with the power adapter without turning it on. After about 15 minutes, try turning 
on the instrument again.

► 
Make sure that the instrument is turned on.

There might be a problem with the contrast. Make sure you have set the 
contrast properly. See § 8.12: “Changing the Contrast”.

Make sure that the instrument is turned on. 
► 
Make sure that the interface cable is properly connected between the 
instrument and the PC.
