Garmin GLADIATOR TR-1 - Manual (Page 10)

Heading Command Display
The heading command display will be blank if the
heading command function is unavailable. See
Figure 16. The heading command is available
whenever the autopilot is in heading hold (AUTO)
and the display turn rate command is inactive. It
will display a single horizontal bar until the operator
enters a heading command by turning the command
knob. (See fi gure 12)
The heading command starts at the current heading
and either increments or decrements from there
depending on the direction the knob is turned. The
command is limited to ( + ) or ( - ) 180 degrees from
the current heading. The autopilot will immediately
begin to turn to the new course when the command
is entered.
Turn the dial to the right slowly for one (1) degree
increments. Turn the dial left slowly for one (1)
degree decrements. The increment is rate sensitive.
The faster the knob is rotated the greater the
increments.

There are three annunciator displays indicating the
current autopilot mode; AUTO, STBY, and GPS.
AUTO is displayed if the autopilot is actively
steering the vessel. STBY is displayed if the
autopilot is in standby mode. GPS is displayed
if the autopilot is using the navigation data from
the GPS.

There are a series of bars at the bottom of the display
to indicate the command turn rate or the rudder
position. (It will only show the bars for either mode,
not both at the same time.) See Figure 15.
