<P>PROBLEM TO BE SOLVED: To provide a wireless communication terminal which can notify a user that noncommunicable state will occur even in case of a portable information terminal mounting a stereo speaker, and to provide operation control method and program. <P>SOLUTION: When a transition is made to low voltage operation mode, driving of stereo speakers 8 and 9 is stopped for a driver 21 and a voltage supply control circuit 24 performs selective control of a circuit section being supplied with voltage and a driver. An LED 162 is switched to faint lighting mode and driving of LEDs 161 and 163, a call termination informing LED 10, a sub-display section 5, and the driver 21 is stopped. Since voltage supply to a wireless processing section 12 is stopped, the user cannot communicate with other person but can read/write and display data stored in a storage section 14. <P>COPYRIGHT: (C)2007,JPO&INPIT |
