2.5.6 [RF ON / OFF]-Key
The RF output signal is switched on and off again using the [RF ON / OFF] key. This does not influence
the current menu. When the output signal is switched off, the message "RF OFF" is displayed in the
LEVEL indication of the header field. If RF OFF is displayed, the 50-Ω source resistance is maintained.

2.5.7 Reset Overload Protection
The SMIQ is protected against overload by an external signal which is fed into the RF output. If an
external signal is too high, the overload protection responds. This state is indicated by means of the
message "RF OFF" in the LEVEL indication in the header field and the message "OVERLOAD" in the
status line.
Ø Reset the overload protection by pressing the [RF ON / OFF] key.
