<p>The device (1) includes an indicator (29) provided in a monitoring unit (12) to indicate the transmission level and field strength of a high-frequency transmitter provided in a field radiation capsule (8). The field radiation capsule can be set in function position or no-load operation position based on the determined transmission power of the high-frequency transmitter. A switching signal is used for switching the position of the field radiation capsule.</p> |
