Method of and remote control apparatus for remotely controlling a medical appliance

摘要

In a method of remotely controlling a medical appliance frequency signal impulses and group frequency impulses are transmitted alternately from a transmitter to a receiver. In order to improve freedom from interference, the group frequency impulses are amplified in the transmitter and/or receiver by at least 3 dB less than the frequency signal impulses corresponding to command signals. For the same purpose, in a remote control arrangement for performing the method, the amplifier provided in the receiver exhibits at the group frequency a gain factor lower by at least 3 dB than at the frequencies of the frequency signal impulses.
