<p><P>PROBLEM TO BE SOLVED: To provide a remote control transmission apparatus configured to properly discriminate a replacement time of a built-in battery without upsizing a transmitter and reducing the battery lifetime. <P>SOLUTION: The wireless remote control transmission apparatus whose power is supplied by a built-in battery includes: a voltage drop detection means for detecting that the voltage of the battery is less than a prescribed voltage; and a notice means for outputting a notice signal when the detection means detects a voltage drop. Since no excess current is consumed in an ordinary operation, the battery lifetime is extended and a small-sized battery can be used. Further, no complicated display section is required to downsize the transmitter and the manufacture cost can be reduced. <P>COPYRIGHT: (C)2003,JPO</p> |
