Removing Exciter
1. Switch off automatic line fuse 
F2
 (exciter A) or 
F3
 (exciter B).
2. Undo the two captive screws (Torx screwdriver No. 20) from the R&S NetCCU800 and
exciter on the front brackets (next to the handles). 
3. Using the handles, slowly pull out the rackmount from the rack as far as it will go (the
guide rails will engage and lock in place). 
4. Disconnect all cables from the rear panel of the exciter. 
WARNING!
Always make sure that the power supply is disconnected before commencing any service 
work on the transmitter rack. This will prevent injury due to electric shock and avoid dam-
age to the instruments.
