A beep will be produced and the green on/off indicator will light up in confirmation.
All the indicators will light up briefly one after the other (as a check), after which the Instructor Unit wil l

will always be unobstructed, and the unobstructed vision indicator (10) will light up in red.

The group indicator (7) indicates which group the Misty Instructor Unit is working with. Student Units set
to a group setting that does not correspond with the setting on a Misty Instructo r Unit will automatically
have unobstructed vision. When the Misty Instructor Unit is switched on, the group last worked with is
automatically chosen as the active group.

Push the “unobstructed vision” switch (11) to return to completely unobstructed vision or to again
limit the vision available.
When the “unobstructed vision” option is switched on, the unobstructed vision indicator (10) lights up.

push the “less vision” switch (13) to decrease the vision available on the Misty Student Units.
The degree of vision can be adjusted in nine steps.
The vision indicators indicate the degree of vision obstruction on the Student Units.
If the indicator lights up on the extreme left, vision is completely obstructed. If it lights up on the extreme
right, vision is completely unobstructed.
Automatically adjusting degree of vision (Automated option)
-
Push the “automated” switch (9) in order to switch the automated vision obstruction option on or
off.
This option controls the degree of vision obstruction fully automatically. The degree of vision is

When the automated option is switched off, the automated indicator (8) is dimmed.
