MESSAGE command.
Simulation Sequences
The user can define up to ten sequences of visibility, status, and
background luminance data.
Each sequence has its own duration. A sequence duration of 0 seconds
switches the sequence off. For a proper operation of Simulation
Sequences, at least one sequence must be enabled by a duration greater
than 0 seconds.
The sequences are defined in the Simulation menu. To enter the
Simulation menu, it is necessary to open the maintenance terminal (see
section Entering and Exiting Command Mode on page 145) and then
enter the menu-driven operation (see section Menu-driven Operation on
page 156).

By default all sequences are disabled (0 s), visibility is set to 5000 m,
status contains of all zeroes and background luminance is set to
20 000 cd/m

. Default settings can be set by (M) RESET SEQUENCES.
Sequences changing is invoked by pressing the appropriate key (A) to
(J). In the
Info Area , the user can accept or modify each set of data. If
the current data is kept, ENTER has to be pressed.
Entering 0 (zero) for a visibility or background luminance value will lead
to an indication of an appropriate value (slashes will be transmitted
instead).
