Accessing Parameter Levels
To help guard against access to advanced programming levels by untrained
personnel, special key combinations must be pressed to gain access.
When power is first applied to the 1391-DES the Basic Display (see
Figure 6.4) will be shown. The Basic Display alternates (every 2 seconds)
between the two displays shown. The alternating display indicates that the
drive is functioning normally. If for some reason the display does not
alternate or is not shown, refer to Chapter 11, Troubleshooting.
