PURPOSE:To automatically perform the setting of a reception channel by judging whether or not channel setting request data exists in reception data from a transmitter and performing the setting of the reception channel by fixing the reception channel when it exists. CONSTITUTION:When the transmitter is placed near the antenna 1 of a medical monitoring device of automatic reception scan mode and a power source is applied as depressing a call switch, the setting request data is transmitted from the transmitter. In the medical monitoring device, a channel setting signal is inputted from a CPU 10 to a local oscillator, and the reception channel is changed sequentially. When the reception channel is changed only by one channel, the CPU 10 processes by fetching the output of an A/D converter 9, and judges whether or not reception electric field strength is set at a receivable level, and when it is set at the receivable level, the CPU judges whether or not the setting request data exists in the reception data, and when the setting request data is confirmed, the reception channel can be fixed by the command of the CPU 10. |
