ABSTRACT:
A system and method that detects an APC control abnormality during transmission power control to prevent circuitry from becoming faulty or damaged and eliminates the need for a pre-shipment process. A cellular phone terminal provides transmission power control. A CPU in the cellular phone terminal generates a predicted transmission power value corresponding to the power value to be transmitted through transmission power control, and compares the predicted transmission power value against a detection output value, which is obtained when a wave detector detects a transmission signal generated from a power amplifier. If the result of comparison indicates that the difference between the predicted transmission power value and detection output value is not smaller than a predetermined value, the CPU halts a signal transmission process.
