Group settings
The MISTY system works with six different groups, making it possible to carry out training exercises in
the same space with several MISTY units at the same time.
A MISTY Student Unit will respond to a MISTY Instructor Unit only if both units are set to the same
group. Each Misty Student Unit must also be identified as unit A or unit B. Always make sure that one
Misty Student Unit is set as unit A and the other as unit B.
You can change the settings of the Student Unit via a set of micro switches in the battery compartment.
Switch off the unit using the switch on the top, and then open the
battery compartment on the back of the unit. The micro switches
are located to the left of the battery (see figure 3.2). The easiest
way to set the switches is by using a ballpoint pen or a similar
pointed object.
Important! The
Misty Student Unit must be SWITCHED OFF
when adjusting group settings!
Figure 3.2: micro switches
Using switches 1, 2 and 3, you can set the unit to the correct
group (1 through 6). Using switch 4, you can identify the Misty
Student Unit as unit A or B (switch to the right selects for unit A;
switch to the left selects for unit B).
Figure 3.3 displays all the possible combinations for selecting the
different groups. The squares marked with an x indicate the
position of the micro switches.
