Abstract: The mobile telephone includes a detector, a timer and an annunciator. The detector transmits a detection signal when the detector detects that the mobile telephone is in a stand-by mode and is located out of a service area. The timer starts measuring a period of time in response to the detection signal. The annunciator makes at least one of sounds and vibration when a period of time measured by the timer reaches a predetermined first period of time.

Abstract: A portable telephone system has a display unit for displaying items of names and telephone numbers retrieved by a retrieval section by using an input character string as a search key from telephone directory information. The display unit displays the items if the number of retrieved items retrieved by using a first input character is lower than or equal to a threshold, and displays only the number of items if the number of retrieved items is larger than the threshold. Desired items are again retrieved by using subsequent input character or characters as a search key. If the number of the thus retrieved items is lower than or equal to the threshold, the extracted items are displayed on the display unit.

Abstract: A radio selective calling receiver includes a message storage section, display section, memory, and automatic display control section. The message storage section stores all, received messages and date/time information of reception of the messages in correspondence with designated selective calling numbers. The display section displays a message stored in the message storage section. The memory stores at least a display start time of a message for each selective calling number. The automatic display control section reads out a latest received message from the message storage section at the display start time stored in the memory in accordance with the date/time information, and outputting the message to the display section.

Abstract: A radio selective call receiver includes a receiving section, a recognizing section, an alarm section and a control section. The receiving section receives a radio signal. The recognizing section detects a message and a selective call number from the received radio signal, and recognizes selectively a reception time of the message as a latest reception time based on a kind of the selective call number. The alarm section generates an alarm in response to an alarm instruction. The control section compares at a comparison timing, a time difference between a current time and the latest reception time and a predetermined time period, and selectively outputs the alarm instruction to the alarm section based on the comparing result.

Abstract: A wireless telephone device comprises: a unit for identifying a telephone number of a received call; a timer for measuring a time period from a time instant of receiving the call; a memory for storing a predetermined message and a predetermined time period both of which correspond to a predetermined telephone number and a display device is provided. The wireless telephone device displays the message on the display device when the wireless telephone device receives a call from the predetermined telephone number and then the call is cut off within the predetermined time period.

Abstract: A selective call radio apparatus includes an operation unit, a display unit, and a message storage unit for storing mail drop messages for respective mail drop selective call numbers. A control unit selects one of the mail drop selective call numbers through an operation of the operation unit, and reads out one of the mail drop messages corresponding to the specified mail drop selective call number from the message storage unit. Also, the control unit controls the display unit to display the read mail drop message based on an elapsed time from reception of the mail drop message.

Abstract: A radio selective calling receiver includes a plurality of notification means, a schedule function section, a storage section, and a timepiece section. Each notification means notifies the reception of a call signal to the receiver. The schedule function section allows to input schedule time zones and icons indicating contents of schedule events in the respective time zones. The storage section stores the schedule time zones and icons, which are input by using the schedule function section, in correspondence with each other. The storage section also stores notification means, of the plurality of notification means, which is selected and set in correspondence with each icon indicating the contents of the schedule.

Abstract: A radio selective calling receiver having means for receiving a message, and displaying the received message on a display section, the receiver comprising storage means 9 in which the maximum number of alphanumeric, katakana or Kanji which can be displayed on one screen of the display section in the double-width size can be stored; determination means 10 for, when a message is received, determining whether or not the number of characters in the received message is larger than the maximum number of characters stored in the storage means which can be displayed on one screen in the double-width size; determination means 11 for determining whether or not the received message contains alphanumeric or katakana characters when the determination means 10 determines that the number of characters in the received message is larger; and control means for converting alphanumeric or katakana characters in the message into the singe-width size when the determination means 11 determines that the received message contains alp

Abstract: A radio pager having an electronic pocketbook function or connectable to such a function and capable of using a schedule function. The pager is capable of storing time zones set by scheduling and alerting means each being allocated to a particular time zone, storing the time of receipt of a paging signal, comparing the time of receipt with the scheduled time zones, and thereby selecting one of the alerting means allocated to the time zone to which the time of receipt belongs. Therefore, only if the user of the pager sets the alerting means in relation to the time zones at the time of inputting a schedule, the alerting means can be automatically and easily controlled in accordance with the schedule information.

Abstract: A radio selective calling receiver which has at least a switch operated by a user to perform operations including resetting of sound generation, ON/OFF of display, time correction, and read access to a stored message and whose switch interrupt processing performed by operating the switch is performed by starting a main clock, includes a radio unit operation determination unit for determining whether a radio unit which demodulates a radio signal received from a base station is performing a reception operation. If the radio unit operation determination unit determines that the radio unit is performing the reception operation, switch interrupt processing is not performed even when the user operates the switch. With this arrangement, an erroneous operation due to harmonic noise generated from the main clock in the reception operation and noise generated from the CPU operated by the main clock during the reception operation of the radio unit can be prevented.
