Abstract: A method of operating a cordless telephone system includes the steps of: waiting an incoming call; automatically answering the incoming call and setting the system to a monitoring mode; continuing the monitoring mode as far as it is confirmed that there is a radio connection between a single portable terminal and a main terminal; detecting the termination of communications; and restoring the system to the waiting state in response to the termination of the communications. During a period of monitoring, switching noises are eliminated from monitoring voice because the portable terminals do not transmit data for maintaining the connection to the main terminal in turn.

Abstract: Fish meat as raw material suitable for the manufacture of fish meat powder retaining fresh meat activity is obtained by subjecting low fat fish meat to a bleaching using an aqueous solution of a fatty acid ester of sugar alcohol or sucrose or a mixture thereof in the presence of dissolved calcium or magnesium ions. The pH of the bleaching solution is adjusted to approximately the isoelectric point of the particular fish meat protein being processed.
