Abstract

Portable electronic device which is sensitive vis-à-vis interferences as a result of the transmit mode of a mobile radio terminal device, particularly a hearing aid, audio device or hand held PC, with a high-frequency interference suppression device (15; 37; 40; 60) which has a high-frequency detector device (45; 65) for detecting a high-frequency transmission signal of a close mobile radio terminal device (17) and a switching element (49) or control element (67) which is connected to the high-frequency detector device at the input side and to a control input or power supply input (9) of the device for at least partially deactivating the device.
