4. Switch on electrical power to the NCi-4
interface (see “Applying electrical power to
the interface” on page 33).
5. Switch on the air supply to the NC4 system
and set the air pressure (see “Setting the air
pressure” on page 34).
6. Set up and align the NC4 system (see either
“Set-up and alignment – separate system”
on page 40 or “Set-up and alignment – fixed
system” on page 45).
7. Finally, calibrate the system as described in
the publication “
