of the scanned secondary channels, relays the emergency signal to all the channels present in the radio communication device's channel list, except for the originating channel.
