Heading Timer
The 'Heading Timer' defines how soon after the last position report the next GPS position transmission triggered
by a heading change will be automatically transmitted. For example, an aircraft that is circling is constantly
changing heading, so the time period between automated GPS transmissions will be determined according to the
'Heading Timer'.
Setting the Heading Timer:
From the 'Tracking Menu', use the arrow keys to navigate to
Heading Timer'.
Press the
ENTER key to select. The 'Heading Timer' screen
displays.
Press the
or
arrow keys to increase the automated
heading variation time interval.
OR
press the
or
arrow keys to decrease the
automated heading variation time interval.
CRITICAL NOTE!
The ‘Heading Timer' must be set to a
lower value than the 'Periodic Timer' to function
successfully. The heading timer will never expire and
trigger a heading change message if periodic messages
are being sent more frequently.
The ‘Heading Timer' may be set between 0 to 60 minutes. The
default is 2 minutes. To disable automatic heading change GPS
transmission, decrease the heading variation time interval to 0.
This will default to 'Disabled'. When disabled, the DZM will not
automatically transmit GPS data on heading change.
Press the
ENTER key to select and save. You are returned
to the 'Tracking Setup' sub-menu.
