Abstract
A cordless telephone set including a master set and at least one personal set connected to a telephone line via the master set, in which the personal set has a detecting section for detecting whether the personal set is placed in a state wherein a battery within the personal set is charged by a charger, control keys including an outside line key, and a controller for connecting the personal set to the telephone line via the master set when it detects that the personal set is placed in the state not charged based on an output signal from the detecting section. The controller performs a process for connecting the personal set to the telephone line via the master set and a terminating process alternately based on an operation of the outside line key, and invalidating the operation of the outside line key for a predetermined period of time when the personal set is shifted from the state wherein the battery within the personal set is charged by the charger to the state not charged based on the output signal from the detecting section.
