摘要： In a radio paging receiver which is capable of responding to a message signal specific to the receiver and which comprises a display unit (90) and a message processing section (60) for making the display unit display the message signal, the message processing section monitors the message signal to produce a drive signal after reception of the message signal until the message signal is delivered to the display unit. Responsive to the drive signal, a combination of transistors (3 and 2) keeps power supply of a power source 18 to the message processing section as long as the drive signal is produced. Such power supply is carried out regardless of a state of a power supply switch (20). A decoder (40) makes a speaker (80) generate an alarm in response to the drive signal after the power supply switch is put into an off state. The alarm lasts until the switch is put into an on state. The message processing section may comprise a RAM for storing the message signal as a stored signal and another RAM for storing specific information indicating whether or not the stored signal is delivered to the display unit. Alternatively, such specific information may be stored in a memory included in the decoder.

摘要： In a pager receiver comprising a display circuit and an ROM, a controller produces a test mode signal indicative of a test mode in which either the display circuit or the ROM is tested. Responsive to the test mode signal, the ROM supplies the display circuit with a succession of display signals which are previously stored therein and representative of all alphanumeric symbols displayed by the display circuit, so as to test the display circuit. Alternatively, all of contents stored in the ROM are successively sent from the ROM to the display circuit in response to the test mode signal on testing the ROM, so as to inspect the contents. The test mode signal may be delivered from a transmitting end to the controller in the form of a radio calling signal or given to the controller by manual operation. The test mode signal may specify more than two sorts of tests.

摘要： A paging receiver capable of writing a paging code in an ID ROM according to a received signal. When no data is present in the ID ROM, an ID ROM checking section generates a no-data signal. A mode set code detecting section generates a detection signal when received a predetermined mode set code. A switch is turned on and off by the user of the paging receiver. The receiver allows data to be written to the ID according to a received data on condition that the switch is turned on with the no-data signal and detection signal being generated.

摘要： In a radio display pager, each character of a received multi-character message is checked for error. A first message arrival or a first receive message is stored in a temporary memory and thereafter rewritten into one of main memories when the next message or second message arrival is received. The temporary memory stores the most recent message arrival and the main memories store a plurality of like messages, according to their successive order of earlier arrivals. Each of the messages in both memories contain both error-free and error-containing characters. The characters stored in the temporary memory respectively correspond in position to the characters stored in each of the main memories. A comparison is made between each error-free character in the temporary memory and each of the positionally corresponding error-free characters in one of the main memories in order to detect a match and mismatch. If a mismatch is detected, all characters of each main memory are transferred to an adjacent main memory in order to vacate a storage area. Then, all characters in the temporary memory are transferred to the vacated area for display. If a match is detected, it is counted for all characters of the received message. If the count is smaller than a threshold value, all characters of each main memory are transferred to an adjacent main memory in order to vacate a storage area. All characters in the temporary memory are transferred to that vacated area for display. If the count of the matches is greater than the threshold value, all the error-free characters in the temporary memory are transferred to one of the main memories for display.

摘要翻译： 在无线电显示寻呼机中，检查接收的多字符消息的每个字符的错误。 第一消息到达或第一接收消息被存储在临时存储器中，然后当接收到下一消息或第二消息到达时，将其重写为主存储器之一。 临时存储器存储最近的消息到达，并且主存储器根据其先前到达的连续顺序存储多个相似的消息。 两个内存中的每个消息都包含无错误和含错误的字符。 存储在临时存储器中的字符分别对应于存储在每个主存储器中的字符的位置。 在临时存储器中的每个无错误字符和主存储器之一中的每个位置相应的无错误字符之间进行比较，以便检测匹配和不匹配。 如果检测到不匹配，则每个主存储器的所有字符都被传送到相邻的主存储器以腾出存储区域。 然后，临时存储器中的所有字符都被传送到空闲区域进行显示。 如果检测到匹配，则对所接收消息的所有字符进行计数。 如果计数小于阈值，则每个主存储器的所有字符都被传送到相邻的主存储器以腾出存储区域。 临时存储器中的所有字符都将传输到该空闲区域进行显示。 如果匹配的计数大于阈值，则将临时存储器中的所有无错误字符传送到主存储器之一进行显示。

摘要： A controller stops the power supply to receiver circuits after the end of a call informing operation. The call informing unit can always be made call informing when the own call number is received. The message signal decoding can always be made. A call informing executing unit causes execution of a call informing operation in response to a power supply start instruction when the memory is storing a decoded message signal which has not yet been displayed. The presence of a decoded message signal remaining without being displayed, thus can be informed to the user.

摘要： A battery pack mounting device for portable radio equipment having a built-in antenna. The device determines a position of a battery pack, which powers the equipment, inserted in a battery pack accommodating portion provided in the equipment. Various constants which determine the antenna characteristic of the equipment are controlled on the basis of the determined position of the battery pack, thereby maintaining the optimum antenna characteristic at all times. When the device is applied to a charging unit which charges a rechargeable battery, the opposite electrodes of the battery are electrically correctly connected to a pair of connecting terminals which are provided in the charging unit and connected to opposite poles of a charging circuit as the battery pack is inserted in a battery chamber defined in the charging unit. Even when the battery pack is placed in the battery chamber upside down, the opposite electrodes of the battery are accurately connected to the connecting terminals of the charging unit.

摘要： A selective calling receiver with automatic memory storage and turn-on indication is disclosed. When the receiver is placed in the called state by an incoming signal, audible and/or visual indicator signals actuated by the incoming signal are automatically stopped after a predetermined period of time has elapsed and record of the called state is simultaneously kept in a memory integral to the receiver. Indication of the called state is regenerable at a later time by a switching operation. Indication of the called state is stoppable without recording such indication in memory when a manual reset operation is performed before indication of the called state is automatically stopped.

摘要： A selective calling receiver has a receiver section for receiving and demodulating radio signals. A decoder section, which is connected to the receiver section, operates with first and second levels of power consumption for selectively receiving the demodulated signals and controlling the receiving operation. A voltage converter section is switched off responsive to a signal from the decoder section when the circuit is operational at the first level of power consumption. The voltage converter section is intermittently switched on and off when the circuit is operating, which requires the second level of power consumption. A timer is activating within a predetermined period after the power is switched to the second level.
