Abstract
A method for eliminating the troublesome need to select and erase messages one by one which are stored in a memory of a radio pager. A multi-function switch is provided via which the pager can be switched on and off. A controller of the pager determines if each of messages stored in the memory has been retained in the memory for more than a predetermined period of time. Then, a message is erased in the event that one of: (A) the message has been stored in the memory for more than the predetermined time period and the multi-function switch is operated in a manner which changes the on/off status of the pager; and (B) (i) the message has been stored in the memory for more than the predetermined period of time and the pager is in the power on status, or (ii) the message has been stored in the memory for more than the predetermined period of time when the pager is switched on after being switched off.
