Procedure 2. Degaussing (Demagnetizing) the CRT Display
Like most displays, the CRT can be sensitive to large magnetic fields generated from
unshielded motors. In countries using 50 Hz, some 10 Hz jitter may be observed. If this
problem is observed, remove the device causing the magnetic field. Figure 3-2 shows the
motion for degaussing the display.

NOTE In an emergency, you can use a running electric drill or a pencil sharpener
that draws one to two amps through its AC motor winding.
