ABSTRACT:
In a radio communication apparatus having an individual call number for use in receiving a call signal and a message signal representing a message and following the call signal, the apparatus being capable of operating in one of a standby mode wherein the apparatus is waiting to receive a call signal that is coincident with the individual call number and a message received mode wherein the apparatus has received a call signal that is coincident with the individual call number, a push button switch (11 or 12) is provided for setting an operation mode of a display unit (24), and a control unit (32) is provided to control the display unit to make the display unit carry out a display operation of the received message. A slide switch (31) is provided to set an inhibition mode of operation, in which the slide switch is positioned at a predetermined position (P3), whereby operation of the push button switch is inhibited from controlling the display unit to carry out a display operation when the apparatus is in the standby mode of operation, and therefore prevent unintentional operation of the display unit caused by undesired activation of the push button switch and consequently conserve battery power. Further, the control unit cancels the inhibition operation mode in response to receiving a call signal having said individual call number, whereby standby operation mode is necessarily changed to the message received.
