• Setting the attenuation to a definite value: see section Setting the Attenuation to a
Definite Value, p. 51
• Adjusting the power level in real-time: see section Performing Real-time Adjustments
to the ATN Attenuation, p. 52

Menu, p. 33 ).
2. Turn the rotary knob to put the cursor before the Set Attenuation menu and press
the knob.
The
Set Attenuation menu appears and displays the current attenuation setting.
The OSICS Mainframe does not support "hot-swap" of modules; for more
