ABSTRACT:
The present invention relates to a cordless telephone unit having a handset and a base unit. The signal strength of a handset which is received by the base unit is examined to determine whether or not the handset is beyond a predetermined range from the base unit. If such determination of out-of-range is made, a warning signal is transmitted from the base unit to the handset and if the handset is not brought within range within a predetermined number of warning signals, a hang up is initiated wherein the handset is placed in an "on" hook condition and the captured telephone line is released.
