Abstract
A cordless telephone having a handset unit, which is powered by a battery, and a base unit for communicating with a desired party. A telephone conversation with the desired party may be interrupted by activating a hold mode. The hold mode is released by executing predetermined commands, for example, a talk request command. The hold mode is also released after a predetermined period has passed, whereupon the handset unit is placed in a relatively low power standby mode thus reducing the power consumption of the battery of the handset unit.
