Displays in the  
startup menu 
The display windows of the startup menu provide information on 
•  The startup procedure (Process) 
•  Instrument model, serial number and version of the CMU base software (Info). 
•  Installed hardware and software options and equipment (Options). Available 
software options are listed with their version numbers. 
•  Progress of the startup procedure (Startup bar graph). 
After terminating the startup procedure, the instrument changes to the last main 
menu or graphical measurement menu of the previous session. 
 
Options 
All the options of the CMU are listed in the section "Installation of Options (Setup – 
Options)" in this chapter. 
 
Further information on the options is to be found in the data sheet. Installation and 
removal of options is described in Chapter 4 of the service manual. 
 
Hotkeys 
During the startup procedure, the hotkeys of the startup menu are available. 
 
 
Default 
 
The Default hotkey activates the default settings of the instrument for all function 
groups and test modes. Alternatively, a reset can be performed any time using the 
RESET key; see section Reset of Instrument Settings (RESET Key) on p. 4.3 ff.  
 
 
Wait 
 
The Wait hotkey prevents the instrument from closing the Startup menu. 
As a result of this, the Wait softkey changes to Cont. with the additional message 
Change to last menu displayed on top. Instead of changing to the last main menu 
or graphical measurement menu of the previous session the measurement can be 
continued by pressing a key (Menu Select, Setup, ...).
